CEA INADVERTENTLY WITHDRAWN DilRING REFUELING l APRIL 23-24, 1988 PROBLEM l'
l o ON APRIL 23, 1988 (0530) THE LICENSEE NOTICED THAT ONE OF THE FIVE-FINGERED CONTROL ELEMENT ASSEMBLIES (CEA's) WAS STILL LATCHED i
TO THE UPPER GUIDE STRUCTURE ASSEMBLY (UGSA) WHILE LIFTING THE UGSA '
FROM THE VESSEL.
! CAUSE l UNKNOWN SAFETY SIGNIFICANCE WORST CASE SCENARIO IS A DROPPED CEA OVER THE CORE. NO REACTIVITY CONCERN DUE TO HEAVILY BORATED CONDITIONS DURING REFUELING DISCUSSION o USING A SPECIAL TOOL AND CHAIN HOIST, THE LICENSEE MANAGED TO PULL j
THE CEA EXTENSION SHAFT INTO THE UGSA WITH 15 INCHES EXTENDING OUT l THE BOTTOM 0F THE UGSA. I o LICENSEE USED A SUBMARINE-EQUIPPED CAMERA TO VERIFY WHICH CEA WAS l
STILL LATCHED.
l 0 THE LICENSEE MANAGED TO MOVE THE UGSA OVER THE REACTOR VESSEL FLANGE i AND TO THE REFUELING WATER POOL AND DE-LATCHED THE CEA.
O CEA REMAINS AT THE BOTTOM 0F THE P0OL UNTil 0FFLOADING OF FUEL IS COMPLETE. i l
FOLLOWUP o LICENSEE PLANS TO VISUALLY INSPECT CEA FOR DAMAGE AND TO
, SEE IF THEY ARE ABLE TO REUSE THIS CEA. ;
o THIS HAS HAPPENED AT OTHER PLANTS (CRYSTAL RIVER AND ANO-1).

PROBLEM LOOSE PARTS MONITORING SENSOR PICKED UP NOISE IN THE "B" RECIRCULATION LOOP. '
CAUSE SOURCE IS THOUGHT TO BE A VIBRATING PART IN FLOW CONTROL VALVE.
1 SIGNIFICANCE POTENTIAL TO DAMAGE FLOW CONTROL VALVE. ALSO PART CAN DISENGAGE AND I
DAMAGE RECIRCULATION PUfP, JET PUMP, VALVES, FUEL RODS, OR ANY COMPONENT OR EQUIPMENT THE PART COMES IN CONTACT WITH. r DISCUSSION o MAINTENANCE WORK PERFORMED ON FLOW CONTROL VALVE LAST REFUELING t OUTAGE. i
- o ON 04/09/88 INCREASED POWER FROM 70% TO 100%.
1 o LOOSE PARTS MONITORING SENSORS PICKED UP NOISE IN "B" RECIRCULATION LOOP.
i o TWO SENSORS: ONE LOCATED 20 FEET DOWNSTREAM 0F FLOW CONTROL VALVE ,
AND ONE LOCATED 20 FEET DOWNSTREAM 0F SUCTION ISOLATION VALVE.
i o ON 04/20/88 NRR WAS INFORMED.
o B&W REPRESENTATIVES ON SITE REFINING ANALYSIS OF NOISE.
j o CONCLUSIONS ARE:
l
) (A) NOISE COMING FROM FLOW CONTROL VALVE IN PIPING 0F "B" RECIRCULATION LOOP.
(a) SOUNDS LIKE METAL-TO-METAL CONTACT, j o LICENSEE HAS CHECKED ALL RECIRCULATION PUMP PARAMETERS AND FOUND j THEM NORMAL.
, o LICENSEE HAS VARIED FLOW IN RECTRCULATION PUMP SEAL, RUCU SYSTEM AND CRD. ALSO PERFORMED JET PUMP Sl!RVEILLANCE TESTING. NOISE j REMAINED THE SAME.
CONTACT: T. GREENE i i
REFERENCE:
MORNING REPORT 04/21/88 '
o LICENSEE REDUCED FLOW IN "B" RECIRCULATION LOOP TO 85%, NOISE GREATLY REDUCED.
o LICENSEE HAS REQUESTED GE TO DETERMINE WHAT ADDITIONAL INSTRUMENTS ARE NEEDED TO MONITOR FLOW CONTROL VALVE AND ASSESS POSSIBl.E CAllSES OF NOISE IN FLOW CONTROL VALVE.
