SUBJECT:
Waterford SES Unit 3 Docket No. 50-382 Engineered Safety Features Actuation System (ESFAS)
Subgroup Relay Testing Meeting - 4/26/84
REFERENCE:
LP&L Letter W3P83-2273 dated July 21, 1983
Dear Sir:
On Thursday, April 26, 1984, a meeting was held with the Instrumentation and Controls Branch (ICSB) to discuss ESFAS subgroup relay testing. The above referenced letter detailed which subgroup relays could not be tested during reactor operation without adverse and unwarranted impact on plant safety and/or operability. The letter also identified which subgroup relays are tested duri'1g the semi-annual at power Channel Functional Test (Technical Specification 4.3.2.1) and clarified component actuations.
The meeting involved a step-by-step review of'the subgroup relays and resulted in ICSB's concurrence of Waterford 3's ESFAS subgroup relay test program. Please find attached a listing of subgroup relays that are not tested at power but are tested during applicable COLD SHUTDOWN periods. This listing reflects current design and updates the referenced letter as was concurred at the meeting.
Should there be any further concerns, please do not hesitate to contact us.
Yours very truly,
[
