Universal Citation: 180 NE Admin Rules and Regs ch 14 ยง 010

Current through September 17, 2024

010.01 SEALED SOURCE USE. A licensee may use a sealed source for use in well logging application if the sealed source:

(A) Is doubly encapsulated;

(B) Contains radioactive material whose chemical and physical forms are as insoluble and nondispersible as practical; and

(C) Meets the requirements in 180 NAC 14-010.02, 010.03, or 010.04.

010.02 SEALED SOURCES MANUFACTURED ON OR BEFORE JULY 14, 1989. For a sealed source manufactured on or before July 14, 1989, a licensee may use the sealed source for use in well logging applications if it meets the requirements of USASI N5.10-1968, "Classification of Sealed Radioactive Sources", or the requirements in 180 NAC 14-010.03 and 010.04.

010.03 SEALED SOURCES MANUFACTURED AFTER JULY 14, 1989. For a sealed source manufactured after July 14, 1989, a licensee may use the sealed source for use in well logging applications if it meets the oil-well logging requirements of ANSI/HPS N43.6-1997, "Sealed Radioactive Sources - Classification."

010.04 ADDITIONAL REQUIREMENTS FOR SEALED SOURCES MANUFACTURED AFTER JULY 14, 1989. For a sealed source manufactured after July 14, 1989, a licensee may use the sealed source for use in well logging applications, if:

(A) The sealed source's prototype has been tested and found to maintain its integrity after each of the following tests:
(i) Temperature. The test source must be held at -40°Celsius (-40°Fahrenheit) for 20 minutes, 600°Celsius (1112°Fahrenheit) for 1 hour, and then be subject to a thermal shock test with a temperature drop from 600°Celsius (1112°Fahrenheit) to 20°Celsius (68°Fahrenheit) within 15 seconds

(ii) Impact test. A 5 kilogram steel hammer, 2.5 centimeters in diameter, must be dropped from a height of 1 meter onto the test source.

(iii) Vibration test. The test source must be subject to a vibration from 25 hertz to 500 hertz at 5 G amplitude for 30 minutes.

(iv) Puncture test. A 1 gram hammer and pin, 0+.3 centimeters pin diameter, must be dropped from a height of 1 meter onto the test source.

(v) Pressure test. The test source must be subjected to an external pressure of 1. 695E+7 pascals (24,600 pounds per square inch absolute).

010.05 EXEMPTIONS. The requirements in 180 NAC 14-010.01 through 14-010.04 do not apply to sealed sources that contain radioactive material in gaseous form.

010.06 ENERGY COMPENSATION SOURCE EXEMPTIONS. The requirements in 180 NAC 14-010.01, 010.02, 010.03 and 010.04 do not apply to ECS. ECSs must be registered with the NRC under 10 CFR 32.210 or with an Agreement State.
