E5–2070 Filed 4–29–05; 8:45 am] BILLING CODE 7590–01–P Nuclear Power Plants During this period, no events occurred at U.S. nuclear power plants that were significant enough to be reported as AOs. NUCLEAR REGULATORY COMMISSION Report to Congress on Abnormal Occurrences Fiscal Year 2004 Dissemination of Information Section 208 of the Energy Reorganization Act of 1974 (Pub. L. 93– 438) defines an abnormal occurrence (AO) as an unscheduled incident or event which the U.S. Nuclear Regulatory Commission (NRC) determines to be significant from the standpoint of public health or safety. The Federal Reports Elimination and Sunset Act of 1995 (Pub. L. 104–66) requires that AOs be reported to Congress annually. During fiscal year 2004, 17 events that occurred at facilities licensed or otherwise regulated by the NRC and/or Agreements States were determined to be AOs. The report describes four events at facilities licensed by the NRC. One event involved a uranium hexafluoride release VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 at a fuel cycle facility. Another event, also at a fuel cycle facility, revealed excessive uranium concentrations found in ash deposits in various locations in an incinerator. A third event involved a patient undergoing therapeutic brachytherapy treatment. The fourth event involved an unintentional excessive dose of sodium iodide (I–131) administered to a patient. The report also addresses 13 AOs at facilities licensed by Agreement States. [Agreement States are those States that have entered into formal agreements with the NRC pursuant to Section 274 of the Atomic Energy Act (AEA) to regulate certain quantities of AEA licensed material at facilities located within their borders.] Currently, there are 33 Agreement States. During FY 2004, the NRC received notification of 13 events that occurred at Agreement State-licensed facilities, including 8 therapeutic medical events, 3 diagnostic medical events, 1 event involving an unintentional dose of I–131 to an embryo/fetus, and 1 event involving an extremity overexposure to a radiopharmacy trainee. As required by Section 208, the discussion for each event includes the date and place, the nature and probable consequences, the cause or causes, and the action taken to prevent recurrence. Each event is also being described in NUREG–0090, Vol. 27, ‘‘Report to Congress on Abnormal Occurrences, Fiscal Year 2004.’’ This report will be available electronically at the NRC Web site https://www.nrc.gov/ reading-rm/doc-collections/nuregs/ staff/. Fuel Cycle Facilities (Other Than Nuclear Power Plants) During this period, two events occurred at U.S. fuel cycle facilities that were significant enough to be reported as AOs. 04–01 Uranium Hexafluoride Release at Honeywell Speciality Chemicals, Inc. in Metropolis, Illinois Date and Place—December 22, 2003; Honeywell International, Inc., Honeywell Specialty Chemicals, Metropolis, Illinois. Nature and Probable Consequences— On December 22, 2003, a uranium hexafluoride (UF6) release occurred from one of the plant’s chemical process lines. The release occurred due to improper valve alignment which caused inadvertent pressurization of the PO 00000 Frm 00096 Fmt 4703 Sfmt 4703 system. The licensee did not have a written procedure for a process that was performed infrequently and relied on the operator’s memory to perform the required actions. The release lasted approximately 40 minutes. The licensee observed a visible cloud crossing the site boundary and declared a site area emergency, which was terminated approximately 4 hours later. Approximately 25 members of the public were temporarily evacuated from their homes, and approximately 75 persons remained sheltered in their homes for a time. Four members of the public went to the hospital. Three of the four were examined and released, while the fourth was held for observation and released the next day. This individual showed skin reddening on portions of his face and part of one arm, which indicated a hydrogen fluoride (HF) acid burn. Honeywell’s initial estimate of a release of 7 pounds of UF6 was later refined to be approximately 70 pounds. Honeywell shut the plant down and agreed to discuss corrective actions with the NRC before restarting operations to determine whether the NRC had any objection to restarting specific operations. Cause(s)—An NRC Augmented Inspection Team (AIT) and Honeywell’s Root Cause Investigation Team identified similar root and contributing causes. The Honeywell Root Cause Investigation Team provided its findings to the NRC in a meeting on February 11, 2004. Key causes were as follows: • The licensee failed to have a written procedure for an infrequent evolution and, thus, relied on the operator’s memory to perform the required actions. • The licensee’s corrective action program had not adequately corrected a previously identified lack of procedures for certain activities, the licensee had not adequately aligned staff to the need for procedures for activities. • The licensee did not have an alarm to warn operators that the system was becoming pressurized. The licensee did not have procedures or measures to respond to abnormal conditions during operations. The licensee did not have procedures or processes for documenting when equipment was not in proper working order. In addition, the AIT and Honeywell Root Cause Investigation Team identified problems in implementing the emergency plan once the licensee identified the release, including problems in communication with State and local authorities. E:\FR\FM\02MYN1.SGM 02MYN1 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices Actions Taken To Prevent Recurrence Licensee—In addition to the Root Cause Investigation Team, Honeywell chartered a Plant Engineering Team, a ‘‘Triangle of Prevention’’ Team, and a Corporate ‘‘Deep Dive’’ Team to review the facility and operations. These teams reviewed certain UF6 safety and environmental improvements, management processes, change management, mechanical integrity, and the emergency plan. As a result of these reviews, Honeywell developed a list of corrective and improvement actions to be completed before restarting operations. On March 4, 2004, Honeywell submitted a list of the actions to be taken for each phase of the restart. Honeywell has also worked with State and local authorities to improve emergency response, and the company conducted an emergency drill with local agencies on March 11, 2004. That drill identified items that needed to be improved, including use of the dedicated phone for communicating with off site authorities. Honeywell plans to improve this communication method. In addition, Honeywell is in the process of implementing other corrective and improvement actions. NRC—The NRC developed a Restart Readiness Oversight Plan to review Honeywell’s actions, including safety and emergency preparedness improvements. The NRC has reviewed actions the licensee planned to prevent recurrence. In addition, the NRC observed an emergency drill of the revised Emergency Plan and procedures. The NRC held two public meetings in Metropolis, Illinois (on March 18 and April 21, 2004) during the restart phase to inform the public of the licensee’s plans and progress and to describe the NRC’s oversight activities and results. In addition, the NRC completed inspections of the licensee’s corrective actions before the restart of licensed operations. On May 10, 2004, the NRC issued a Notice of Violation for two significant violations identified during the AIT inspection. Specifically, those violations involved (1) reconfiguration of the fluorination system without detailed instructions (which allowed a UF6 leak to occur), and (2) failure to maintain and execute various response measures in the emergency response plan. The NRC performed followup inspections specifically focused on Honeywell’s implementation of its corrective actions on June 10 and August 13, 2004. The areas inspected included plant operations, chemical safety, emergency preparedness, maintenance and surveillance, VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 management organization and controls, and operator training. The June inspection did not identify any violations, but the August inspection identified two Severity Level IV violations. Those cited violations concerned the conduct of operations that were not adequately described in written operating procedures and an inadequate evaluation of the radiological conditions associated with storage of bed material and filter fines. On September 30, 2004, the NRC held a public meeting with Honeywell to discuss the company’s progress in implementing long-term corrective actions that will ensure sustained performance improvements. Honeywell’s long-term efforts were primarily directed at procedures and training, plant material conditions, and emergency preparedness. The NRC also described the additional inspections completed since the restart of licensed operations at the site and the agency’s plan to continue increased oversight. The NRC performed an additional inspection in December 2004, and identified a violation that involved the failure of the licensee’s operations personnel to properly perform pre-fill inspections of UF6 cylinders. This failure resulted in Honeywell’s shipment of 14 cylinders with prohibited Hunt valves attached. Based upon the results of this inspection, together with those of the previous inspections, the NRC has determined that the heightened oversight of licensed activities performed at the Honeywell facilities will continue. This event is open for the purpose of this report. * * * * * 04–02 Incinerator Event at Westinghouse Columbia Fuel Fabrication Facility in Columbia, South Carolina Date and Place—Discovered on March 5, 2004; Westinghouse Columbia Fuel Fabrication Facility; Columbia, South Carolina. Nature and Probable Consequences— The licensee uses a standard industrial incinerator to reduce uraniumcontaminated process waste volume and facilitate uranium recovery from the waste. During a technical review of a proposed procedure change, the licensee determined that its incinerator off-gas system was being operated outside the approved safety basis. Samples of ash deposited at various locations in the incinerator exceeded the assumed uranium concentration for incinerator ash. The licensee immediately stopped incinerator operations and performed a complete PO 00000 Frm 00097 Fmt 4703 Sfmt 4703 22723 incinerator clean-out. The licensee determined that approximately 271 kilograms of ash at a maximum uranium concentration of approximately 30 wt% had accumulated in the incinerator’s secondary combustion chamber. The licensee had performed a criticality analysis that concluded no ash would accumulate in the secondary combustion chamber, and the maximum uranium concentration of ash in the incinerator system could not exceed 21.6 wt%. No criticality safety controls were in place to prevent the accumulation of fly-ash containing excessive uranium concentrations. Cause(s)—The licensee’s criticality safety staff failed to recognize that flyash could accumulate in the incinerator’s secondary combustion chamber, and ash uranium concentrations could exceed 21.6 wt%. Contributing factors were the failure to control incinerator operations that allowed the increased uranium concentration in the fly-ash, and failure to recognize excessive material accumulation or uranium concentration increases. Actions Taken To Prevent Recurrence Licensee—The licensee immediately stopped incinerator operations and initiated a project to prevent future material accumulations. The licensee also initiated a program to upgrade criticality safety at the plant, including assigning additional staff to the nuclear criticality safety program, improving ownership of criticality safety by production and engineering staff, improving management and ownership of change, performing a comprehensive review of existing criticality safety analyses, using the integrated safety analysis process to prioritize changes to administrative criticality safety controls, and implementing a comprehensive program throughout the plant to ensure procedure compliance. NRC—On May 13, 2004, the NRC issued Inspection Report 70–1151/ 2004–001, which described the event. On July 19, 2004, the NRC issued an Information Notice to fuel cycle licensees concerning the use of lessthan-optimal bounding assumptions in criticality safety analyses at fuel cycle facilities. On July 28, 2004, the NRC issued a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $24,000 to the licensee for failure to establish and maintain double-contingency protection in the incinerator and failure of management controls to detect the accumulation of a critical mass of fissile material in an unsafe geometry vessel. Although the normal civil penalty assessment process E:\FR\FM\02MYN1.SGM 02MYN1 22724 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices would have fully mitigated the civil penalty, the NRC exercised enforcement discretion in accordance with Section VII.A.1 of the Enforcement Policy and proposed a base civil penalty to reflect the safety significance of the issue, which resulted in a substantial increase in the likelihood of a nuclear criticality event. On October 21, 2004, the NRC conducted a management meeting with the licensee to discuss the incinerator event and its proposed corrective actions. The NRC will follow the corrective actions through the agency’s inspection and oversight programs. This event is closed for the purpose of this report. * * * * * Other NRC Licensees (Industrial Radiographers, Medical Institutions, etc.) The NRC determined that the following events which occurred at facilities, licensed or otherwise regulated by the NRC, during this reporting period were significant enough to be reported as AOs: 04–03 Iodine–125 Brachytherapy Seed Medical Event at Albert Einstein HealthCare Network in Philadelphia, Pennsylvania Date and Place—October 16, 2003 (identified on November 20, 2003); Albert Einstein HealthCare Network in Philadelphia, Pennsylvania. Nature and Probable Consequences— A patient received a permanent brachytherapy implant using iodine– 125 (I–125) seeds as treatment for prostate carcinoma on October 16, 2003. The authorized user prescribed a dose of 145 Gy (14,500 rads) to the prostate gland. The implant was performed under ultrasound guidance, and 89 sources were implanted as prescribed in the written directive. On November 17, 2003, the patient returned for a routine postoperative computerized tomography (CT) scan. On November 20, 2003, a review of the scan revealed that many of the seeds were not located in the prostate as intended, but were in adjacent tissue where they were ineffective during treatment. As a result, the prostate gland received an inadequate dose of 18.6 Gy (1,860 rads), while the adjacent tissue received a dose of approximately 115 Gy (11,500 rads). An NRC medical consultant determined that the probable consequences to the patient would be comparable to the effects of external beam radiation treatment for prostate cancer and would not cause further damage to the patient. The patient and the patient’s referring physician were notified of the event. VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 Cause(s)—The licensee determined that this medical event was caused by human error, the most likely being the misidentification of the prostate gland on the intra-operative ultrasound. Other possible causes include shifting of the needle grid in the patient on the operating room table or the suction of the seeds into the needle tract after the removal of the individual needles from the patient. Actions Taken To Prevent Recurrence Licensee—The