88-26 TlHANGE UNIT 1 ECCS PIPING CRACKS JUNE 18, 1988 PROBLEM CRACKS IN ,AN UNIS0LABLE ECCS PIPE CONNECTED TO THE RCS HOT LEG.
CAUSE UNKNOWN. .
SAFETY SIGNIFICANCE CIRCUMFERENTIAL FAILURE OF THE LlHE WOULD RESULT IN A 6-INCH LOCA.
DISCUSSION o THE UNIT IS AN 870 MWE, M-TYPE, 3-LOOP PWR IN BELGIUM.
o WHILE CPERATING, A SUDDEN LEAK OCCURRED.
o RADI0 ACTIVITY AND HUMIDITY IN CONTAINMENT INCREASED AND VCT WATER LEVEL DECREASED.
o THE LEAK RATE WAS 6 GPM.
O CRACKS WERE FOUND BY UT AND RT AS SHOWN IN THE ATTACHED DIAGRAM, o NO CRACKS HAVE BEEN FOUND IN SIMILAR PIPING CONNECTED TO THE OTHER 2 HOT LEGS AND TO THE 3 COLD LEGS.
o THIS EVENT IS SIMILAR TO THE FARLEY 2 EVENT OF 12/09/87 EXCEPT:
FARLEY HAD ONE CRACK AND THAT WAS IN THE ECCS LINE CONNECTED TO A COLD LEG.
THE FARLEY CRACK WAS IN A WELD AND THE HEAT AFFECTED ZONE.
THE FARLEY CRACK OCCURRED SI.0WLY.
o AFTER THE FARLEY EVENT, INFORMAT10h NOTICE 88-01 WAS ISSUED ON 01/28/88 AND BULLETIN 88-08 WAS ISSUED ON 06/22/88.
FOLLOWUP o THE BELGIANS:
ARE EXECUTING BULLETIN 88-06.
WILL PROVIDE NRC WITH A REPORT OF THEIR FINDINGS THIS WEEK.
o OEAB HAS PREPARED SUPPLEMENT 1 TO BULLETIN 88-08 TO EMPHASlZE THE NEED FOR ADDRESSEES TO EXAMINE BASE METAL, CONTACT: R. WOODRUFF

PROBLEM
[ STEAM LEAKING INTO EllERGENCY FEEDWATER (EFW) SYSTEM PIPING, CAUSE LEAKING VALVE BONNET AND BACK LEAKAGE THROUGH CHECK VALVE, SAFETY SIGNIFICANCE POSSIBILITY OF EXCESSIVE THERMAL STRESSES IN EFW PIPING, SUPPORTS AhD CONTAINMENT PENETRATION, POSSIBILITY OF WATER HAMMER ON EFW ACTUATION, 1
DISCUSSION o CRYSTAL RIVER IS IN A TWO YEAR FUEL CYCLE WHICH BEGAN LAST FALL.
o IN JANUARY 1986 THE VALVE BONNET OF EFV-18 SEGAN TO LEAX,
! o EFV-43 HAS HAD A HISTORY OF BACK LEAKAGE PROBLEMS, o THE LICENSEE TOUCH TESTED EFW PlPING EACH SHIFT IN ACCORDANCE
! WITH IE BULLETIN 85-01, o TEMPERATURE INCREASE IN EFW PIPING WAS OBSERVED IN MAY 1988, I o BY JUNE 21, 1988 THE BONNET LEAK 0F EFV-18 HAD CHANGED TO STEAM, o PIPING DOWNSTREAM 0F EFV-38 REACHED 400*F - DESIGN IS 110*F.
- i. O PIPING UPSTREAM OF EFV-18 AT AMBIENT INDICATING NO EFV-18 SEAT LEAKAGE, l 0 ONE EFW PIPE ANCHOR FOUND PULLED LOOSE HAS BEEN REPAlRED.
o LICENSEE EVALUATING POSSIBLE TilERMAL DAMAGE TO EFW PIPING, ANCHORS AND PENETRATION - NONE BELIEVED TO HAVE OCCURRED BY LICENSEE, o STAFF CONCERN WITH POSSIBLE WATER HAMMER.
f o TEMPORARY FIX OF PbMPING WATER INTO AFFECTED PIPING WAS EFFECTIVE l IN LOWERING THE TEMPERATURE BELOW 110*F.

