OPS~G Pub~ic Service Electric and Gas Company P.O. Box 236 Hancocks Bridge, New Jersey 08038-0236 Nuclear Business Unit AUG 111995 LR-N95123 United States Nuclear Regulatory Commission Document Control Desk Washington, D.C. 20555 Gentlemen:
CANCELLATION OF PREVIOUS EVENT INITIAL NOTIFICATION VIA THE EMERGENCY EVENT NOTIFICATION SYSTEM SALEM GENERATING STATION FACILITY OPERATING LICENSE NO. DPR-70 AND DPR-75 DOCKET NO. 50-272 AND 50-311 UNITS NO. 1 & 2 Initial notification pursuant to the requirements of the Code of Federal Regulations 10 CFR 50.72(b) (2) (i) was performed on June 22, 1995 at 1500 Hours EST.
The event identified in this notification was described as a Design Basis Change during SSE and Tornado conditions, resulting in both Salem Units operating in an unanalyzed condition.
This notification referenced Westinghouse Bulletin 89-02 which changes the design use of brackish service water as a source of cooling water for the steam generators.
Westinghouse Bulletin 89-02, in part, states that steam generator tube perforation would occur in "approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />" with a 4000ppm chloride solution (the average chloride content for the Delaware River).
Investigation of the conditions and events of this incident has determined this notification was conservatively performed to ensure compliance to the requirements of the above Code of Federal Regulations.
Further investigation into Westinghouse Bulletin 89-02 concerning limitations associated with the use of service water as heat sink after a design basis event, indicates the initial data was misinterpreted and that no degradation would occur.
This determination is based on the analysis submitted by MPR Associates Inc. dated July 20, 1995, which states that no through wall pitting would occur during any period of less than one week exposure to saline river water, which is well after the plants would be taken into a cold shutdown condition.
