NL&P/CGL Docket Nos.

License Nos.

93-265A RO' 50-280 50-281 DPR-32 DPR-37 During a June 16, 1994 conference call, the N RC requested clarification of the alternate indication information provided by our May 24, 1994 letter (Serial No.93-265).

Specifically, the requested clarification was with regard to identification of additional indicator designations and equipment mark numbers.

Attached is a revised version of Attachment 3 from our May 24, 1994 letter including the requested clarification.

Also attached are pages excerpted from the current emergency procedures referenced in Attachment 3.

If you have questions or require additional information, please contact us.

PAGE 1 of 2 NOTE:

The Auxiliary trip relay actuates when any of the following occur:

Overspeed trip Loss of Generator field

  • Differential fault on EDG output Overcurrent trip on output breaker Manual stop
  • Actuation of the auxiliary trip relay prevents the EDG output breaker from closing and locks out the EDG start circuit. After the initiating signal has cleared, the auxiliary trip relay must be reset to allow restarting the EDG.

An overspeed condition will immediately shutdown the EDG and lockout the start circuits until the overspeed lever is reset.

A differential fault or overcurrent trip will put the EDG into the cooldown cycle.

IF ( )J Bus is deenergized, THEN strip loads IAW Attachment 3 (lJ Bus) or Attachment 4 (2J Bus).

~: A differential fault will trip the EDG Exciter Field breaker.
