DOCKET NOS. 50-445 AND 50-446 DIESEL GENERATOR LUBE OIL SUMP TANK FOOT VALVES SDAR: CP-86-31 (INTERIM REPORT)
Dear Mr. Johnson:
On August 22, 1986 we notified you of a reportable item involving the possible failure of the rubber facing on foot valves mounted in the diesel generator lube oil sump tank (see TXX-4975). This is a follow-up interim report on a reportable item under the provisions of 10CFR50.55(e) and is provided to status the implementation of corrective actions.
New Viton liners have been purchased and received at the CPSES site.
Unit I work orders have been issued and installation is expected to be complete by December 5, 1986.
Unit 2 replacement liners are scheduled for installation after lube oil flush of the diesel generator system which is tentatively scheduled for completion by March 1, 1987.
We will submit our next status report no later than March 27, 1987.
Very truly yours, 7(M W. G. Counsil j
