Section 61-63.VIII.RHA 8.13 - Criteria for Sealed Source Design and Integrity

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

8.13.1.1 The sealed source is doubly encapsulated;

8.13.1.2 The sealed source contains radioactive material whose chemical and physical forms are as insoluble and nondispersible as practical; and

8.13.1.3 The sealed source meets the requirements of RHA 8.13.2, 8.13.3 or 8.13.4.

8.13.2 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 RHA 8.13.3 or 8.13.4 of this section.

8.13.3 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."

8.13.4 For a sealed source manufactured after July 14, 1989, a licensee may use the sealed source, for use in well logging applications, if--

8.13.4.1 The sealed source's prototype has been tested and found to maintain its integrity after each of the following tests:

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

8.13.4.1.2 Impact Test. A 5kg steel hammer, 2.5cm in diameter, must be dropped from a height of 1m onto the test source.

8.13.4.1.3 Vibration Test. The test source must be subject to a vibration from 25Hz to 500Hz at 5g amplitude for 30 minutes.

8.13.4.1.4 Puncture Test. A 1 gram hammer and pin, 0.3cm pin diameter, must be dropped from a height of 1m onto the test source.

8.13.4.1.5 Pressure Test. The test source must be subjected to an external pressure of 24,600 pounds per square inch absolute (1.695 x 10⁷ pascals).

8.13.5 The requirements in RHA 8.13.1, 8.13.2, 8.13.3 and 8.13.4 do not apply to sealed sources that contain radioactive material in gaseous form.

8.13.6 The requirements in RHA 8.13.1, 8.13.2, 8.13.3 and 8.13.4 of this section do not apply to energy compensation sources (ECS). ECSs must be registered with the Department under RHA 2.29 or with the NRC under Sec.32.210.

8.13.7 Energy compensation source. The licensee may use an energy compensation source (ECS) which is contained within a logging tool, or other tool components, only if the ECS contains quantities of licensed material not exceeding 100 microcuries (3.7 MBq).

(a) For well logging applications with a surface casing for protecting fresh water aquifers, use of the ECS is only subject to the requirements of RHA 8.10, 8.11, and 8.12.

(b) For well logging applications without a surface casing for protecting fresh water aquifers, use of the ECS is only subject to the requirements of RHA 8.5, 8.10, 8.11, 8.12, 8.18, and 8.27.

8.13.8 Tritium neutron generator target source.

(a) Use of a tritium neutron generator target source, containing quantities not exceeding 30 curies (1,110 MBq) and in a well with a surface casing to protect fresh water aquifers, is subject to the requirements of this part except RHA 8.5, 8.13, and 8.27.

(b) Use of a tritium neutron generator target source, containing quantities exceeding 30 curies (1,110 MBq) or in a well without a surface casing to protect fresh water aquifers, is subject to the requirements of this part except RHA 8.13.
