Bulletin 83-03 Shoreham Nuclear Power Station - Unit 1 Docket No. 50-322

Letter dated April 1, 1983, from R. W.
Starostecki to M.
S.
Pollock
Dear Dr. Murley:
This letter is in response to IEB 83-03, " Check Valve Failures in Raw Water Cooling System of Diesel Generators", and the letter from Mr.
R. W.
Starostecki to M.
S.
Pollock dated April 1, 1983 (reference 1).
There are six service water system diesel generator cooling water check valves at Shoreham.
The Shoreham In-Service Test (IST)
Program for valves includes all six of these valves.
The following is a listing of the valves by mark number and location:
Mark No.

Description Type P41*06V-0014C Diesel 103 Loop B Supply Mission Mfg. Co. 6" #
" DUO-Check" 150 lb insert type check valve Currently, the valve-In-Service Test Program at Shoreham specifies quarterly verification of both forward and reverse flow operability for the check valves indicated above.
This testing complies with IEB 83-03 which requires flow tests to confirm the integrity of valve internals.
Station Procedure SP24.122.01 Rev.
2,
" Service Water Pump Flow Rate Test and Valve Operability Test" describes the-methodology to be used to achieve this.
The procedure is available for on-site review by the NRC Resident Inspector.
Failure of any one of the six check valves would'be determined during the implementation of this Station Procedure.
Lack of normal flow would indicate either of the following:
1.
The check valve, being forward flow tested, has failed to open or has experienced disk / hinge separation and flow is being blocked by the detached disk.
2.
The check valve, being reverse flow tested, has failed to close due to either a separated or stuck disk, causing a significant flow diversion into the idle' service Water Loop.
As requested in IEB 83-03, LILCO will perform the initial valve integrity verification procedures contained in Shoreham Station Procedure SP24.122.01, for the aforementioned six check valves, prior to fuel load.
A report will be submitted to the NRC within ninety (90) days of completion of the results of the station pro-cedure.
The report will include a description of valve failures, if encountered.
To date, there have been no known failures of'the check valves in question.
I LILCO believes the information stated herein to be sufficient to resolve the requirements of IEB 83-03 for the Shoreham Nuclear Power
