Technicd1 Specification Section 6.2.B requires that radiation control procedures shall be maintained, made available tr, all personnel and 5
adhered to.

The licensee's Chemistry Procedure ZCP 531-7, "?erformance Test for the Eberline Model SAC-4 Scintillation Alpha Counter," (hevision 0, May 5, 1985), requires that the SAC-4 be.taken out of service and Cnemistry Supervision be potified if a performance test result falls outside limits defined by the designated logbook.
?
Contrary to the above requiremert: daily performance checks on the SAC-4 during June 1985 were outside the acceptable range on 7 occasions with no evidence that the instrument wqs,taken out of service nor that Chemistry Supervision was notified.

CORRECTIVE ACTION TAKEN AND RESULTS ACHIEVED The Chemistry Supervision emphasized to the Radiation-Chemistry Technicians (RCT's) the importance of properly following the procedure for daily performance checking the SAC-4 instruments. The daily performance checks have been performed in accordance with ZCP 531-7 since the RCT's were spoken to.

. provide documentation that the instrument has been taken out of service and'
. Chemistry Swervision has been notified when -it performs outside' the acceptable range.
-DATE WHEN FULL COMPLIANCE WILL BE' ACHIEVED JThe RCT's were instructed on the need to properly follow the procedure ~on August 27,:1985 and the SAC-4 daily performance checks have been performed in accordance with procedure ZCP 531-7 since then.
