Docket No. 50-483
Union Electric Company
ATTH: Mr. Donald F. Schnell
Vice President - Nuclear
Fost Office Eox 149 - Mail Code 400
St. Louis, M0 63166
Gentlemen:
Enclosed is an addendum to Inspection Report No. 50-483/86014(DRSS)
transmitted by our letter dated July 17, 1986. The addendum consists of
comparisons of results of a liquid sample collected during the inspection,
results of a subsequent spiked liquid sample sent to the environmental
contractor, your Analytic cross check results, and criteria for comparing
analytical measurements.
Because of poor counting statistics Sr-89 and Sr-90 are not compared in
Table 2 (P00L). However, because the contractor reported positive values
when the NRC lab reported not detected," a spiked liquid was supplied to
the contractor through your laboratory. These comparisons (SPLIQ) resulted
in disagreements for both nuclides.
A blind crosscheck sample supplied by Analytics, Inc. was counted by your
laboratory which resulted in agreements for both nuclides.
From discussions
with Mr. C. Graham of your staff it is our understanding that you plan to
obtain the services of another vendor and split samples starting with the first
quarter effluent composite samples to compare against analyses performed in
your laboratory.
In addition you plan to continue the quarterly crosscheck
program with Analytics. These independent program results will be used to
assure the adequacy of your analytical capability in the event you elect to
perform contracted analyses in house in the future.
The crosscheck results will close out Open Item No. 50-483/86014-01.
Please attach the addendum to your copy of our inspection report.