licensee’s corrective actions for future prostate brachytherapy treatments include new requirements that an outside radiation oncologist with expertise in prostate brachytherapy will monitor authorized users, and an experienced prostate brachytherapist will observe authorized users as they perform prostate implant procedures. In addition, the licensee implemented revised procedures, including performing a pre-operative CT scan; reviewing pre-planned ultrasound studies prior to, during, and after the procedure; and reviewing postoperative pelvic x-rays within 1 day of the procedure. Furthermore, the Radiation Safety Committee will review all forms, documents, education, and oversight associated with the permanent prostate implant program, and will make recommendations or amendments, as necessary, to reflect programmatic changes. NRC—The NRC staff conducted a special safety inspection on December 5, 2003, and did not identify any violations associated with the licensee’s actions. The NRC also reviewed the licensee’s current prostate implant program, and concluded that 12 other I– 125 prostate implants had been completed without incident. This event is closed for the purpose of this report. * * * * * 04–04 Diagnostic Medical Event at William Beaumont Hospital in Royal Oak, Michigan Date and Place—June 8, 2004; William Beaumont Hospital; Royal Oak, Michigan. Nature and Probable Consequences— The licensee reported that a patient was prescribed a dose of 0.37 megabecquerels (MBq) [10 microcuries (µCi)] of I–131 for a thyroid uptake procedure, but instead received 33.86 MBq (915 µCi) of I–131. The pipette used to prepare I–131 therapy dosages earlier in the day was inadvertently used to draw the 0.37 MBq (10 µCi) I– 131 uptake dosage. The technician properly disposed of the I–131 uptake dosage after identifying the error. PO 00000 Frm 00098 Fmt 4703 Sfmt 4703 The technician then obtained the ‘‘uptake’’ pipette and prepared a second dosage from the I–131 bulk uptake solution. However, the ‘‘uptake’’ pipette had inadvertently been switched with the ‘‘therapy’’ pipette used earlier. This may have occurred because both the thyroid ‘‘uptake’’ pipette and the ‘‘therapy’’ pipette had illegible labels. As a result, the second dosage contained 0.074 MBq (2 µCi) of I–131 remaining from the earlier therapy administrations and the newly drawn I–131 prepared for the thyroid uptake. The total activity for the second dosage measured 33.86 MBq (915 µCi). The technician focused on drawing the calculated volume required to obtain the prescribed activity, rather than the radioactive activity measured in the dose calibrator and interpreted the ‘‘0.915 millicuries (mCi)’’ displayed on the dose calibrator as ‘‘9.15 µCi.’’ The technician electronically transferred the dosage measurement from the dose calibrator to a dosage label. A second technician administered the dosage to the patient. Assuming a 55% uptake, the absorbed dose to the patient’s thyroid was 26.75 Gy (2,675 rads) with an effective dose equivalent of 0.81 Gy (81 rads). The patient and referring physician were notified of the medical event on June 9, 2004. The licensee indicated that the additional dosage administered to the patient would not result in any increased risk or biological effect to the patient. Cause(s)—This event was caused by human error. The nuclear medicine technologist who drew the dose misinterpreted the reading on the dose calibrator, and the technician who administered the dose did not verify the dose before administration. Actions Taken To Prevent Recurrence Licensee—The licensee implemented a requirement to use a new pipette each time an I–131 uptake dose is prepared, reprogrammed the computer to accept uptake dose activity rather than volume and stopped the computer from printing a dose label when the activity is not within the established range. The licensee also trained the radiopharmacy staff not to override the computer’s failsafe mechanisms, and retrained the nuclear medicine technologist in the process for dose verification prior to administration. NRC—The NRC staff conducted a special safety inspection on June 10, 2004. Then, on September 14, 2004, the NRC issued a Notice of Violation for a significant violation involving the administration of a dosage of liquid I– 131 to a patient for a thyroid uptake study that was approximately 90 times E:\FR\FM\02MYN1.SGM 02MYN1 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices larger than the 10-µCi dosage prescribed by the authorized user physician. This event is closed for the purpose of this report. * * * * * Agreement State Licensees The NRC determined that the following events, which occurred at Agreement State licensed facilities during this reporting period, were significant enough for reporting as AOs: AS 04–01 I–125 Brachytherapy Seed Medical Event at Central Arkansas Radiation Therapy Institute in Conway, Arkansas Date and Place—December 4, 2003; Central Arkansas Radiation Therapy Institute; Conway, Arkansas. Nature and Probable Consequences— The licensee reported that a patient received a radiation dose to an unintended area during an I–125 prostate-seed implant procedure. The patient was prescribed treatment with 122 I–125 seeds, with each seed containing an activity of 13.3 MBq (0.36 mCi). During the patient’s post-implant CT scan on December 18, 2003, the licensee discovered that the seeds had been implanted 2 centimeters (cm) too low and missed treating the upper portion of the prostate gland. As a result, 68 cm3 of adjacent tissue received the prescribed dose of 144 Gy (14,400 rads). The licensee reported that the adjacent tissue should not be affected adversely by the dose delivered by the seeds. The licensee administered additional treatment to deliver the intended dose to the upper 2 cm of the prostate gland. The licensee notified the patient and the patient’s referring physician of the event. Cause(s)—This event was attributed to human error in that the treatment site was not verified. Actions Taken To Prevent Recurrence Licensee—The licensee wrote a new procedure to implement the use of fluoroscopic guidance to ensure the correct placement of seeds. State Agency—The State has reviewed and accepted the licensee’s corrective actions. This event is closed for the purpose of this report * * * * *. AS 04–02 Dose to Fetus at Hillcrest Hospital of Mayfield Heights, Ohio Date and Place—November 20, 2003, Hillcrest Hospital; Mayfield Heights, Ohio. Nature and Probable Consequences— The Ohio Bureau of Radiation Protection reported that a 19-year-old VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 female patient was administered 5.18 gigabequerels (GBq) (140 mCi) of I–131 as prescribed for thyroid carcinoma. At the time, the patient was unaware that she was pregnant and she completed the required forms indicating that she was not pregnant. However, on December 5, 8, and 11, 2003, quantitative tests confirmed that the patient was pregnant. The licensee provided the results to the patient’s endocrinologist, who recommended performing a fetal dose calculation. The licensee was notified and its consultant informed the endocrinologist that the fetus would have received a whole body dose of 0.19 Gy (19.8 rads). The endocrinologist sent the results to the Center for Human Genetics at the University Hospital in Cleveland, Ohio, where an assessment determined that the pregnancy could safely continue. Cause(s)—This event was caused by human error. At the time of the administration, the patient was unaware of her pregnancy status and completed forms indicating that she was not pregnant. Actions Taken To Prevent Recurrence Licensee—The licensee has implemented pregnancy testing for patients of child bearing age, who receive radiation therapy. State Agency—The Ohio Bureau of Radiation Protection was notified of this event on January 16, 2004, and performed a special inspection on January 22, 2004. The State found the licensee’s corrective actions adequate to prevent recurrence. This event is closed for the purpose of this report. * * * * * AS 04–03 High Dose Rate Afterloader Medical Event at New Orleans Cancer Institute at Memorial Medical Center, Louisiana Date and Place—March 31, 2004; New Orleans Cancer Institute; New Orleans, Louisiana. Nature and Probable Consequences— A cancer patient undergoing therapeutic radiation treatment for prostate cancer received 18 Gy (1,800 rads) to the wrong treatment site. This error occurred using a high dose rate (HDR) afterloader device with a radioactive source containing 270.7 GBq (7.32 Ci) of Ir– 192. The event occurred after the dosimetrist made an error while inputting data into the afterloader’s dosimetry software program. Although the dosimetrist appropriately clicked the ‘‘catheter tip’’ selection, the dosimetrist did not highlight and choose ‘‘catheter tip.’’ Therefore, the computer cursor stayed on the ‘‘connector end’’ PO 00000 Frm 00099 Fmt 4703 Sfmt 4703 22725 selection. This resulted in a 2-cm positioning error, which caused the source to stop short of the target so that the total prescribed dose was not delivered. The patient was informed of the event, and the remaining dose was delivered by external beam therapy. According to the Radiation Oncologist, no detrimental effects are expected. The patient was self-referred for the therapeutic treatment. Cause(s)—This event was attributed to operator error. Actions Taken To Prevent Recurrence Actions taken to prevent recurrence include implementing procedures to add a visual check and documentation that the treatment plan was administered with the source position calculated from the tip end of the catheter or needle. This procedure will be added to the pre-treatment checklist, which is performed and signed by the radiation oncologist, physicist, and dosimetrist. The checklist will be performed prior to initial treatment and at treatment plan changes, and will be part of the patients’ permanent records. Also, the licensee contacted the device’s manufacturer regarding the confusion associated with the default orientation in the software program, and requested an adjustment to the program. The manufacturer stated that this could not be done at this time, but is discussing the issue. The manufacturer offered additional training to the licensee’s employees, and the licensee is sending its employees to the training. State Agency—The State accepted the licensee’s implementation of new procedures and its corrective actions as appropriate. This event is closed for the purpose of this report. * * * * * AS 04–04 Diagnostic Medical Event at Northeast Alabama Regional Medical Center, Alabama Date and Place—August 10, 2004; Northeast Alabama Regional Medical Center; Montgomery, Alabama. Nature and Probable Consequences— A patient received 111 MBq (3,000 µCi) of I–131 instead of the prescribed dose of 0.93 MBq (25 µCi). The licensee discovered the event on August 12, 2004, when the patient returned for the whole body scan 48 hours later. The referring physician had requested a diagnostic I–131 scan to assess a thyroid nodule, which requires 0.93 MBq (25 µCi). The technologist misunderstood the order by assuming that the referring physician wanted a whole body scan to assess thyroid cancer, and administered 111 MBq (3,000 µCi) of I–131 without E:\FR\FM\02MYN1.SGM 02MYN1 22726 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices requesting clarification or approval from the authorized users. Two authorized users determined that the patient could become hypothyroid. Therefore, patient followup assessments included thyroid profiles and thyroid uptakes to determine thyroid function. The patient and the referring physician were informed of the event. Cause(s)—This event was attributed to human error. The technologist misunderstood the treatment ordered by the referring physician and failed to verify the written directive. Actions Taken To Prevent Recurrence Licensee—The licensee implemented corrective measures to ensure that authorized users approve all procedures involving the administration of radiopharmaceuticals and re-instructed nuclear medicine personnel. State Agency—The State conducted an inspection. This event is closed for the purpose of this report. * * * * * AS 04–05 Occupational Exposure at Palmetto Health and Baptist Hospital in Columbia, South Carolina Date and Place—March 17, 2004; Palmetto Health and Baptist Hospital; Columbia, South Carolina. Nature and Probable Consequences— The licensee reported that a pharmacist trainee received an extremity exposure resulting in a shallow dose equivalent to the hand of 7,420 mSv (742 rem), a deep dose equivalent to the hand of 70 mSv (7.02 rem), and a thyroid dose of 0.9 mSv (0.09 rem). The exposures occurred when a spill took place while compounding I–131 from a vial. The pharmacist trainee cleaned up the area, decontaminated his skin, and reported the spill to the imaging manager the following day. The imaging manager conducted a second survey of the area, which showed that no contamination remained from the spill. The pharmacist trainee completed a spill report but did not reveal his contamination in the report. The pharmacist trainee left for vacation and 11 days later, after his return, informed the Radiation Safety Officer (RSO) that his forearm had been contaminated during the I–131 spill. Immediate actions were taken to determine whether any contamination still remained on his arm. Elevated levels were discovered on his right forearm and left fingertips. The appropriate hospital/nuclear medicine personnel were notified. The pharmacist trainee was suspended from any and all duties involving radioactive material. Cause(s)—This event occurred as a result of human error and failure to VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 follow established procedures. An initial crimp failure on the vial may also have contributed to the spill. Actions Taken To Prevent Recurrence Licensee—The licensee retrained all staff in spill procedures, emphasizing proper notification of supervisors. Additionally, at the prompting of the licensee, the vial supplier reevaluated the process of ensuring that each crimp is acceptable for shipment, although the supplier believed it was more likely an isolated incident. State Agency—The State agency conducted inspections and cited the licensee for violations of regulations for controlling radiation. * * * * * AS 04–06 Gamma Stereotactic Radiosurgery (Gamma Knife) Medical Event at Radiosurgical Center of Memphis in Memphis, Tennessee Date and Place—January 24, 2003; Radiosurgical Center of Memphis; Memphis, Tennessee. This event was not determined to be an AO until the preparation of the FY2004 report. Nature and Probable Consequences— The licensee reported that a patient received 27 Gy (2,700 rads) to a brain metastasis instead of the intended 18 Gy (1,800 rads) during gamma knife treatment. The physicist did not determine that an error had occurred until the treatment was complete. The RSO determined that one of the four brain metastases received greater than the prescribed dose. The other three brain metastases received the prescribed dose. The tumor that received the incorrect dose was at the periphery of the brain next to the skull in a noncritical area so that much of the extra dose was delivered to the space between the brain and the skull. The cause of the incident was that a 14-millimeter (mm) (.55-inch) collimator helmet was used instead of the prescribed 8-mm (.31 inch) collimator helmet. The personnel setting up the treatment neglected to change the helmet. The tumor that received the unintended dose was located at the periphery of the brain, adjacent to the skull. Because most of the unintended dose was