Frederick W. Schneider Vice President Public Service Electric and Gas Company 80 Park Place Newark, N.J. 07101 201/622-7000 Production November 9, 1976 Mr. James P. O'Reilly, Director U.S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region 1 631 Park Avenue King of Prussia, Pennsylvania 19406
Dear Mr. O'Reilly:
NRC IE CIRCULAR 76-02 "RELAY FAILURES -
WESTINGHOUSE BF (ac) AND BFD (de) RELAYS" NO. 1 UNIT SALEM NUCLEAR GENERATING STATION Pursuant to NRC IE Circular 76-02 received August 23, 1976 we offer the following:
BF (ac) Type Relays
- 1.
There are four (4) channels in the Radiation Monitoring System, Salem No. 1 Unit, which utilize BF (ac) relays.
All of these channels were initially calibrated and functionally tested during the period of July -
- August,
- 1976 respectively.
The circuit designs are such that these relays must function properly in order to perform a satisfactory test.
- 2.
In recognition of the subject circular, Design Change Request (DCR) No. PD-0017 was initiated by the Salem Electric Production Department on September 14, 1976, requesting that PSE&G Engineering specify an acceptable substitute for the existing BF (ac) relays.
Mr. J. P. O'Reilly 11/09/76
- 3.
Struthers-Dunn Type 219-DXBF relays have been selected as the replacement and are currently on order.
Completion of this replacement activity is anticipated by January, 1977.
BFD (de) Type Relays PSE&G Engineering has determined that nine (9) BFD (de) relays were supplied by the NSSS Supplier in the Liquid Waste Disposal System.
As a result, Design Change Request (DCR) No. ED-0009 was initiated to replace the BFD relays in the L.W.-D. system with Struthers-Dunn Type 219-DXBF relays which have been ordered.
It is also anticipated that this change will be completed by January, 1977.
