L PS~G Public Service Electric and Gas Company 80 Park Place Newark, N.J. 07101 Phone 201 /430-7000 October 4, l979 Mr. Harold R. Denton, Director Off ice of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Denton:

EVALUATION OF POTENTIAL MA,LFUNCTIONS DUE TO HIGH ENERGY LINE BREAKS SALEM GENERATING STATION UNIT NO. 1 DOCKET NO. 50-272 In response to your letter of September 14, 1979, rega,rding high_.

energy line breaks and their potential impact on non-safety grade control syste~s re~orted in our letter to Mr. Boyce H.

Grie~

dated September 10, 1979, we attach the results of our evaluation.

In summary, three of the four potential interactions (pressurizer power operated relief valves control, main feedwater control and rod control) do not require a,ny a,ction at Salem due to either

  • equipment design, manufacturer's specifications, physical layout, or a combination of the above.

The potential adverse impact from interaction concerning the steam generator power operated relief valves is precluded through procedural changes and opera.tor training as de~cribed in the e~alua,tion.

As a, result of the Th,ree Mile Island accident,.there a,re a signi-ficant number of industry, governmental and regulatory investi-gations underway which are examining the licensing bases and the operating procedures of nuclear generating facilities.

The requirements contained in NUREG 0578 for additional analyses (reference "Section 3.2 Page 17 and Page A-45) encompass potential scenarios consistent with those identified by Westinghouse and ma,de the subject of IE Information Notice 79-22.

We, th,erefore, believe that a,ny additional action you may require as a result of IE Information Notice 79-22 is consistent with, the requiremen~ts of NUREG 0578.