delivered to a non-critical space, between the brain and skull, the additional radiation exposure should have no significant effect on the patient. The referring physician was notified of the event and informed the patient’s family of the unintended dose. Cause(s)—The cause was human error, in that the event resulted from use of the wrong collimator helmet. PO 00000 Frm 00100 Fmt 4703 Sfmt 4703 Actions Taken To Prevent Recurrence Licensee—The licensee established a new procedure to require the physician, physicist, and nurse to sign off on the treatment time, helmet size, and position before each shot. Also, new labels identifying the size of the helmet were attached to each of the four helmets. These labels can be seen by personnel via the TV monitor located at the control panel outside the treatment room. The physician will verify the correct size before the control panel button is pushed to start the treatment. State Agency—The State reviewed and approved the licensee’s new procedures. * * * * * AS 04–07 Strontium-90 Eye Applicator Brachytherapy Medical Event at St. Francis Hospital in Memphis, Tennessee Date and Place—March 25, 2004; St. Francis Hospital; Memphis, Tennessee. Nature and Probable Consequences— A 79-year-old patient was prescribed radiation treatment for pterygium (an eye abnormality). The patient was to receive 20 Gy (2,000 rads), but instead received 70 Gy (7,059 rads). The prescribed dose was to be administered via a Sr-90 radioactive source with an activity of 3.7 GBq (100 mCi) for a duration of 42.5 seconds. However, the manual timer was incapable of being set for fractions of a second and interpreted the entry to be 4 minutes and 25 seconds. During the treatment, the physician questioned the treatment time and terminated the treatment after 2 minutes and 30 seconds. The Radiation Oncologist concluded that the maximum possible dose delivered to the sclera was well below the sclera tolerance dose and that the optic nerve and retina did not receive any meaningful dose. The patient and the referring physician were notified of the event. Cause(s)—The wrong treatment time was programmed for the patient’s eye treatment. Actions Taken To Prevent Recurrence Licensee—The licensee updated its procedures, which require use of an additional person to operate a second timer during brachytherapy eye treatment. State Agency—The Tennessee Department of Radiological Health conducted an onsite inspection on March 29, 2004. The State investigated, reviewed, and approved the licensee’s new procedures. This event is considered closed for the purpose of this report. * * * * * E:\FR\FM\02MYN1.SGM 02MYN1 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices AS 04–08 Therapeutic Medical Event at Southern Regional Medical Center in Riverdale, Georgia AS 04–09 Intravascular Brachytherapy Medical Event at Ireland Cancer Center in Middleburg Heights, Ohio. Date and Place—July 1, 2004; Southern Regional Medical Center; Riverdale, Georgia. Nature and Probable Consequences— The licensee informed the Georgia Department of Natural Resources (GDNR) that a patient received 3.7 GBq (100 mCi) of I–131 instead of the prescribed dose of 0.64 GBq (17.3 mCi). Three patients were scheduled for I–131 treatments on the same day. An inpatient was scheduled to receive 3.7 GBq (100 mCi), and two outpatients were scheduled to receive less than 1.2 GBq (33 mCi). One of the outpatients was mistakenly injected with the 3.7 GBq (100 mCi) dose intended for the inpatient and was also allowed to leave the facility without receiving proper instructions. The licensee did not discover the error until after the patient had left the facility with her children. The authorized user who signed the written directive was at the facility when the dose was administered. The temporary RSO was at South Fulton Hospital, but was notified of the event. The patient and referring physician were immediately notified of the event by the licensee. The GDNR received a report from the licensee’s medical physicist consultant estimating the dose to the patient’s children was 0.5 mSv (0.05 rem), with a maximum possible dose of 1.0 mSv (0.1 rem). The radiation should not have any effects on the patient’s children or other individuals. The medical significance to the patient is the possibility of developing hypothyroidism which would require thyroid medication. Cause(s)—This event was attributed to human error. The wrong patient was administered a therapeutic dose of I– 131 that was prescribed for someone else. Date and Place—December 22, 2003; Ireland Cancer Center; Middleburg Heights, Ohio. Nature and Probable Consequences— The licensee reported that a patient received a radiation dose to an unintended site 3 cm proximal to the prescribed treatment site during an intravascular brachytherapy (IVB) treatment procedure. The dose delivered to the unintended site was approximately 18.40 Gy (1,840 rads). The event involved an IVB device that used a 3.5-mm catheter and a source train that contained Sr-90 with an activity of 2.0 GBq (53.8 mCi). The source train traveled to a location approximately 3 cm proximal to the intended treatment site. It was determined that there was a kink in the delivery catheter, which kept the source train from traveling to the correct site. The kink was not substantial enough to affect the flow of sterile water used to send and retrieve the source train. The kink was discovered the following day during medical physics quality checks. The referring physician and patient were notified of the event. According to the licensee, no adverse effects are expected. Cause(s)—The cause of the event was determined to be a kink in the delivery catheter, which kept the source train from traveling to the correct site. Actions Taken To Prevent Recurrence Licensee—The licensee discussed the incident with all technicians who prepare and administer I–131, revised nuclear medicine protocols pertaining to the therapeutic use of I–131 and patient instructions, and revised procedures to incorporate better practices to prevent this type of error from recurring. State Agency—The State agency reviewed and approved the corrective actions that the licensee implemented to prevent recurrence. This event is considered closed for the purpose of this report. * * * * * VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 Actions Taken To Prevent Recurrence Licensee—Corrective actions incorporated by the licensee included additional films taken during procedures to verify the placement of the catheter. When there is any doubt of the placement of the catheter, the treatment will be aborted. The treatment team will then evaluate whether to attempt treatment with a different catheter. State Agency—The Ohio Department of Health conducted an investigation, reviewed the licensee’s corrective actions, and found them adequate to prevent recurrence. This event is considered closed for the purpose of this report. * * * * * AS 04–10 Intravascular Brachytherapy Medical Event at Swedish Medical Center in Seattle, Washington Date and Place—November 18, 2003; Swedish Medical Center; Seattle, Washington. Nature and Probable Consequences— A patient undergoing an intravascular brachytherapy (IVB) treatment for PO 00000 Frm 00101 Fmt 4703 Sfmt 4703 22727 coronary restenosis received 13.78 Gy (1,378 rads) to an unintended site (healthy tissue). The licensee reported that the source train was partially inserted into a small artery, and the routing did not follow a direct path. When the difficulty occurred, the source train had been partially inserted 65 mm proximal to the intended site. The source train contained a total activity of 2.91 GBq (78.56 mCi). A 143-second exposure time elapsed before the cardiologist withdrew the source train, even though the licensee’s procedure requires sources to be immediately withdrawn once a problem occurs. The delay occurred as the cardiologist first worked to fully insert the source train and then discussed correcting the problem with the oncologist. The catheter was examined, and there were no kinks or bends. It was determined that there were no failures of the IVB device. It was suspected that the pressure from the artery and the tortuous route to the site caused a contraction of a portion of the catheter and resulted in the seeds becoming stuck at a particular location. The cardiologist was suspended from licensed activities until the details of the event were fully understood. According to the licensee, no adverse health effects are expected. The patient and the patient’s referring physician were notified of the event. Cause or Causes—It is suspected that the pressure from the small artery and the tortuous route to the site caused a contraction of a portion of the source train and resulted in the seeds becoming stuck at a particular location. Actions Taken To Prevent Recurrence Licensee—Corrective actions included reemphasizing the importance of adhering to established procedures and protocols before administering radiopharmaceuticals, and ensuring that all staff completed refresher training. State Agency—The State reviewed and approved the corrective actions taken by the licensee and will follow-up at the next inspection. This event is closed for the purpose of this report. * * * * * AS 04–11 Diagnostic Medical Event at Swedish Medical Center in Seattle, Washington Date and Place—September, 24, 2004; Swedish Medical Center; Seattle, Washington. Nature and Probable Consequences— The licensee reported that a patient received 190.9 MBq (5.16 mCi) of I–131, instead of the prescribed 74 MBq (2 mCi) for a post thyroid treatment followup scan. The prescribing physician E:\FR\FM\02MYN1.SGM 02MYN1 22728 Federal Register / Vol. 70, No. 83 / Monday, May 2, 2005 / Notices realized that the error occurred on September 27, 2004, when the patient underwent the scan. A viable follow-up scan was performed even though the error occurred. The referring physician notified the patient of the error on September 27, 2004. The nuclear medicine physician indicated there would be no negative health effects from this administration. Cause or Causes—The licensee stated that human error led to procedural checks not being performed prior to the administration. Actions Taken To Prevent Recurrence Licensee—Corrective actions included re-emphasis on the importance of adhering to established procedures and protocols prior to the administration of radiopharmaceuticals and the completion of staff refresher training. State Agency—The State reviewed and approved the corrective actions taken by the licensee and will follow-up at the next inspection. This event is considered closed for the purpose of this report. * * * * * AS 04–12 Therapeutic Medical Event at University of California at Los Angeles Harbor Medical Center in Torrance, California Date and Place—June 7, 2002; Los Angeles County Harbor University of California at Los Angeles (UCLA) Medical Center; Torrance, California. This event was not identified as an AO until the preparation of the FY 2004 report. Nature and Probable Consequences— A patient receiving treatment for thyroid ablation was administered a dose of 4.74 GBq (128 mCi) of I–131 instead of the prescribed dose of 1.18 GBq (32 mCi) of I–131. On June 7, 2002, five patients were scheduled to be treated with I–131. Five vials containing I–131 arrived from the radiopharmacy and were properly labeled with the patients’ names. The nuclear medicine technologist incorrectly thought that the name on the 4.74 GBq (128mCi) vial did not match any of the patient’s names scheduled for treatment that day. Assuming that this vial was incorrectly labeled, the 4.74 GBq (128 mCi) dosage was administered to the patient for whom the technologist thought the dose was intended. However, the technologist failed to verify whether any of the remaining four dosages were labeled for that patient. In fact, a vial was correctly labeled as prepared for that patient. The authorized user was present during the administration to supervise the administration of the VerDate jul<14>2003 19:05 Apr 29, 2005 Jkt 205001 radiopharmaceutical, and to verify that the correct radiopharmaceutical and dosage were administered. The authorized user did not perform an independent verification, but instead assumed that the nuclear medicine technologist had verified that the dosage was correct. The error was discovered about 5 hours later, when the patient scheduled to receive the 4.74 GBq (128 mCi) dosage arrived at the medical center for treatment. The patient and the referring physician were notified. The authorized user went to the home of the patient who received the inadvertent administration and verified that appropriate radiation safety precautions were in place. The patient’s treatment plans were modified to accommodate the larger dosage. The authorized user stated that the dosage was intended to ablate the thyroid and render the patient hypothyroid, and that was accomplished with the larger dose. He further stated the patient is doing well, with no complications. Cause(s)—This medical event was caused by human error which resulted in the licensee’s failure to follow proper policies and procedures and verify the prescribed dosage for a specific patient. Actions Taken To Prevent Recurrence Licensee—The licensee re-instructed all nuclear medicine personnel on the importance of following the division’s policies and procedures and the use of a third party to check the prescription dose and patient identification before administration. Additionally, the RSO will review all I–131 therapy documents and administrations. State Agency—The State cited the licensee for failure to provide written notification to the referring physician and the patient within 15 days after the occurrence of the medical event. The State has reviewed and approved the licensee’s corrective actions. * * * * * AS 04–13 Diagnostic Medical Event at University Hospital in Cincinnati, Ohio Date and Place—March 10, 2004; University Hospital; Cincinnati, Ohio. Nature and Probable Consequences— The licensee reported that a patient was given 74 MBq (2,000–Ci) of I–131 for a thyroid cancer work-up instead of the prescribed dose of 7.4 MBq (200–Ci) of I–123 for a thyroid uptake scan. The patient scheduled to receive the I–123 dose responded affirmatively to being the patient that was to receive the I–131 dose. The technologist did not follow procedures regarding proper identification of the patient, which requires two separate methods for verifying patient identification. A PO 00000 Frm 00102 Fmt 4703 Sfmt 4703 follow-up scan revealed the patient does have hypothyroidism, and as a result, the 74 MBq (2,000–Ci) of I–131 would have been prescribed based on the scan results. The referring physician and patient were notified. No adverse health effects are expected. Cause or Causes—The technologist failed to follow established procedures. Actions Taken to Prevent Recurrence Licensee—The licensee disciplined the technologist in accordance with hospital policy and reiterated to all technologists the need to thoroughly check patient identification using two approved methods. Additionally, the Radiation Safety Committee modified the Quality Management Program to require a photo as one method of verifying patient identification. State Agency—The Ohio Department of Health conducted an investigation of the event on May 11, 2004, and reviewed the licensee’s corrective actions. The State found the licensee’s corrective actions adequate to prevent a recurrence of the event. This event is closed for the purpose of this report. Dated at Rockville, Maryland this 18th day of April 2005. For the Nuclear Regulatory Commission Annette L. Vietti-Cook, Secretary of the Commission.

