January 15, 1987 Docket No. 50-298 Mr. George A. Trevors, Division Manager for Nuclear Support Nebraska Public Power District P.O. Box 499 Columbus, Nebraska 69601

Subject:

Technical Specifications for Alternate Shutdown Panels Re: Cooper Nuclear Station (CNS)

During the Cycle 10 refueling outage, 10 CFR 50.48 (Appendix R) alternate shutdown modifications were performed at CNS. In accordance with Generic Letter 81-12, a Technical Specifications amendment request should be i forthcoming to reflect the newly added equipment. The enclosure is forwarded for your guidance in preparing an amendment request.

It is noted that CNS does not have a Dedicated Shutdown System. Accordingly, the guidance relating to a DSS diesel generator and battery bank is not applicable to CNS.

The staff considers three months prior to Beginning of Cycle 12 a reasonable period of time for the District to prepare and submit an amendment request.

Sincerely, N. M William 0. Long, Project Manager BWR Project Directorate #2 Divison of BWR Licensing

PLANT SYSTEMS BASES 3/4.7.13 ALTERNAT!JE/ DEDICATED SHUTDOWN SYSTEM l The OPERALILITY of the ASS / DSS ensures that a fire will not preclude achieving safe shutdown. The ASS / DSS equipoent are independent of areas where a fire could damage systems nornelly used to shutdown the reactor. This capability is consistent with GDC 3 and 10CFR50, Appendix R.

The equivalent shutdown capability provided when the ASS / DSS is inoperable depends on the specific equipment involved and, therefore, should be sufficient to assure that the intended shutdown actions can be accomplished, or that fires can be reasonably precluded during that time for which ASS / DSS equipment would otherwise be required, consistent with the ASS / DSS design basis. Any temporary procedures or special fire watch patrols established to provide this equivalent capability should be reviewed by the (PORC) ard approved by the (station superintendent) prior to implementation.

3/4.7.14 PORTABLE FIRE EXTINGUISHERS .

The portable fire extinguishers are the first line of fire defense and are most effective when fires are in their early stages of development. Portable extinguishers provide the capability to protect safety-related equipment from fires in their incipient stages, but must be properly distributed throughout the plant and maintained in good operating condition to be effective. When

- an extinguisher is inoperable, it should be promptly repaired or replaced.

3/t. 7.15 EMERGENCY LIGHTING UNITS The 8-hour emergency lighting units are provided in areas needed for operation of safe shutdown equirment and in access a.id egress routes thereto.

This equipment provides illuminat'cn for operators to manipulate required equipment concurrent during plant emergency shutdown operations with the lost of the normal illumination within the area. This equipment should be properly maintained and if inoperative should be promptly repaired or rep 1 aced consistent with the defense-in-depth philosophy.
