Prof. Marvin Rapkin Radiation Safety Officer 2641 Kennedy Boulevard Jersey City, New Jersey 07306 Gentlemen:
Subject:
Inspection No. 82-01 This refers to the special safety inspection conducted by Mrs. Teresa Hall Darden of this office on June 1, 1982 of activities authorized by NRC License No.SNM-477 and to the discussions of our findings held by Mrs. Darden with yourself at the conclusion of the inspection.
t I
The area examined during this inspection was limited to a review of those I
activities conducted under your license relating to plutonium / beryllium (PuBe) sealed sources. The Department of Energy has identified PuBe sources with end caps not welded in place and has recommended appropriate nondestructive examination of the outer end cap welds of all PuBe sources. The inspector visually examined the welds of your PuBe sources. No apparent defects were identified; however, the inspector also discussed the advantages of conducting additional nondestructive tests by qualified personnel and appropriate radiation safety precautions during such tests. A wipe sample was taken from each end cap weld area and was analyzed in our Regional Office Laboratory. Our analysis is in agreement with your leak tests results, however, there is evidence of small quantities of removable contamination from two of your sources, identified by you as Source A and Source B with readings of 1.6 x 10-5 microcuries, and 3.4 x 10-5 microcuries respectively. Your leak test report of March 25, 1982 indicates "a slight amount of leakage" present, however, there was no specific source identification.
Sources with traces of removable contamination have, in the past, been found to have improperly welded end caps. Therefore, closer monitoring of your Pu-Be sources is recommended.
This may be achieved by employment of the non-destructive testing technique discussed during the inspection, performance of more frequent leak tests, or return of the sources to the manufacturer via the Department of' Energy for inspection and repair.
You are requested to submit to this office a written statement explaining the methods you will use to monitor your Pu-Be sources.
Within the scope of this inspection, no violations were observed.
In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this letter and your reply will be placed in the Public Document Rocm.