NUCLEAR REGULATORY COMMISSION


Report to Congress on Abnormal Occurrences Fiscal Year 2004 
Dissemination of Information

    Section 208 of the Energy Reorganization Act of 1974 (Pub. L. 93-
438) defines an abnormal occurrence (AO) as an unscheduled incident or 
event which the U.S. Nuclear Regulatory Commission (NRC) determines to 
be significant from the standpoint of public health or safety. The 
Federal Reports Elimination and Sunset Act of 1995 (Pub. L. 104-66) 
requires that AOs be reported to Congress annually. During fiscal year 
2004, 17 events that occurred at facilities licensed or otherwise 
regulated by the NRC and/or Agreements States were determined to be 
AOs. The report describes four events at facilities licensed by the 
NRC. One event involved a uranium hexafluoride release at a fuel cycle 
facility. Another event, also at a fuel cycle facility, revealed 
excessive uranium concentrations found in ash deposits in various 
locations in an incinerator. A third event involved a patient 
undergoing therapeutic brachytherapy treatment. The fourth event 
involved an unintentional excessive dose of sodium iodide (I-131) 
administered to a patient. The report also addresses 13 AOs at 
facilities licensed by Agreement States. [Agreement States are those 
States that have entered into formal agreements with the NRC pursuant 
to Section 274 of the Atomic Energy Act (AEA) to regulate certain 
quantities of AEA licensed material at facilities located within their 
borders.] Currently, there are 33 Agreement States. During FY 2004, the 
NRC received notification of 13 events that occurred at Agreement 
State-licensed facilities, including 8 therapeutic medical events, 3 
diagnostic medical events, 1 event involving an unintentional dose of 
I-131 to an embryo/fetus, and 1 event involving an extremity 
overexposure to a radiopharmacy trainee. As required by Section 208, 
the discussion for each event includes the date and place, the nature 
and probable consequences, the cause or causes, and the action taken to 
prevent recurrence. Each event is also being described in NUREG-0090, 
Vol. 27, ``Report to Congress on Abnormal Occurrences, Fiscal Year 
2004.'' This report will be available electronically at the NRC Web 
site https://www.nrc.gov/reading-rm/doc-collections/nuregs/ staff/.

