The events discussed and the significant elements of these events are presented in Enclosure 2. Enclosure 3 presents a report-to-date of long-term followup assignments and a sumary of reactor scrams for the week ending 05/07/89.
Two significant events were identified for input into the NRC performance indicator program.

DISCUSSIQB o ON MAY 4, 1989, WHILE IN MODE 6, THE LICENSEE DETERMINED THAT APPROX-22 0F 12C PRESSURIZER HEATER SLEEVES HAD BORIC ACID BUILDUP IN UNIT 2.
c ON MAY 5, 1989, INITIATED PLANT SHUTDOWN OF UNIT 1 TO MODE 5.
c VISUALLY INSPECTED UNIT I FOR BORIC ACID BUILDUP, NONE FOUND.
o UNIT'1 IS PRESENTLY SHUTDOWN.
o AS OF MAY 9, 1989, LICENSEE IS REMOVING INSULATION AR0UND PRESSURIZER TO MAKE THE AREA ACCESSIBLE FOR DETAILED INSPECTION.
SIMILAR EVENT AT ARKANSAS UNIT 2 ( APRIL _2L_JSBZ.)
o THE LICENSEE DISCOVERED A NON-IS0LABLE LEAK AND PITTING AT THE BOTTOM OF THE PRESSURIZER, o THE CAUSE OF THE LEAKAGE IS BELIEVED TO BE POOR WELDING BY THE CONTRACTOR (CE), AND EXPOSURE OF ELECTRICAL INSULATION WITHIN THE SHEATH TO WATER WHICH RESULTED IN EXPANSION OF THE INSULATION AND AXIAL CRACKS IN THE PENETRATION SLEEVE AND SEAL WELD. THIS EVENT LED TO STRESS CORROSION FAILURE OF THE HEATER SHEATH MANUFACTURED FROM INCONEL.

DISCUSSJDB o ON APRIL 23, 19ES, DURING HOT FUNCTIONAL TESTING OF THE AUXILIARY FEEDWATER (AFW) SYSTEM, HOT STEAM GENERATOR INVENTORY FLOWED INTO AFW SYSTEM PIPING.
o A COMBINATION OF OPERATOR ERROR AND MECHANICAL FAILURES ,
CONTRIBUTED TO THIS EVENT.
o MAY 3, 1989, POST-EVENT TESTING HAS DETERMINED THAT THE CHECK VALVES ASSOCIATED WITH THE DISCHARGE HEADERS FOR BOTH MOTOR DRIVEN AUX FEEDWATER PUMPS (MDAFWP) AND TURBINE DRIVEN AUXILIARY FEEDWATER PUMPS (TDAFWP) ARE INEFFECTIVE AS FLOW OR PRESSURE B0UNDARIES.
o THE FEED LINE CHECK VALVES FOR EACH STEAM GENERATOR WERE SATISFACTORILY TESTED FOR BACKLEAKAGE, INDICATING ONE OR BOTH VALVES IN EACH SERIES OPERATED AS DESIGNED.
o LICENSEE'S VIEW IS THAT THE FLOW PATH FOR STEAM GENERAT9R BACKLEAKAGE MAY HAVE INVOLVED THE MAIN FEEDWATER BYPASS ISOLATION VALVE AND THE FEEDWATER PRE-HEATED ISOLATION VALVE.

o THE PLANT IS li, COLD SHUTDOWN. ON THURSDAY, MAY 11, 1988, THE !
LICENSEE WILL BRIEF THE REGION AND OSP PERSONNEL ON THEIR FINDINGS. i o FOLLOWING ADDITIONAL TESTING, CHECK VALVE DISASSEMBLY WILL COMMENCE l THIS WEEKENL (MAY 13 AND 14, 1589) AT THE EARLIEST. )
