Dear Mr. Schwencer:

RESPONSE TO NRC REQUEST FOR INFORMATION DIESEL GENERATORS -

SALEM GENERATING STATION - UNIT NO. 1 DOCKET NO. 50 - 272 In response to your letter of June 29, 1978, which was received on July 3, 1978, we offer the following information concerning\-~

the diesel-generator alarm and control circuitry: ~

Relay Test Switches ~*

~*

~.

Test switches DS-15, DS-8, 24-86B-2, and 24-86BD-2 are under c.~*

administrative control as described in the previous response ~:;~

to the NRC concerning diesel-generator alarms. These switches will be modified so that whenever contacts of the switch are operated which could prevent the automatic start of the die-sel-generators, an alarm will appear on the auxiliary annun-ciator. The alarm will be appropriately worded to alert the operator of such a condition. Separate alarms will be pro~

vided for each diesel-generator.

Manual Shutdown Lockout Relay Salem does not incorporate a manual shutdown lockout relay of the type described in the NRC letter. Manual lockout of the diesel-generators at Salem is accomplished with a lock-out switch which was described in the previous response to the NRC on this subject. Appropriate alarms are provided to alert the operator of operation of the switch.

If you have further questions on the above subject, please do not hesitate to contact us.

Very truly yours,

))
