SUBJECT:
THE OPERATING REACTORS EVENTS MEETING April 19, 1989 - MEETING 89-16 On April 19, 1989, an Operating Reactors Events meeting (89-16) was held to brief senior managers from NRR, AE00, RES, Comission Staff, and Regional Offices on events which occurred since our last meeting on April'12, 1989.
The list of attendees is included as Enclosure 1.
The events discussed and the significant elements of these events are presented in Enclosure 2. A sumary of reactor scrams for the week ending 04/16/09 is presented in Enclosure 3. One significant event was identified for input into the NRC performance indicator program.

DISCUSSION o REACTOR WAS AT 25% POWER IN ACCORDANCE WITH POWER ASCENSION PROGRAM AFTER EXTENDED OUTAGE.
o TEST IS PERFORMED EVERY 6 MONTHS. DONE "SUCCESSFULLY" LAST TIME (10/05/88); REACTOR WAS NOT OPERATING OR PRESSURIZED.
O APPR0XIMATELY 100 GALLONc 0F WATER WAS DISCHARGED FROM RELIEF VALVE THROUGH DRAIN LINE T0 SUMP AND AREA.
O FIVE WORKERS BECAME SLIGHTLY CONTAMINATED - SH0ES AND ONE HAND.

PROBLELi HIGH TEMPERATURE IN UPPER PORTION OF DRYWELL.
LESE INADECUATE INSULATION AND/0R VENTILATION RESULTED IN RADIANT HEAT.
SAFETY SIGNIFICANCE THE UPPER DRYWELL AREA C0tlTAINS APPROXIMATELY 150 CABLES OF WHICH ABOUT 50 PER CENT ARE SAFETY-RELATED.
1)lSCUSSION o ON FEBRUARY 28, 1989, LICENSEE NOTICED HEAT DAMAGE TO CABLES Ifl THREE CONDUITS LOCATED IN UPPER DRYWELL.
o ON MARCH 2, 1989, LICENSEE DISCOVERED DURING A FUNCTIONAL TEST THAT TWO MECHANICAL SNUBBERS IN THE SAME AREA HAD APPARENT HEAT LAMAGE.
o ON APRIL 6, 1989, LICENSEE NOTIFIED NRC.
0 ESTIMATED THAT CABLES WERE EXPOSED TO TEMPERATURES IN EXCESS OF 300*F. SNUBBERS MAY HAVE BEEN EXPOSED TO TEMPERATURES AS HIGH AS 400-500*F.
o EQUIPMENT QUALIFICATION TEMPERATURES FOR CABLES IS 195'F AND FOR SNUBBERS, 300*F.
o AFFECTED CABLES INCLUDES SRMs, IRMs, SRVs AND HYDROGEN IGNITERS.
o LICENSEE PLANS TO REPLACE CABLES THAT SHOW VISUAL DAMAGE: 15 0F 73 SAFETY-RELATED CABLES AND E2 0F 79 NON-SAFETY-RELATED CABLES.
o LICENSEE PLANS TO JUSTIFY NOT REPLACING ALL THE CABLES BY ANALYZING THE MECHANICAL PROPERTIES OF THE CABLES (AN UNIQUE APPROACH).
O GE ISSUED RICSIL NO. 041, " EXCESSIVE MARK III DRYWELL TEMPERATURE",
MARCH 31, 1989 IN RESPONSE TO THIS EVENT. RICSIL MENTIONS SRVs, MSIVs, AND WATER LEVEL MEASUREMENT SYSTEM.

' SAFETY SIGNIEJCANCE REACTOR C00LDOWN RATE AVERAGED 200*F/ HOUR DURING FIRST HOUR; THIS COULD CAUSE THERMAL STRESS TO THE REACTOR VESSEL AND INTERNALS. i DISCUSSICE 0; PLANT WAS'IN STARTUP (10% POWER) AFTER PERFORMING MAINTENANCE ON ELECTROMATIC RELIEF VALVE IC.
o POST-MAINTENANCE TESTING OF THE VALVE WAS REQUIRED; IT WAS DECIDED l
.T0 PERFORM 6 MONTHS REQUIRED SURVEILLANCE ON THE REMAINING ELECTRCMATIC VALVES.
o VALVES IC, lA, AND 1B WERE TESTED SUCCESSFULLY. AT 3:27 A.M.
VALVE ID WAS OPENED AND REMAINED IN THE OPEN POSITION; THE VALVE WOULD NOT SHUT DESPITE REPEATED ATTEMPTS.
O LICENSEE SCRAMMED REACTOR AT 3:30 A.M. PER PROCEDURES AND DECLARED AN UNUSUAL EVENT.
o MAXIMUM SUPPRESSION POOL TEMPERATURE WAS 100*F AT 5:12 A.M.
o REACTOR C00LDOWN RATE AVERAGED 200*F/ HOUR DURING THE FIRST HOUR (FIGURES 1 & 2), AND ABOUT 115'F/ HOUR DURING THE FIRST TWO HOURS. '
o GE PRELIMINARY ANALYSIS INDICATES THAT THIS THERMAL CYCLE WILL NOT HAVE-AN IMPACT ON PLANT LIFE.
O CAUSE OF THE FAILURE IS SUSPECTED TO BE EROSION IN THE PILOT VALVE (FIGURE 3). ,
o THE ENTIRE VALVE HAS BEEN REPLACED; THE OLD VALVE WILL BE DECONTAMINATED AND DISASSEMBLED FOR INSPECTION.