Nuclear Power Plants

    During this period, no events occurred at U.S. nuclear power plants 
that were significant enough to be reported as AOs.

Fuel Cycle Facilities

    (Other Than Nuclear Power Plants)
    During this period, two events occurred at U.S. fuel cycle 
facilities that were significant enough to be reported as AOs.

04-01 Uranium Hexafluoride Release at Honeywell Speciality Chemicals, 
Inc. in Metropolis, Illinois

    Date and Place--December 22, 2003; Honeywell International, Inc., 
Honeywell Specialty Chemicals, Metropolis, Illinois.
    Nature and Probable Consequences--On December 22, 2003, a uranium 
hexafluoride (UF6) release occurred from one of the plant's 
chemical process lines. The release occurred due to improper valve 
alignment which caused inadvertent pressurization of the system. The 
licensee did not have a written procedure for a process that was 
performed infrequently and relied on the operator's memory to perform 
the required actions. The release lasted approximately 40 minutes. The 
licensee observed a visible cloud crossing the site boundary and 
declared a site area emergency, which was terminated approximately 4 
hours later. Approximately 25 members of the public were temporarily 
evacuated from their homes, and approximately 75 persons remained 
sheltered in their homes for a time. Four members of the public went to 
the hospital. Three of the four were examined and released, while the 
fourth was held for observation and released the next day.
    This individual showed skin reddening on portions of his face and 
part of one arm, which indicated a hydrogen fluoride (HF) acid burn. 
Honeywell's initial estimate of a release of 7 pounds of UF6 
was later refined to be approximately 70 pounds. Honeywell shut the 
plant down and agreed to discuss corrective actions with the NRC before 
restarting operations to determine whether the NRC had any objection to 
restarting specific operations.
    Cause(s)--An NRC Augmented Inspection Team (AIT) and Honeywell's 
Root Cause Investigation Team identified similar root and contributing 
causes. The Honeywell Root Cause Investigation Team provided its 
findings to the NRC in a meeting on February 11, 2004.
    Key causes were as follows:
     The licensee failed to have a written procedure for an 
infrequent evolution and, thus, relied on the operator's memory to 
perform the required actions.
     The licensee's corrective action program had not 
adequately corrected a previously identified lack of procedures for 
certain activities, the licensee had not adequately aligned staff to 
the need for procedures for activities.
     The licensee did not have an alarm to warn operators that 
the system was becoming pressurized. The licensee did not have 
procedures or measures to respond to abnormal conditions during 
operations. The licensee did not have procedures or processes for 
documenting when equipment was not in proper working order.
    In addition, the AIT and Honeywell Root Cause Investigation Team 
identified problems in implementing the emergency plan once the 
licensee identified the release, including problems in communication 
with State and local authorities.

[[Page 22723]]

Actions Taken To Prevent Recurrence
    Licensee--In addition to the Root Cause Investigation Team, 
Honeywell chartered a Plant Engineering Team, a ``Triangle of 
Prevention'' Team, and a Corporate ``Deep Dive'' Team to review the 
facility and operations. These teams reviewed certain UF6 
safety and environmental improvements, management processes, change 
management, mechanical integrity, and the emergency plan. As a result 
of these reviews, Honeywell developed a list of corrective and 
improvement actions to be completed before restarting operations. On 
March 4, 2004, Honeywell submitted a list of the actions to be taken 
for each phase of the restart. Honeywell has also worked with State and 
local authorities to improve emergency response, and the company 
conducted an emergency drill with local agencies on March 11, 2004. 
That drill identified items that needed to be improved, including use 
of the dedicated phone for communicating with off site authorities. 
Honeywell plans to improve this communication method. In addition, 
Honeywell is in the process of implementing other corrective and 
improvement actions.
    NRC--The NRC developed a Restart Readiness Oversight Plan to review 
Honeywell's actions, including safety and emergency preparedness 
improvements. The NRC has reviewed actions the licensee planned to 
prevent recurrence. In addition, the NRC observed an emergency drill of 
the revised Emergency Plan and procedures.
    The NRC held two public meetings in Metropolis, Illinois (on March 
18 and April 21, 2004) during the restart phase to inform the public of 
the licensee's plans and progress and to describe the NRC's oversight 
activities and results. In addition, the NRC completed inspections of 
the licensee's corrective actions before the restart of licensed 
operations. On May 10, 2004, the NRC issued a Notice of Violation for 
two significant violations identified during the AIT inspection. 
Specifically, those violations involved (1) reconfiguration of the 
fluorination system without detailed instructions (which allowed a 
UF6 leak to occur), and (2) failure to maintain and execute 
various response measures in the emergency response plan.
    The NRC performed followup inspections specifically focused on 
Honeywell's implementation of its corrective actions on June 10 and 
August 13, 2004. The areas inspected included plant operations, 
chemical safety, emergency preparedness, maintenance and surveillance, 
management organization and controls, and operator training. The June 
inspection did not identify any violations, but the August inspection 
identified two Severity Level IV violations. Those cited violations 
concerned the conduct of operations that were not adequately described 
in written operating procedures and an inadequate evaluation of the 
radiological conditions associated with storage of bed material and 
filter fines.
    On September 30, 2004, the NRC held a public meeting with Honeywell 
to discuss the company's progress in implementing long-term corrective 
actions that will ensure sustained performance improvements. 
Honeywell's long-term efforts were primarily directed at procedures and 
training, plant material conditions, and emergency preparedness. The 
NRC also described the additional inspections completed since the 
restart of licensed operations at the site and the agency's plan to 
continue increased oversight.
    The NRC performed an additional inspection in December 2004, and 
identified a violation that involved the failure of the licensee's 
operations personnel to properly perform pre-fill inspections of 
UF6 cylinders. This failure resulted in Honeywell's shipment 
of 14 cylinders with prohibited Hunt valves attached. Based upon the 
results of this inspection, together with those of the previous 
inspections, the NRC has determined that the heightened oversight of 
licensed activities performed at the Honeywell facilities will 
continue.
    This event is open for the purpose of this report.

04-02 Incinerator Event at Westinghouse Columbia Fuel Fabrication 
Facility in Columbia, South Carolina

    Date and Place--Discovered on March 5, 2004; Westinghouse Columbia 
Fuel Fabrication Facility; Columbia, South Carolina.
    Nature and Probable Consequences--The licensee uses a standard 
industrial incinerator to reduce uranium-contaminated process waste 
volume and facilitate uranium recovery from the waste. During a 
technical review of a proposed procedure change, the licensee 
determined that its incinerator off-gas system was being operated 
outside the approved safety basis. Samples of ash deposited at various 
locations in the incinerator exceeded the assumed uranium concentration 
for incinerator ash. The licensee immediately stopped incinerator 
operations and performed a complete incinerator clean-out. The licensee 
determined that approximately 271 kilograms of ash at a maximum uranium 
concentration of approximately 30 wt% had accumulated in the 
incinerator's secondary combustion chamber. The licensee had performed 
a criticality analysis that concluded no ash would accumulate in the 
secondary combustion chamber, and the maximum uranium concentration of 
ash in the incinerator system could not exceed 21.6 wt%. No criticality 
safety controls were in place to prevent the accumulation of fly-ash 
containing excessive uranium concentrations.
    Cause(s)--The licensee's criticality safety staff failed to 
recognize that fly-ash could accumulate in the incinerator's secondary 
combustion chamber, and ash uranium concentrations could exceed 21.6 
wt%. Contributing factors were the failure to control incinerator 
operations that allowed the increased uranium concentration in the fly-
ash, and failure to recognize excessive material accumulation or 
uranium concentration increases.
Actions Taken To Prevent Recurrence
    Licensee--The licensee immediately stopped incinerator operations 
and initiated a project to prevent future material accumulations. The 
licensee also initiated a program to upgrade criticality safety at the 
plant, including assigning additional staff to the nuclear criticality 
safety program, improving ownership of criticality safety by production 
and engineering staff, improving management and ownership of change, 
performing a comprehensive review of existing criticality safety 
analyses, using the integrated safety analysis process to prioritize 
changes to administrative criticality safety controls, and implementing 
a comprehensive program throughout the plant to ensure procedure 
compliance.
    NRC--On May 13, 2004, the NRC issued Inspection Report 70-1151/
2004-001, which described the event. On July 19, 2004, the NRC issued 
an Information Notice to fuel cycle licensees concerning the use of 
less-than-optimal bounding assumptions in criticality safety analyses 
at fuel cycle facilities. On July 28, 2004, the NRC issued a Notice of 
Violation and Proposed Imposition of Civil Penalty in the amount of 
$24,000 to the licensee for failure to establish and maintain double-
contingency protection in the incinerator and failure of management 
controls to detect the accumulation of a critical mass of fissile 
material in an unsafe geometry vessel. Although the normal civil 
penalty assessment process

[[Page 22724]]

would have fully mitigated the civil penalty, the NRC exercised 
enforcement discretion in accordance with Section VII.A.1 of the 
Enforcement Policy and proposed a base civil penalty to reflect the 
safety significance of the issue, which resulted in a substantial 
increase in the likelihood of a nuclear criticality event. On October 
21, 2004, the NRC conducted a management meeting with the licensee to 
discuss the incinerator event and its proposed corrective actions. The 
NRC will follow the corrective actions through the agency's inspection 
and oversight programs.
    This event is closed for the purpose of this report.