88-2G SALEM UNIT 2 LOSS OF VITAL 120 VAC INSTRUMENT BUS AND INVERTER JUNE 22, 1988 PROBLEM LOSS OF THE "2C" VITAL INVERTER BUS CONNECTED TO THE "2C" VITAL
. INSTRUMENT BUS RESULTED IN A REACTOR SCRAM AND SI.
CAUSE ,
LOSS OF THE VITAL INVERTER WAS CAUSED BY A MALFUNCTION IN THE INVERTER'S MASTER FIRING CIRCUIT (A NUMBER OF FUSES WERE BLOWN),
SAFETY SIGNIFICANCE EVENTS INVOLVING VITAL INVERTER FAILURES OFTEN INVOLVE BUS FAILURES, RESULTING IN PLANT SCRAMS AND CHALLENGES TO SAFETY SYSTEMS.
DISCUSSION o JUNE 22, 1988, SALEM UNIT 2 EXPERIENCED A SCRAM FROM 100% POWER DUE TO THE LOW RCP Fl0W TRIP SIGNAL PRESENT.
o THE TRIP SIGNAL RESULTED DUE TO LOSS OF THE VITAL INVERTER SIMULATING THE POSITION OF THE RCP "2B" BREAKER AS "0 PEN".
0 THIS CIRCulTRY DESIGN APPEARS 10 BE LIMITED TO OLDER DESIGNS ON WESTINGHOUSE PLANTS. FOR THIS LICENSEE, AB0VE 36% POWER, A 1 0F 1
-LOGIC WILL GENERATE AN R x TRIP SIGNAL ON LOW REACTOR COOLANT LOOP FLOW.
o SI WAS INITIATED DUE TO:
- 1. TWO CHANNELS OF LOW STEAM LINE PRESSURE FAILED DUE TO FAILURE OF THE ASSOCIATED INVERTER (2/4 LOGIC ACTUATION).
2, 2/4 HIGH STEAM FLOW - CAUSE WAS HIGH STEAM FLON SIGNAL GENERATED DUE TO TRIP TRANSIENT (SETPOINT VARIABLE ON Rx POWER).
o PLANT PRIMARY SIDE WENT SOLID (AS A RESULT OF SI), PORV's LIFTED, RESEATED..
o PEAK PRIMARY PRESSURE REACHED WAS 2395 PSI (PORV SETPOINT - 2335, PZR SAFETY VALVE - 2485).
o RCS TEMP. DID NOT REACH L-TAVG SETPOINT.
CONTACT: J. THOMPSON

50.72 # 12G18 AND MORNING REPORT 06/23/S8
SALEM UNIT 2 .
o PZR CODE SAFETIES DID NOT LIFT, o SECONDARY PORVs ACTUATED, o OPERATORS FOLLOWED THEIR E0P PROCEDURES AND THE PLANT RESPONDED AS EXPECTED.
o S1 WAS TERMINATED 24 MIN. INTO THE EVENT, o THIS EVENT WAS SIMILAR TO THE AUGUST 198G EVENT (SAME INVERTER FAILURE.,DUE TO PERSONNEL ERROR),
FOLLOWUP o THE LICENSEE HAS REPAIRED THE INVERTER AND THE UNIT IS BACK IN POWER OPERATIONS, o Tile LICENSEE IS PERFORMING A POST-TRIP REVIEW 0F THIS EVENT ALONG WITH REVIEWING THE ADEQUACY OF THEIR E0Ps, o EAB IS STILL EVALUATING LICENSEE'S RESPONSE TO THIS EVENT,
