Oil Well Logging Source DESCRIPTION:

Americium oxide powder and beryllium powder are mixed in an inner l

stainless steel capsule sealed by an end plug and a continuous inert gas weld and having a minimum wall thickness of 0.045 inch l

(1.14 mm).

The inner capsule is sealed in an outer stainless steel capsule having a minimum wall thickness of 0.025 inch (0.64 mm) by use of an end plug and a continuous inert gas weld.

The bottom of the source (plug-end) includes a 1/4-20 thread tap l

0.200 inch ( 5. 0 8 mm) deep in the 0.250 inch (6.4 mm) thick plug.

l Overall length of the capsule is 2 inches (50.8 mm) and overall diameter is 0.75 inch (19.05 mm).

LABELING:

The model and serial number of each source is stamped in the bottom of the source.

l DIAGRAM:

(

l CONDITIONS OF NORMAL USE:

1 The source is designed for use in well logging applications and has been issued a generic exception to be used in such l

applications (reference November 1, 1991, letter from John Glenn, NRC).

i l

PROTOTYPE TESTING:

This source had been tested and classified under the ANSI N5.10-1968 standard as E66535.

This included temperature, external pressure, impact, vibration, puncture, and weld penetration tests.

Oil Well Logging Source EXTERNAL RADIATION LEVELS:

The neutron yield of the source is 2.2 x 10' neutrons per second per curie.

The gamma f actor is 10.1 mR m'/hr-Ci.

OUALITY ASSURANCE AND CONTROL:

The integrity of each finished source was checked by the " Helium i

Pressurization Bubble test".

The source must have had less than 0.005 microcurie (185 Bq) removable contamination.

LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:

  • The source shall only be used by specific licensees of NRC or Agreement States.

l

  • The source shall be leak tested at intervals not to exceed 6 months using techniques capable of detecting 0.005 microcurie (185 Bq) of removable contamination.
  • Handling, storage, use, transfer, and disposal: To be determined by the licensing authority.
  • This registration sheet and the information contained within I

the references shall not be changed without the written consent of the NRC.

SAFETY ANALYSIS

SUMMARY

The PL-104 Oil Well Logging source was originally approved for licensing purposes by the Atomic Energy Commission (AEC) on l

December 3, 1971.

This source is no longer manufactured and distributed by Parkwell Laboratories.

The company is out of business.

There is insufficient information on file for this source to have performed a complete safety evaluation.

Therefore, this registration certificate has been transferred to inactive status without further review based on the original review and approval issued by the AEC.

Insocction on January 21. 1993 (Recort No. 030-05868/93001(DRSSH Areas insoected: This was a special closcout inspection which included a review of the licensee's former activities associated with the decontaminatio ^ and remediation of their formerly used office, manufacturing, and laboratory c areas located at 429 North High Street, Croton, Ohio. This inspection was in response to an NRC project,in which an evaluation of approximately 17,000 retired licenses was conducted by an NRC contractor, Oak Ridge National Laboratories (ORNL). On the basis of the information in the retired license files, sites having a potential for significant residual contamination in their former facilities were to be investigated further. Due to the lack of documentation in the General Nuclear, Inc. and Parkwell Laboratories, Inc. retired license file, the NRC contractor concluded that the former facilities f,' used by these companies during the period of 1965-1980 could have significant amounts of residual contamination. Results: The NRC inspector did not identify any radiation levels above natural background within the facilities or surrounding environment. Based %pg/--5 0 / + .I.. .__ 9GO62pe&49 930611 E',i(, c'.'

License No. 34-11105-01.was issued on June 24, %/', 1965, and was terminated on february 3,.1970.4 In two letters to the pE Commission dated February 24, 1967, and March 1, 1967, the licensee y' informed the Commission that all assets and materials possessed by Parkwell Laboratories have been assigned to General Nuclear, Inc. (see 4:.% Attachment A). In another letter to the Commission dated Occomber 10, E '. 1969, the licensee stated.that all radioactive materials were @/ transferred to their Texas License No. 4-734 and the only material that / remained was contaminated hoods and glove boxes which was possessed W., under License No. 34-13517-01 (see Attachment B). Subsequent telephone 'I hg?.i conversations were made between NRC Region'111~ staff and Mr. Charles b Wells (now deceased) in the early 1980's prior to the termination of M@J t.icense No. 34-13517-01, in which Mr. Wells indicated that these contaminated items were buried in' two burials in accordance with ff 10 CFR 20.304 sometime in early 1980. These burials consisted of less g than 20.0 microcuries of americium-241 as contaminated equipment, metal, W and concrete (see Attachment C). During this inspection, Mrs. Nancy G[, Wells (wife of the deceased), informed the inspector that she was not aware of any burials of radioactive material on the property. g@. that the contcminated items were actually buried, the NRC staffAssuming performed a hypothetical dose assessment and pathway analysis using the f';< computer modeling program RESRAD hypothetical assessment was based (upon the following assumptions: v y; .%p. - l,qmw. s a 4 s. $'c.> Buried materialionsisted o'f 20 microcuries of americium 241 in (1) the form of contaminated equipment,. metal, and concrete; p ,g, 1? y.
