6 Colo. Code Regs. § 1007-1-19.7

Current through Register Vol. 47, No. 11, June 10, 2024
Section 6 CCR 1007-1-19.7 - Requirements and performance criteria for sealed sources

Sealed sources shall:

19.7.1 Have a certificate of registration issued by the NRC or an Agreement State, or shall have been evaluated in accordance with 10 CFR Part 32.210 or the equivalent state regulation;
19.7.2 Be doubly encapsulated;
19.7.3 Use radioactive material that is as nondispersible as practical and that is as insoluble as practical if the source is used in a wet-source-storage or wet-source-change irradiator;
19.7.4 Be encapsulated in a material resistant to general corrosion and to localized corrosion, such as 316L stainless steel or other material with equivalent resistance if the sources are used in irradiator pools; and
19.7.5 Have been leak tested in prototype testing and found leak-free after each of the tests described in 19.7.5.1 through 19.7.5.6.
19.7.5.1 Temperature Test.

The test source must be held at-40°C for 20 minutes, 600°C for 1 hour, and then be subjected to a thermal shock test with a temperature drop from 600°C to 20°C within 15 seconds.

19.7.5.2 Pressure Test.

The test source must be twice subjected for at least 5 minutes to an external pressure (absolute) of 2 megapascal (2 million newton) per square meter.

19.7.5.3 Impact Test.

A 2-kilogram steel weight, 2.5 centimeters in diameter, must be dropped from a height of 1 meter onto the test source.

19.7.5.4 Vibration Test.

The test source must be subjected 3 times for 10 minutes each to vibrations sweeping from 25 hertz to 500 hertz with a peak amplitude of 5 times the acceleration of gravity. In addition, each test source must be vibrated for 30 minutes at each resonant frequency found.

19.7.5.5 Puncture Test.

A 50-gram weight and pin, 0.3-centimeter pin diameter, must be dropped from a height of 1 meter onto the test source.

19.7.5.6 Bend Test.

If the length of the source is more than 15 times larger than the minimum cross-sectional dimension, the test source must be subjected to a force of 2000 newton at its center equidistant from two support cylinders, the distance between which is 10 times the minimum cross-sectional dimension of the source.
