64E-5.1107. Design, Performance and Certification Criteria for Sealed Sources Used in Downhole Operations

(1) A licensee can use a sealed source in well logging applications if:

(a) The sealed source is doubly encapsulated;

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

(c) The sealed source meets requirements specified in subsection (2), (3), or (4), below.

(2) A licensee can use a sealed source manufactured on or before July 14, 1989, in well logging applications if it meets the requirements of USASI N5.10 - 1968, “Classification of Sealed Radioactive Sources”, which is herein incorporated by reference and available from the Department, or the requirements specified in subsections (3) and (4), below.

(3) A licensee can use a sealed source manufactured after July 14, 1989, in well logging applications if it meets the oil-well logging requirements specified in ANSI/HPS N43.6 1997, “Sealed Radioactive Sources Classification,” which is herein incorporated by reference and available from the Department.

(4) A licensee can use a sealed source manufactured after July 14, 1989, in well logging applications if:

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

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

(b) Impact test. A 5 kg steel hammer 2.5 cm in diameter is dropped from a height of 1 m onto the test source.

(c) Vibration test. The test source is subjected to a vibration from 25 Hz to 500 Hz at 5 g amplitude for 30 minutes.

(d) Puncture test. A 1 gram hammer and 0.3 cm diameter pin is dropped from a height of 1 m onto the test source.

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

(5) The requirements of subsections (1) through (4), above, do not apply to sealed sources that contain licensed material in gaseous form.

(6) The requirements of subsections (1) through (4), above, do not apply to ECSs. ECSs shall be registered with the Department as specified in subsection 64E-5.210(14), F.A.C., the U.S. Nuclear Regulatory Commission, an Agreement State, or a Licensing State.