Other NRC Licensees (Industrial Radiographers, Medical Institutions, 
etc.)

    The NRC determined that the following events which occurred at 
facilities, licensed or otherwise regulated by the NRC, during this 
reporting period were significant enough to be reported as AOs:

04-03 Iodine-125 Brachytherapy Seed Medical Event at Albert Einstein 
HealthCare Network in Philadelphia, Pennsylvania

    Date and Place--October 16, 2003 (identified on November 20, 2003); 
Albert Einstein HealthCare Network in Philadelphia, Pennsylvania.
    Nature and Probable Consequences--A patient received a permanent 
brachytherapy implant using iodine-125 (I-125) seeds as treatment for 
prostate carcinoma on October 16, 2003. The authorized user prescribed 
a dose of 145 Gy (14,500 rads) to the prostate gland. The implant was 
performed under ultrasound guidance, and 89 sources were implanted as 
prescribed in the written directive. On November 17, 2003, the patient 
returned for a routine postoperative computerized tomography (CT) scan. 
On November 20, 2003, a review of the scan revealed that many of the 
seeds were not located in the prostate as intended, but were in 
adjacent tissue where they were ineffective during treatment. As a 
result, the prostate gland received an inadequate dose of 18.6 Gy 
(1,860 rads), while the adjacent tissue received a dose of 
approximately 115 Gy (11,500 rads). An NRC medical consultant 
determined that the probable consequences to the patient would be 
comparable to the effects of external beam radiation treatment for 
prostate cancer and would not cause further damage to the patient. The 
patient and the patient's referring physician were notified of the 
event.
    Cause(s)--The licensee determined that this medical event was 
caused by human error, the most likely being the misidentification of 
the prostate gland on the intra-operative ultrasound. Other possible 
causes include shifting of the needle grid in the patient on the 
operating room table or the suction of the seeds into the needle tract 
after the removal of the individual needles from the patient.
Actions Taken To Prevent Recurrence
    Licensee--The licensee's corrective actions for future prostate 
brachytherapy treatments include new requirements that an outside 
radiation oncologist with expertise in prostate brachytherapy will 
monitor authorized users, and an experienced prostate brachytherapist 
will observe authorized users as they perform prostate implant 
procedures. In addition, the licensee implemented revised procedures, 
including performing a pre-operative CT scan; reviewing pre-planned 
ultrasound studies prior to, during, and after the procedure; and 
reviewing postoperative pelvic x-rays within 1 day of the procedure. 
Furthermore, the Radiation Safety Committee will review all forms, 
documents, education, and oversight associated with the permanent 
prostate implant program, and will make recommendations or amendments, 
as necessary, to reflect programmatic changes.
    NRC--The NRC staff conducted a special safety inspection on 
December 5, 2003, and did not identify any violations associated with 
the licensee's actions. The NRC also reviewed the licensee's current 
prostate implant program, and concluded that 12 other I-125 prostate 
implants had been completed without incident.
    This event is closed for the purpose of this report.

04-04 Diagnostic Medical Event at William Beaumont Hospital in Royal 
Oak, Michigan

    Date and Place--June 8, 2004; William Beaumont Hospital; Royal Oak, 
Michigan.
    Nature and Probable Consequences--The licensee reported that a 
patient was prescribed a dose of 0.37 megabecquerels (MBq) [10 
microcuries ([mu]Ci)] of I-131 for a thyroid uptake procedure, but 
instead received 33.86 MBq (915 [mu]Ci) of I-131. The pipette used to 
prepare I-131 therapy dosages earlier in the day was inadvertently used 
to draw the 0.37 MBq (10 [mu]Ci) I-131 uptake dosage. The technician 
properly disposed of the I-131 uptake dosage after identifying the 
error.
    The technician then obtained the ``uptake'' pipette and prepared a 
second dosage from the I-131 bulk uptake solution. However, the 
``uptake'' pipette had inadvertently been switched with the ``therapy'' 
pipette used earlier. This may have occurred because both the thyroid 
``uptake'' pipette and the ``therapy'' pipette had illegible labels. As 
a result, the second dosage contained 0.074 MBq (2 [mu]Ci) of I-131 
remaining from the earlier therapy administrations and the newly drawn 
I-131 prepared for the thyroid uptake. The total activity for the 
second dosage measured 33.86 MBq (915 [mu]Ci). The technician focused 
on drawing the calculated volume required to obtain the prescribed 
activity, rather than the radioactive activity measured in the dose 
calibrator and interpreted the ``0.915 millicuries (mCi)'' displayed on 
the dose calibrator as ``9.15 [mu]Ci.'' The technician electronically 
transferred the dosage measurement from the dose calibrator to a dosage 
label. A second technician administered the dosage to the patient. 
Assuming a 55% uptake, the absorbed dose to the patient's thyroid was 
26.75 Gy (2,675 rads) with an effective dose equivalent of 0.81 Gy (81 
rads). The patient and referring physician were notified of the medical 
event on June 9, 2004. The licensee indicated that the additional 
dosage administered to the patient would not result in any increased 
risk or biological effect to the patient.
    Cause(s)--This event was caused by human error. The nuclear 
medicine technologist who drew the dose misinterpreted the reading on 
the dose calibrator, and the technician who administered the dose did 
not verify the dose before administration.
Actions Taken To Prevent Recurrence
    Licensee--The licensee implemented a requirement to use a new 
pipette each time an I-131 uptake dose is prepared, reprogrammed the 
computer to accept uptake dose activity rather than volume and stopped 
the computer from printing a dose label when the activity is not within 
the established range. The licensee also trained the radiopharmacy 
staff not to override the computer's failsafe mechanisms, and retrained 
the nuclear medicine technologist in the process for dose verification 
prior to administration.
    NRC--The NRC staff conducted a special safety inspection on June 
10, 2004. Then, on September 14, 2004, the NRC issued a Notice of 
Violation for a significant violation involving the administration of a 
dosage of liquid I-131 to a patient for a thyroid uptake study that was 
approximately 90 times

[[Page 22725]]

larger than the 10-[mu]Ci dosage prescribed by the authorized user 
physician.

Agreement State Licensees

    The NRC determined that the following events, which occurred at 
Agreement State licensed facilities during this reporting period, were 
significant enough for reporting as AOs:

AS 04-01 I-125 Brachytherapy Seed Medical Event at Central Arkansas 
Radiation Therapy Institute in Conway, Arkansas

    Date and Place--December 4, 2003; Central Arkansas Radiation 
Therapy Institute; Conway, Arkansas.
    Nature and Probable Consequences--The licensee reported that a 
patient received a radiation dose to an unintended area during an I-125 
prostate-seed implant procedure. The patient was prescribed treatment 
with 122 I-125 seeds, with each seed containing an activity of 13.3 MBq 
(0.36 mCi). During the patient's post-implant CT scan on December 18, 
2003, the licensee discovered that the seeds had been implanted 2 
centimeters (cm) too low and missed treating the upper portion of the 
prostate gland. As a result, 68 cm\3\ of adjacent tissue received the 
prescribed dose of 144 Gy (14,400 rads). The licensee reported that the 
adjacent tissue should not be affected adversely by the dose delivered 
by the seeds. The licensee administered additional treatment to deliver 
the intended dose to the upper 2 cm of the prostate gland. The licensee 
notified the patient and the patient's referring physician of the 
event.
    Cause(s)--This event was attributed to human error in that the 
treatment site was not verified.
Actions Taken To Prevent Recurrence
    Licensee--The licensee wrote a new procedure to implement the use 
of fluoroscopic guidance to ensure the correct placement of seeds.
    State Agency--The State has reviewed and accepted the licensee's 
corrective actions.
    This event is closed for the purpose of this report

AS 04-02 Dose to Fetus at Hillcrest Hospital of Mayfield Heights, Ohio

    Date and Place--November 20, 2003, Hillcrest Hospital; Mayfield 
Heights, Ohio.
    Nature and Probable Consequences--The Ohio Bureau of Radiation 
Protection reported that a 19-year-old female patient was administered 
5.18 gigabequerels (GBq) (140 mCi) of I-131 as prescribed for thyroid 
carcinoma. At the time, the patient was unaware that she was pregnant 
and she completed the required forms indicating that she was not 
pregnant. However, on December 5, 8, and 11, 2003, quantitative tests 
confirmed that the patient was pregnant. The licensee provided the 
results to the patient's endocrinologist, who recommended performing a 
fetal dose calculation. The licensee was notified and its consultant 
informed the endocrinologist that the fetus would have received a whole 
body dose of 0.19 Gy (19.8 rads). The endocrinologist sent the results 
to the Center for Human Genetics at the University Hospital in 
Cleveland, Ohio, where an assessment determined that the pregnancy 
could safely continue.
    Cause(s)--This event was caused by human error. At the time of the 
administration, the patient was unaware of her pregnancy status and 
completed forms indicating that she was not pregnant.
Actions Taken To Prevent Recurrence
    Licensee--The licensee has implemented pregnancy testing for 
patients of child bearing age, who receive radiation therapy.
    State Agency--The Ohio Bureau of Radiation Protection was notified 
of this event on January 16, 2004, and performed a special inspection 
on January 22, 2004. The State found the licensee's corrective actions 
adequate to prevent recurrence.
    This event is closed for the purpose of this report.

