L. 93– 438) defines an abnormal occurrence (AO) as an unscheduled incident or event that 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. 104–68) requires that AOs be reported to Congress annually. During fiscal year 2010, fifteen events that occurred at facilities licensed or otherwise regulated by the NRC and/or Agreement States were determined to be AOs. This report describes eight events at NRC-licensed facilities. The first event involved radiation exposure to an embryo/fetus. The other seven events occurred at NRC-licensed or regulated medical institutions and are medical events as defined in Title 10, Part 35, of the Code of Federal Regulations (10 CFR part 35). The report also describes seven events at Agreement State-licensed facilities. Agreement States are the 37 States that currently 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. The first two Agreement State-licensee events involved radiation exposure to an embryo/fetus. The other five Agreement State-licensee events were medical events as defined in 10 CFR part 35 and occurred at medical institutions. 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 actions taken to prevent recurrence. Each event is also being described in NUREG–0090, Vol. 33, ‘‘Report to Congress on Abnormal Occurrences: Fiscal Year 2010.’’ This report is available electronically at the NRC Web site at http://www.nrc.gov/ reading-rm/doc-collections/nuregs/staff/ . VerDate Mar<15>2010 17:48 Jun 28, 2011 Jkt 223001 Three major categories of events are reported in this document—I. For All Licensees, II. For Commercial Nuclear Power Plant Licensees, and III. Events at Facilities Other Than Nuclear Power Plants and All Transportation Events. The full report, which is available on the NRC Web site, provides the specific criteria for determining when an event is an AO. It also discusses ‘‘Other Events of Interest,’’ which does not meet the AO criteria but has been determined by the Commission to be included in the report. The event identification number begins with ‘‘AS’’ for Agreement State AO events and ‘‘NRC’’ for NRC AO events. Management Agency that the administration had occurred 3 years earlier. The Illinois Emergency Management Agency calculated an estimated dose to the fetus of 860 mSv (86 rem) and the fetal thyroid of over 1,000,000 mSv (100,000 rem). A fullterm child was subsequently born in August 2007 without a thyroid. The child was immediately placed on replacement hormone therapy and continues such treatment. Cause(s)—The cause of the event was found to be a combination of miscommunication and failure of the licensee to conduct an independent confirmatory pregnancy test. I. For All Licensees Actions Taken To Prevent Recurrence Licensee—The licensee has subsequently made procedural changes to the interview process for screening patients for iodine-131 treatment. This policy includes a confirmatory negative pregnancy test. In addition, the licensee identified the significant delay in reporting the event to the Illinois Emergency Management Agency as not knowing the reporting requirement for this type of event. State—The Illinois Emergency Management Agency conducted an investigation of the event and issued a Notice of Violation (NOV) for the licensee’s failure to report the event. The Illinois Emergency Management Agency is considering rulemaking to require the performance of testing to determine pregnancy prior to administration of iodine-131. A. Human Exposure to Radiation From Licensed Material During this reporting period, one event at an NRC-licensed or regulated facility and two events at Agreement State-licensed facilities were significant enough to be reported as AOs. Although these events occurred at medical facilities, they involved unintended exposures to individuals who were not patients. Therefore, these events belong under the criteria I.A, ‘‘For All Licensees’’ category as opposed to the criteria III.C, ‘‘For Medical Licensees’’ category. AS10–01 Human Exposure to Radiation at Mohamed Megahy MD, Ltd in Maryville, Illinois Date and Place—May 1, 2007 (reported on June 17, 2010), Maryville, Illinois. Nature and Probable Consequences— Mohamed Megahy MD, Ltd (the licensee) indicated that on May 1, 2007, a patient was given 3,807 MBq (102.9 mCi) of iodine-131 as a treatment for the recurrence of thyroid cancer. On June 11, 2007, the licensee was contacted by the patient’s obstetrician/gynecologist (OB/GYN) who advised them that the patient was 25–27 weeks (6 months) pregnant at the time of the iodine-131 administration. At the time of administration, the patient indicated to the licensee that she was not pregnant, and the licensee did not perform an independent test. In June 2010, the Illinois Emergency Management Agency was contacted by the licensee and requested to make a dose estimate to a fetus as a result of administration of iodine-131 to a patient who was later found to be pregnant. When the Illinois Emergency Management Agency requested additional information to determine the appropriate parameters of the event, the licensee advised the Illinois Emergency PO 00000 Frm 00107 Fmt 4703 Sfmt 4703 AS10–02 Human Exposure to Radiation at Mercy Medical Center in Durango, Colorado Date and Place—March 16, 2010, Durango, Colorado. Nature and Probable Consequences— Mercy Medical Center (the licensee) reported that a therapeutic dose of 1,110 MBq (30 mCi) of iodine-131 for hyperthyroidism resulted in a dose to an embryo of 80 mGy (8 rem) whole body. Prior to the treatment, the patient informed the licensee’s staff that she was not pregnant and the licensee’s staff administered a pregnancy test as a routine precaution. The pregnancy test yielded a negative result. Based on the negative pregnancy test results and the patient’s interview responses, the licensee administered iodine-131 to the patient. On April 26, 2010, the patient performed a home pregnancy test that resulted in a positive test result. The patient’s pregnancy was confirmed with a positive blood serum pregnancy test on April 27, 2010. The patient’s OB/ GYN estimated that conception E:\FR\FM\29JNN1.SGM 29JNN1

SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
issuing a revision to an existing guide in the agency's ``Regulatory 
Guide'' series. This series was developed to describe and make 
available to the public information such as methods that are acceptable 
to the NRC staff for implementing specific parts of the agency's 
regulations, techniques that the staff uses in evaluating specific 
problems or postulated accidents, and data that the staff needs in its 
review of applications for permits and licenses.
    Revision 2 of Regulatory Guide (RG) 1.107 entitled, ``Qualification 
for Cement Grouting for Prestressing Tendons in Containment 
Structures,'' was issued with a temporary identification as Draft 
Regulatory Guide, DG-1196.
    This guide describes a method that the staff of the U.S. Nuclear 
Regulatory Commission considers acceptable for the use of Portland 
cement grout as the corrosion inhibitor for prestressing tendons in 
prestressed concrete containment structures. This guide also provides 
quality standards for using Portland Cement grout to protect 
prestressing steel from corrosion.
    The prestressing tendon system of a prestressed concrete 
containment structure is a principal strength element of the structure. 
The ability of the containment structure to withstand the events 
postulated to occur during the life of the structure depends on the 
functional reliability of the structure's principal strength elements. 
Thus, any significant deterioration of the prestressing elements caused 
by corrosion may present a potential risk to public safety. It is 
important that any system for inhibiting the corrosion of prestressing 
elements must possess a high degree of reliability in performing its 
intended function.

II. Further Information

    In October 2010, DG-1196 was published with a public comment period 
of 60 days from the issuance of the guide. The public comment period 
closed on December 11, 2010. Electronic copies of Regulatory Guide 
1.107, Revision 2 are available through the NRC's public Web site under 
``Regulatory Guides'' at http://www.nrc.gov/reading-rm/doc-collections/
