-PRELIMINARY NOTIFICATION OF EVENT OR UNUSUAL OCCURRENCE--PNO-I-87-39 This preliminary notification constitutes EARLY notice of events of POSSIBLE safety or public interest significance. The information is as initially received without-
. verification or evaluation, and is basically all that is known by t b Region I staff on this'date.
l Facility: Licensee Emergency Classification:
Indian Point Unit 2 Notification of Unusual Event Ccnsolidated Edison Co. of NY Alert Buchanan, New York Site Area Emergency General Emergency 5Am X Not Applicable
Subject:
Single Failure in Auxiliary Feedwater Initiation Circuit At 10:15 a.m. on April 30, 1987, the licensee identified a potential single failure which would prevent an automatic start of both motor-driven Auxiliary Feedwater Pumps !
en receipt of valid loss of main feedwater or low-low steam generator level signals. l N2ither the manual start nor the automatic sequencing on safety injection are affected. The identified problem also does not prevent automatic start of the steam-driven auxiliary feedwater pump.
The start failure would occur if relay contacts which provide an inhibit signal to both i cotor driven pumps fail in the open position. This inhibit signal is generated in '
the event safety injection has initiated and is provided to prevent immediate l auxiliary feedwater pump start when load sequencing is the intended response. The !
relay contact failing open would also require the associated inhibit relay to be cnergized.
Th2 licensee is modifying the circuit to use independent relays for each motor-driven auxiliary feedwater pump.
This single failure has generic implications. Indian Point Unit 3 reported a similar, but not identical, situation in the auto-start circuitry on April 30, 1987.
The state of New York has been informed.