AS 04-03 High Dose Rate Afterloader Medical Event at New Orleans Cancer 
Institute at Memorial Medical Center, Louisiana

    Date and Place--March 31, 2004; New Orleans Cancer Institute; New 
Orleans, Louisiana.
    Nature and Probable Consequences--A cancer patient undergoing 
therapeutic radiation treatment for prostate cancer received 18 Gy 
(1,800 rads) to the wrong treatment site. This error occurred using a 
high dose rate (HDR) afterloader device with a radioactive source 
containing 270.7 GBq (7.32 Ci) of Ir-192. The event occurred after the 
dosimetrist made an error while inputting data into the afterloader's 
dosimetry software program. Although the dosimetrist appropriately 
clicked the ``catheter tip'' selection, the dosimetrist did not 
highlight and choose ``catheter tip.'' Therefore, the computer cursor 
stayed on the ``connector end'' selection. This resulted in a 2-cm 
positioning error, which caused the source to stop short of the target 
so that the total prescribed dose was not delivered. The patient was 
informed of the event, and the remaining dose was delivered by external 
beam therapy. According to the Radiation Oncologist, no detrimental 
effects are expected. The patient was self-referred for the therapeutic 
treatment.
    Cause(s)--This event was attributed to operator error.
Actions Taken To Prevent Recurrence
    Actions taken to prevent recurrence include implementing procedures 
to add a visual check and documentation that the treatment plan was 
administered with the source position calculated from the tip end of 
the catheter or needle. This procedure will be added to the pre-
treatment checklist, which is performed and signed by the radiation 
oncologist, physicist, and dosimetrist. The checklist will be performed 
prior to initial treatment and at treatment plan changes, and will be 
part of the patients' permanent records. Also, the licensee contacted 
the device's manufacturer regarding the confusion associated with the 
default orientation in the software program, and requested an 
adjustment to the program. The manufacturer stated that this could not 
be done at this time, but is discussing the issue. The manufacturer 
offered additional training to the licensee's employees, and the 
licensee is sending its employees to the training.
    State Agency--The State accepted the licensee's implementation of 
new procedures and its corrective actions as appropriate.
    This event is closed for the purpose of this report.

AS 04-04 Diagnostic Medical Event at Northeast Alabama Regional Medical 
Center, Alabama

    Date and Place--August 10, 2004; Northeast Alabama Regional Medical 
Center; Montgomery, Alabama.
    Nature and Probable Consequences--A patient received 111 MBq (3,000 
[mu]Ci) of I-131 instead of the prescribed dose of 0.93 MBq (25 
[mu]Ci). The licensee discovered the event on August 12, 2004, when the 
patient returned for the whole body scan 48 hours later. The referring 
physician had requested a diagnostic I-131 scan to assess a thyroid 
nodule, which requires 0.93 MBq (25 [mu]Ci). The technologist 
misunderstood the order by assuming that the referring physician wanted 
a whole body scan to assess thyroid cancer, and administered 111 MBq 
(3,000 [mu]Ci) of I-131 without

[[Page 22726]]

requesting clarification or approval from the authorized users.
    Two authorized users determined that the patient could become 
hypothyroid. Therefore, patient followup assessments included thyroid 
profiles and thyroid uptakes to determine thyroid function. The patient 
and the referring physician were informed of the event.
    Cause(s)--This event was attributed to human error. The 
technologist misunderstood the treatment ordered by the referring 
physician and failed to verify the written directive.
Actions Taken To Prevent Recurrence
    Licensee--The licensee implemented corrective measures to ensure 
that authorized users approve all procedures involving the 
administration of radiopharmaceuticals and re-instructed nuclear 
medicine personnel.
    State Agency--The State conducted an inspection.
    This event is closed for the purpose of this report.

AS 04-05 Occupational Exposure at Palmetto Health and Baptist Hospital 
in Columbia, South Carolina

    Date and Place--March 17, 2004; Palmetto Health and Baptist 
Hospital; Columbia, South Carolina.
    Nature and Probable Consequences--The licensee reported that a 
pharmacist trainee received an extremity exposure resulting in a 
shallow dose equivalent to the hand of 7,420 mSv (742 rem), a deep dose 
equivalent to the hand of 70 mSv (7.02 rem), and a thyroid dose of 0.9 
mSv (0.09 rem). The exposures occurred when a spill took place while 
compounding I-131 from a vial. The pharmacist trainee cleaned up the 
area, decontaminated his skin, and reported the spill to the imaging 
manager the following day. The imaging manager conducted a second 
survey of the area, which showed that no contamination remained from 
the spill. The pharmacist trainee completed a spill report but did not 
reveal his contamination in the report. The pharmacist trainee left for 
vacation and 11 days later, after his return, informed the Radiation 
Safety Officer (RSO) that his forearm had been contaminated during the 
I-131 spill. Immediate actions were taken to determine whether any 
contamination still remained on his arm. Elevated levels were 
discovered on his right forearm and left fingertips. The appropriate 
hospital/nuclear medicine personnel were notified. The pharmacist 
trainee was suspended from any and all duties involving radioactive 
material.
    Cause(s)--This event occurred as a result of human error and 
failure to follow established procedures. An initial crimp failure on 
the vial may also have contributed to the spill.
Actions Taken To Prevent Recurrence
    Licensee--The licensee retrained all staff in spill procedures, 
emphasizing proper notification of supervisors. Additionally, at the 
prompting of the licensee, the vial supplier reevaluated the process of 
ensuring that each crimp is acceptable for shipment, although the 
supplier believed it was more likely an isolated incident.
    State Agency--The State agency conducted inspections and cited the 
licensee for violations of regulations for controlling radiation.

AS 04-06 Gamma Stereotactic Radiosurgery (Gamma Knife) Medical Event at 
Radiosurgical Center of Memphis in Memphis, Tennessee

    Date and Place--January 24, 2003; Radiosurgical Center of Memphis; 
Memphis, Tennessee. This event was not determined to be an AO until the 
preparation of the FY2004 report.
    Nature and Probable Consequences--The licensee reported that a 
patient received 27 Gy (2,700 rads) to a brain metastasis instead of 
the intended 18 Gy (1,800 rads) during gamma knife treatment. The 
physicist did not determine that an error had occurred until the 
treatment was complete. The RSO determined that one of the four brain 
metastases received greater than the prescribed dose. The other three 
brain metastases received the prescribed dose. The tumor that received 
the incorrect dose was at the periphery of the brain next to the skull 
in a non-critical area so that much of the extra dose was delivered to 
the space between the brain and the skull. The cause of the incident 
was that a 14-millimeter (mm) (.55-inch) collimator helmet was used 
instead of the prescribed 8-mm (.31 inch) collimator helmet. The 
personnel setting up the treatment neglected to change the helmet. The 
tumor that received the unintended dose was located at the periphery of 
the brain, adjacent to the skull. Because most of the unintended dose 
was delivered to a non-critical space, between the brain and skull, the 
additional radiation exposure should have no significant effect on the 
patient.
    The referring physician was notified of the event and informed the 
patient's family of the unintended dose.
    Cause(s)--The cause was human error, in that the event resulted 
from use of the wrong collimator helmet.
Actions Taken To Prevent Recurrence
    Licensee--The licensee established a new procedure to require the 
physician, physicist, and nurse to sign off on the treatment time, 
helmet size, and position before each shot. Also, new labels 
identifying the size of the helmet were attached to each of the four 
helmets. These labels can be seen by personnel via the TV monitor 
located at the control panel outside the treatment room. The physician 
will verify the correct size before the control panel button is pushed 
to start the treatment.
    State Agency--The State reviewed and approved the licensee's new 
procedures.

AS 04-07 Strontium-90 Eye Applicator Brachytherapy Medical Event at St. 
Francis Hospital in Memphis, Tennessee

    Date and Place--March 25, 2004; St. Francis Hospital; Memphis, 
Tennessee.
    Nature and Probable Consequences--A 79-year-old patient was 
prescribed radiation treatment for pterygium (an eye abnormality). The 
patient was to receive 20 Gy (2,000 rads), but instead received 70 Gy 
(7,059 rads). The prescribed dose was to be administered via a Sr-90 
radioactive source with an activity of 3.7 GBq (100 mCi) for a duration 
of 42.5 seconds. However, the manual timer was incapable of being set 
for fractions of a second and interpreted the entry to be 4 minutes and 
25 seconds. During the treatment, the physician questioned the 
treatment time and terminated the treatment after 2 minutes and 30 
seconds. The Radiation Oncologist concluded that the maximum possible 
dose delivered to the sclera was well below the sclera tolerance dose 
and that the optic nerve and retina did not receive any meaningful 
dose. The patient and the referring physician were notified of the 
event.
    Cause(s)--The wrong treatment time was programmed for the patient's 
eye treatment.
Actions Taken To Prevent Recurrence
    Licensee--The licensee updated its procedures, which require use of 
an additional person to operate a second timer during brachytherapy eye 
treatment.
    State Agency--The Tennessee Department of Radiological Health 
conducted an onsite inspection on March 29, 2004. The State 
investigated, reviewed, and approved the licensee's new procedures.
    This event is considered closed for the purpose of this report.

AS 04-08 Therapeutic Medical Event at Southern Regional Medical Center 
in Riverdale, Georgia

    Date and Place--July 1, 2004; Southern Regional Medical Center; 
Riverdale, Georgia.
    Nature and Probable Consequences--The licensee informed the Georgia 
Department of Natural Resources (GDNR) that a patient received 3.7 GBq 
(100 mCi) of I-131 instead of the prescribed dose of 0.64 GBq (17.3 
mCi). Three patients were scheduled for I-131 treatments on the same 
day. An inpatient was scheduled to receive 3.7 GBq (100 mCi), and two 
outpatients were scheduled to receive less than 1.2 GBq (33 mCi). One 
of the outpatients was mistakenly injected with the 3.7 GBq (100 mCi) 
dose intended for the inpatient and was also allowed to leave the 
facility without receiving proper instructions. The licensee did not 
discover the error until after the patient had left the facility with 
her children. The authorized user who signed the written directive was 
at the facility when the dose was administered. The temporary RSO was 
at South Fulton Hospital, but was notified of the event. The patient 
and referring physician were immediately notified of the event by the 
licensee. The GDNR received a report from the licensee's medical 
physicist consultant estimating the dose to the patient's children was 
0.5 mSv (0.05 rem), with a maximum possible dose of 1.0 mSv (0.1 rem). 
The radiation should not have any effects on the patient's children or 
other individuals. The medical significance to the patient is the 
possibility of developing hypothyroidism which would require thyroid 
medication.
    Cause(s)--This event was attributed to human error. The wrong 
patient was administered a therapeutic dose of I-131 that was 
prescribed for someone else.
Actions Taken To Prevent Recurrence
    Licensee--The licensee discussed the incident with all technicians 
who prepare and administer I-131, revised nuclear medicine protocols 
pertaining to the therapeutic use of I-131 and patient instructions, 
and revised procedures to incorporate better practices to prevent this 
type of error from recurring.
    State Agency--The State agency reviewed and approved the corrective 
actions that the licensee implemented to prevent recurrence.
    This event is considered closed for the purpose of this report.

