SUBJECT:

EMERGENCY TECHNICAL SPECIFICATION CHANGE - SAFETY FEATURES 7

ACTUATION SYSTEM INSTRUMENTATICN j Re: Da'vis-Besse Nuclear Power Station . .

By letter dated March 31, 1987, you requested an emergency Technical
Specification (TS) change which would modify _the number of Safety Features-Actuation System (SFAS) logic sequencer channels for Emergency Diesel -

Generator loading which is required to be operable. LThere-are four (4) such .

logic sequencer channels as indicated in TS Section 3.3.2.1. Table 3.3-3 and the existing TS requires all four channels tolbe operable. Your March 31,

. 1987 letter proposes- to change the minimum number of sequencer channels required to be operable from four (4) to three (3).,

y. ,

We have reviewed your evaluation and justification provided in your March 31, 1987 submittal and find them acceptable. ,This letter confirms the verbal-i granting of a temporary waiver ~of compliance,=.as discussed with you on March 30, ,

1987, to change the minimum number'of sequencer channels required to be R

, operable from 4 to 3, as indicated in the enclosediTS.page. This-temporary.

waiver of compliance will be in effect until April 3,~1987,'while we complete' '

i the processing of your _ amendment request.

Sincerely, . .
