Kan. Admin. Regs. § 28-35-349 - Design, performance, and certification criteria for sealed sources used in downhole operations
(a) Each sealed
source that is used in downhole operations and manufactured after May 1, 1991
shall be certified by the manufacturer or other testing organization to meet
the following minimum criteria.
(1) Each
source shall be doubly encapsulated.
(2) Each source shall contain radioactive
material with a chemical and physical form that is as insoluble and
nondispersive as practical.
(3)
Each source's prototype shall have been tested and found to maintain its
integrity after each of the following tests:
(A) Temperature. The test source shall be
held at -40° C for 20 minutes and at 600° C for one hour. Then the test source
be subjected to a thermal shock test with a temperature drop from 600° C to 20°
C within 15 seconds.
(B) Impact
test. A five-kg steel hammer with a diameter of 2.5 cm shall be dropped from a
height of one meter onto the test source.
(C) Vibration test. The test source shall be
subject to a vibration from 25 Hz to 500 Hz at five g (gravitational
acceleration) amplitude for 30 minutes.
(D) Puncture test. A one-gram hammer with a
pin having a diameter of 0.3 cm shall be dropped from a height of one meter
onto the test source.
(E) Pressure
test. The test source shall be subjected to an external pressure of 24,600
pounds per square inch absolute (1.695 x 107 pascal).
(b) No sealed source acquired
after May 1, 1992 shall be put into use in the absence of a certificate from a
transferor certifying that the sealed source meets the requirements of
subsection (a), until the required determinations and testing have been
performed.
(c) Each sealed source
that is used in downhole operations after May 1, 1992 shall be certified by the
manufacturer or other testing organization as meeting the sealed source
performance requirements for oil well-logging contained in "sealed radioactive
sources-classification," ANSI/HPS N43.6-1997, including the annexes, approved
by the American national standards institute, inc. in November 1997, published
by the health physics society, and hereby adopted by reference.
(d) Certification documents shall be
maintained for inspection by the department for a period of two years after
source disposal. If the source is abandoned downhole, the certification
documents shall be maintained until the department authorizes disposition of
these documents.
(e) The
requirements in subsections (a), (b), (c), and (d) shall not apply to any
sealed sources that contain licensed material in gaseous form.
(f) The requirements in subsections (a), (b),
(c), and (d) shall not apply to any energy compensation sources (ECS). Each ECS
shall be registered with the department, NRC, or an agreement state.