AS 04-09 Intravascular Brachytherapy Medical Event at Ireland Cancer 
Center in Middleburg Heights, Ohio.

    Date and Place--December 22, 2003; Ireland Cancer Center; 
Middleburg Heights, Ohio.
    Nature and Probable Consequences--The licensee reported that a 
patient received a radiation dose to an unintended site 3 cm proximal 
to the prescribed treatment site during an intravascular brachytherapy 
(IVB) treatment procedure. The dose delivered to the unintended site 
was approximately 18.40 Gy (1,840 rads). The event involved an IVB 
device that used a 3.5-mm catheter and a source train that contained 
Sr-90 with an activity of 2.0 GBq (53.8 mCi). The source train traveled 
to a location approximately 3 cm proximal to the intended treatment 
site. It was determined that there was a kink in the delivery catheter, 
which kept the source train from traveling to the correct site. The 
kink was not substantial enough to affect the flow of sterile water 
used to send and retrieve the source train. The kink was discovered the 
following day during medical physics quality checks. The referring 
physician and patient were notified of the event. According to the 
licensee, no adverse effects are expected.
    Cause(s)--The cause of the event was determined to be a kink in the 
delivery catheter, which kept the source train from traveling to the 
correct site.
Actions Taken To Prevent Recurrence
    Licensee--Corrective actions incorporated by the licensee included 
additional films taken during procedures to verify the placement of the 
catheter. When there is any doubt of the placement of the catheter, the 
treatment will be aborted. The treatment team will then evaluate 
whether to attempt treatment with a different catheter.
    State Agency--The Ohio Department of Health conducted an 
investigation, reviewed the licensee's corrective actions, and found 
them adequate to prevent recurrence.
    This event is considered closed for the purpose of this report.

AS 04-10 Intravascular Brachytherapy Medical Event at Swedish Medical 
Center in Seattle, Washington

    Date and Place--November 18, 2003; Swedish Medical Center; Seattle, 
Washington.
    Nature and Probable Consequences--A patient undergoing an 
intravascular brachytherapy (IVB) treatment for coronary restenosis 
received 13.78 Gy (1,378 rads) to an unintended site (healthy tissue). 
The licensee reported that the source train was partially inserted into 
a small artery, and the routing did not follow a direct path. When the 
difficulty occurred, the source train had been partially inserted 65 mm 
proximal to the intended site. The source train contained a total 
activity of 2.91 GBq (78.56 mCi). A 143-second exposure time elapsed 
before the cardiologist withdrew the source train, even though the 
licensee's procedure requires sources to be immediately withdrawn once 
a problem occurs. The delay occurred as the cardiologist first worked 
to fully insert the source train and then discussed correcting the 
problem with the oncologist. The catheter was examined, and there were 
no kinks or bends. It was determined that there were no failures of the 
IVB device. It was suspected that the pressure from the artery and the 
tortuous route to the site caused a contraction of a portion of the 
catheter and resulted in the seeds becoming stuck at a particular 
location. The cardiologist was suspended from licensed activities until 
the details of the event were fully understood. According to the 
licensee, no adverse health effects are expected. The patient and the 
patient's referring physician were notified of the event.
    Cause or Causes--It is suspected that the pressure from the small 
artery and the tortuous route to the site caused a contraction of a 
portion of the source train and resulted in the seeds becoming stuck at 
a particular location.
Actions Taken To Prevent Recurrence
    Licensee--Corrective actions included reemphasizing the importance 
of adhering to established procedures and protocols before 
administering radiopharmaceuticals, and ensuring that all staff 
completed refresher training.
    State Agency--The State reviewed and approved the corrective 
actions taken by the licensee and will follow-up at the next 
inspection.
    This event is closed for the purpose of this report.

    AS 04-11 Diagnostic Medical Event at Swedish Medical Center in 
Seattle, Washington
    Date and Place--September, 24, 2004; Swedish Medical Center; 
Seattle, Washington.
    Nature and Probable Consequences--The licensee reported that a 
patient received 190.9 MBq (5.16 mCi) of I-131, instead of the 
prescribed 74 MBq (2 mCi) for a post thyroid treatment follow-up scan. 
The prescribing physician

[[Page 22728]]

realized that the error occurred on September 27, 2004, when the 
patient underwent the scan. A viable follow-up scan was performed even 
though the error occurred. The referring physician notified the patient 
of the error on September 27, 2004. The nuclear medicine physician 
indicated there would be no negative health effects from this 
administration.
    Cause or Causes--The licensee stated that human error led to 
procedural checks not being performed prior to the administration.
Actions Taken To Prevent Recurrence
    Licensee--Corrective actions included re-emphasis on the importance 
of adhering to established procedures and protocols prior to the 
administration of radiopharmaceuticals and the completion of staff 
refresher training.
    State Agency--The State reviewed and approved the corrective 
actions taken by the licensee and will follow-up at the next 
inspection.
    This event is considered closed for the purpose of this report.

AS 04-12 Therapeutic Medical Event at University of California at Los 
Angeles Harbor Medical Center in Torrance, California

    Date and Place--June 7, 2002; Los Angeles County Harbor University 
of California at Los Angeles (UCLA) Medical Center; Torrance, 
California. This event was not identified as an AO until the 
preparation of the FY 2004 report.
    Nature and Probable Consequences--A patient receiving treatment for 
thyroid ablation was administered a dose of 4.74 GBq (128 mCi) of I-131 
instead of the prescribed dose of 1.18 GBq (32 mCi) of I-131.
    On June 7, 2002, five patients were scheduled to be treated with I-
131. Five vials containing I-131 arrived from the radiopharmacy and 
were properly labeled with the patients' names. The nuclear medicine 
technologist incorrectly thought that the name on the 4.74 GBq (128mCi) 
vial did not match any of the patient's names scheduled for treatment 
that day. Assuming that this vial was incorrectly labeled, the 4.74 GBq 
(128 mCi) dosage was administered to the patient for whom the 
technologist thought the dose was intended. However, the technologist 
failed to verify whether any of the remaining four dosages were labeled 
for that patient. In fact, a vial was correctly labeled as prepared for 
that patient.
    The authorized user was present during the administration to 
supervise the administration of the radiopharmaceutical, and to verify 
that the correct radiopharmaceutical and dosage were administered. The 
authorized user did not perform an independent verification, but 
instead assumed that the nuclear medicine technologist had verified 
that the dosage was correct. The error was discovered about 5 hours 
later, when the patient scheduled to receive the 4.74 GBq (128 mCi) 
dosage arrived at the medical center for treatment. The patient and the 
referring physician were notified. The authorized user went to the home 
of the patient who received the inadvertent administration and verified 
that appropriate radiation safety precautions were in place. The 
patient's treatment plans were modified to accommodate the larger 
dosage. The authorized user stated that the dosage was intended to 
ablate the thyroid and render the patient hypothyroid, and that was 
accomplished with the larger dose. He further stated the patient is 
doing well, with no complications.
    Cause(s)--This medical event was caused by human error which 
resulted in the licensee's failure to follow proper policies and 
procedures and verify the prescribed dosage for a specific patient.
Actions Taken To Prevent Recurrence
    Licensee--The licensee re-instructed all nuclear medicine personnel 
on the importance of following the division's policies and procedures 
and the use of a third party to check the prescription dose and patient 
identification before administration. Additionally, the RSO will review 
all I-131 therapy documents and administrations.
    State Agency--The State cited the licensee for failure to provide 
written notification to the referring physician and the patient within 
15 days after the occurrence of the medical event. The State has 
reviewed and approved the licensee's corrective actions.

AS 04-13 Diagnostic Medical Event at University Hospital in Cincinnati, 
Ohio

    Date and Place--March 10, 2004; University Hospital; Cincinnati, 
Ohio.
    Nature and Probable Consequences--The licensee reported that a 
patient was given 74 MBq (2,000-Ci) of I-131 for a thyroid cancer work-
up instead of the prescribed dose of 7.4 MBq (200-Ci) of I-123 for a 
thyroid uptake scan. The patient scheduled to receive the I-123 dose 
responded affirmatively to being the patient that was to receive the I-
131 dose. The technologist did not follow procedures regarding proper 
identification of the patient, which requires two separate methods for 
verifying patient identification. A follow-up scan revealed the patient 
does have hypothyroidism, and as a result, the 74 MBq (2,000-Ci) of I-
131 would have been prescribed based on the scan results. The referring 
physician and patient were notified. No adverse health effects are 
expected.
    Cause or Causes--The technologist failed to follow established 
procedures.
Actions Taken to Prevent Recurrence
    Licensee--The licensee disciplined the technologist in accordance 
with hospital policy and reiterated to all technologists the need to 
thoroughly check patient identification using two approved methods. 
Additionally, the Radiation Safety Committee modified the Quality 
Management Program to require a photo as one method of verifying 
patient identification.
    State Agency--The Ohio Department of Health conducted an 
investigation of the event on May 11, 2004, and reviewed the licensee's 
corrective actions. The State found the licensee's corrective actions 
adequate to prevent a recurrence of the event.
    This event is closed for the purpose of this report.

    Dated at Rockville, Maryland this 18th day of April 2005.

    For the Nuclear Regulatory Commission
Annette L. Vietti-Cook,
Secretary of the Commission.
