FEB 101968 MEMORANDUM FOR: Charles E. Rossi, Director Division of Operational Events Assessment Office of Nuclear Reactor Regulation FROM: Wayne Lanning, Chief Events Assessment Branch Division of Operational Events Assessment Office of Nuclear Reactor Regulation

SUBJECT:

THE CPERATING REACTORS EVENTS MEETING February 2, 1988 - MEETING 88-05 On February 2, 1988 an Operating Reactors Events meeting (88-05) was held to brief senior managers from NRR, RES, AEOD and Regional Offices on events which occurred since our last meeting on January 26, 1988. The list of attendees is included as Enclosure 1.

The events discussed and the significant elements of these events are presented )

in Enclosure 2. The Enclosure 3 presents a tabulation of long-term followup  !

assignments to be completed and a summary of reactor scrams. No significant j events were identified for input to NRC's performance indicator program. 1 Enclosure 4 provides a 50.72 report tabulation and surrnary for January 25 l through February 2, 1988.

BEAVER VALLEY UNIT 2 LOSS OF ANNUNCIATOR EVENT INITIAL CONDITIONS:

Plant in cold shutdown (Mode 5) repairing pressurizer manway cover leak.

SECUENCE OF EVENTS:

1/28/88 7:08 p.m.- All annunciators went black accompanied by audible alarms.

7:10 p.m.- Two operators dispatched to investigate, find fire in IAK M1 expansion cabinet No. 5, two levels below control room.

(About) 7:15 p.m. - Fire Out.

7:20 p.m. - ALERT declared IAW Emergency Plan (sustained loss of annunciators).

10:45 p.m.-

Majority of annunciators restored,. Terminated ALERT.

2/1/88 All damage to cabinet repaired.

Region I specialist onsite to provide independent review of licensee action.

IMPACT:

Minimal; normal control room parameters never lost. Would necessitate additional operators to monitor insteumentation.

H.B. ROBINSON UNIT 2 POTENTIAL LOSS OF SAFETY INJECTION CAPABILITY PROBLEM A SINGLE FAILURE IN THE ONSITE ELECTRICAL SYSTEM WOULD PREVENT THE AVAILABILITY OF THE SAFETY INJECTION (SI) FUNCTION.

CAUSE LOSS OF EITHER TRAIN OF D.C. POWER WOULD PREVENT CONTROL FUNCTIONS NECESSARY FOR SI OPERABILITY, SIGNIFICANCE LOSS OF Si DURING LOCA.

DISCUSSION o LICENSEE, IN RESPONDING TO AN ELECTRICAL SYSTEMS BRANCH QUESTION-AIRE, CONDUCTED A REVIEW OF THE IE DISTRIBUTION SYSTEM INCLUDING l D.C. CONTROL POWER, o LICENSEE INITIALLY DETERMINED THAT FAILURE OF THE "B" TRAIN D.C. l POWER SUPPLY WOULD PREVENT THE "B" AND "C" SI PUMPS FROM RECEIVING MOTIVE POWER. i o THIS PLACED THE UNIT IN AN UNANALYZED CONDITION AND TECH. SPEC. l REUUIRED SHUTDOWN WAS COMMENCED.

o LICENSEE EXITED T/S SHUTDOWN WHEN CERTAIN EQUIPMENT AND PROCEDURAL i CHANGES WERE IMPLEMENTED. l 0 LICENSEE'S PROPOSED CHANGES WERE FOUND TO BE INADEQUATE. i

. o STAFF QUESTIONING SURFACED THE FACT THAT THE FAILURE OF "A" TRAIN  !

D.C. CONTROL' POWER WOULD ALSO RESULT IN THE LOSS OF THE SI FUNCTION.

o UNIT IS CURRENTLY SHUTDOWN.

FOLLOWUP l 0 REGION IS FOLLOWiliG LICENSEES ACTIONS.

o ELECTRICAL SYSTEMS BRANCH WILL REVIEW LICENSEE'S CORRECTIVE ACTIONS.

o EAB STAFF HAS NOTIFIED TURKEY POINT PROJECT MANAGER OF THE PROBLEM.
