CAUSE UNDER INVESTIGATION, SAFETY SIGNIFICANCE POSSIBILITY RELEASE FISSION GASES TO THE ENVIRONMENT, DISCUSSION o THE UNIT IS A 900 MWE,W-lYPE, 3-LOOP PWR IN SPAIN, o BEGAN OPERATION IN 1981, o AT 1:10 A.M., WHitt UPERATING AT 100%, A LtAK WAS DETECTED IN STEAM GENERA 10K "a".
RATE RADIATION NONITOR COUNT RATES IN THE BL0kDOWN INCREASED 4
FHOM 7C0 CPM TO 1 X 10 CPM IN 10 MINUTES, o Al 2:20 A.M. THE LEAK WAS ESTIMATED AROUND 1 GPM (IECH, SPEC, LIMIT),
o UNUSUAL EVENT WAS DECLARED PER Tile EMERGENCY PLAN AT 2:20 A.M.
o SUBSEQUENTLY THE UNIT DECREASED POWER AT A RATE OF 8 MW/ MIN, o AT 4:20 A.M. THE UNIT WAS DISCONNECTED FROM THE GRID, o At 4: 30 A.M. THE REACTOR WAS SUBCRITICAL, o AT 4:36 A.M. THE PRIMARY AND SECONDARY PRESSURE WERE EGUAll2ED, THE STEAM GENERATOR WAS ISOLATED, AND THE UNUSUAL EVENT WAS TERMINATED, o DURING REFUELING IN FEBRUARY 1988, STEAM GENERATOR TUBES WERE INSPECTED AND NOTHING ABNORMAL WAS DETECTED, o AFTER THE EVENT, SUBSEGUENT INSPECTIONS OF THE TUBES WERE PERFORMED.,

THE CRACK WAS 1" LONG.
AXIALLY ORIENTED AT THE FIRST SUPPORT PLATE IN STEAM GENERATOR HOT SIDE,
- THE CRACK ORIGINATED ON THE SECONDARY SIDE,
- A THROUGH-WALL PINHOLE SIZE PERFORATION WAS ESTIMATED, o TWO TUBES WILL HAVE SECTIONS REMOVED T0 INVESTIGATE THE CAUSE (THE LEAKING TUBE AND ANOTHER WITH 90% PENETRATION),

PIPING, CAUSE Alk BINDING OF THE HPSI PUMP, SAFETY SIGNIEICANCE A WATERHAMMER COULD CAUSE A PlPE RUPTURE OR ECCS DEGRADATION, DISCUSSION o PLANT IN MODE 5 HPSI PUMP USING RWST AS SUCTION SOURCE WAS STARTED TO INCREASE REACTOR COOLANT VOLUME, o PLANT WAS UNDER60 LNG AN INTEGRATED LEAK RATE TEST (ILRT) AT THE TIME AND HAD THE CONTAINMENT PRESSURIZED.
o SUMP ISOLATION VALVES WERE NOT FULLY CLOSED, ALLOWING AIR TO ENTER THE HPSI SUCTION PIPING, o THE PUMP BECAME AIR BOUND, HOWEVER, ONE OR MORE SLUGS OF WATER TRTVELLED DOWN THE DISCHARGE PIPING BEFORE THE PUMP WAS SIUPPEU, o ShuBBERS AND PIPE HANGERS DO NOT APPEAR TO BE DANAGED, o LICENSEE WILL PERFORM COMPLETE PM ON AFFECTED PUMP PRIOR TO RESTART, o NORMAL PRACTICE FOLLOWING AN ILRT IS TO VENT ALL PIPING AND PUMPS S0 NO PUMPS WOULD BE AIR BOUND OR AIR ENTRAINED IN PIPING DURING NORMAL OPERATION, FOLLOWUP NONE ,
