Current through Register Vol. 35, No. 21, November 5, 2024

Section 20.3.12.21 - DESIGN AND PERFORMANCE CRITERIA FOR SEALED SOURCES

A. A licensee may use a sealed source for use in well logging applications if:

(1) the sealed source is doubly encapsulated;

(2) the sealed source contains licensed material whose chemical and physical forms are as insoluble and nondispersible as practical; and

(3) meets the requirements of Subsections B, C and D of this section.

B. 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 Subsections C and D of this section.

C. 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.

D. For a sealed source manufactured after July 14, 1989, a licensee may use the sealed source, for use in well logging applications, if the sealed source's prototype has been tested and found to maintain its integrity after each of the tests in Paragraphs (1) through (5) of this subsection.

(1) Temperature. The test source shall be held at -40 degrees celsius for 20 minutes, 600 degrees celsius for 1 hour, and then be subject to a thermal shock test with a temperature drop from 600 degrees celsius to 20 degrees celsius within 15 seconds.

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

(3) Vibration test. The test source shall be subject to a vibration from 25 hertz to 500 hertz at 5 g (g meaning the acceleration due to gravity) amplitude for 30 minutes.

(4) Puncture test. A 1 gram hammer and pin, 0.3 centimeter pin diameter, shall be dropped from a height of 1 meter onto the test source.

(5) Pressure test. The test source shall be subject to an external pressure of 1.695x107 pascals (24,600 pounds per square inch absolute).

E. The requirements in Subsections A, B, C and D of this section do not apply to sealed sources that contain licensed material in gaseous form.

F. The requirements in Subsections A, B, C and D of this section do not apply to energy compensation sources (ECS). ECSs shall be registered with the sealed source and device registry (see definition in 20.3.1.7 NMAC) upon an approval by the NRC under 10 CFR 32.210 or an agreement state equivalent regulations.
