UNIT 2 ENTERED AN UNUSUAL EVENT DUE TO THE LOSS OF >75% OF THE OVERHEAD ALARM ANNUNCIATORS DUE TO PERSONNEL ERROR.
"MAINTENANCE ACTIVITIES WERE BEING PERFORMED ON THE OVERHEAD ALARM SYSTEM TO REPLACE A BATTERY IN THE 'B' SEQUENCE OF EVENTS RECORDER. THIS ACTIVITY WAS COMPLETED, WHICH THEN REQUIRED THAT DEFAULT DATA BE LOADED INTO THE RECORDER. THIS DEFAULT DATA WAS IMPROPERLY LOADED INTO THE ACTIVE SEQUENCE OF EVENTS RECORDER 'A.' THIS CORRUPTED IT'S DATA WHICH RENDERED THE ENTIRE OVERHEAD ALARM SYSTEM INOPERABLE. THERE ARE NOT PLANT TRANSIENTS IN PROGRESS AND ALTERNATE INDICATIONS FOR THE OVERHEAD ALARM WINDOWS ARE AVAILABLE. ACTIVITIES ARE IN PROGRESS TO RESTORE THE SEQUENCE OF EVENTS RECORDER 'B' WHICH WILL RESTORE THE OPERABILITY OF THE OVERHEAD ALARM SYSTEM. THE ABNORMAL OPERATING PROCEDURE FOR THE LOSS OF OVERHEAD ALARMS HAS BEEN ENTERED AND COMPENSATORY MEASURES ARE IN PLACE THAT PROVIDE ALTERNATE INDICATIONS FOR THE LOSS OF OVERHEAD ALARM CAPABILITY. ALL SAFETY RELATED SYSTEMS AND EQUIPMENT ARE OPERABLE."
THE LICENSEE ESTIMATES APPROXIMATELY 2 HOURS WILL BE REQUIRED TO RESTORE THE OVERHEAD ALARM SYSTEM AT WHICH TIME THEY WILL EXIT THE UNUSUAL EVENT. THE LICENSEE INFORMED STATE/LOCAL AGENCIES AND THE NRC RESIDENT INSPECTOR.
* * * UPDATE 1346 EST ON 2/3/99 FROM SMITH TO S.SANDIN * * *
THE LICENSEE HAS RECOVERED THE "B" SEQUENCE OF EVENTS RECORDER AND IS CURRENTLY RELOADING DATA INTO THE "A" UNIT. THE LICENSEE ESTIMATES THAT BOTH RECORDERS WILL BE RETURNED TO SERVICE BY 1630 EST. THE LICENSEE NOTIFIED THE NRC RESIDENT INSPECTOR. NOTIFIED R1DO(WILLIAMS) AND EO(DENNIG).
* * * UPDATE 1547 EST ON 2/3/99 FROM SMITH TO S.SANDIN * * *
UNIT 2 EXITED THE UNUSUAL EVENT AT 1540 EST AFTER VERIFYING THAT BOTH SEQUENCE OF EVENTS RECORDERS AND THE OVERHEAD ANNUNCIATOR ALARM SYSTEM WERE FUNCTIONING PROPERLY. THE LICENSEE INFORMED STATE/LOCAL AGENCIES AND THE NRC RESIDENT INSPECTOR. NOTIFIED R1DO(WILLIAMS), EO(DENNIG), IRO(GIITTER) AND FEMA(CALDWELL).

UNIT 1 COMMENCED A TECH SPEC REQUIRED SHUTDOWN DUE TO STEAM DRIVEN AUXILIARY FEEDWATER PUMP INOPERABILITY.
"ON FEBRUARY 3, 1999 AT 1200 CST, FORT CALHOUN STATION COMMENCED A TECHNICAL SPECIFICATION REQUIRED SHUTDOWN. THE STEAM DRIVEN AUXILIARY FEEDWATER PUMP HAS BEEN INOPERABLE SINCE FEBRUARY 2, 1999 AT 1225 CST PER TECHNICAL 2.5(1), A 24 HOUR LIMITING CONDITION FOR OPERATION."
A DESIGN MODIFICATION WAS PERFORMED ON THE SYSTEM AROUND JUNE 1998 WHICH INSTALLED AN ACCUMULATOR DESIGNED TO PREVENT TURBINE OVERSPEED AND OVERPRESSURIZATION OF THE DISCHARGE PIPING. DURING SURVEILLANCE TESTING ON FEBRUARY 2, 1999, THE ACCUMULATOR FAILED TO MEET THE MAXIMUM 10 PSI DROP IN 1 HOUR ACCEPTANCE CRITERION. THE ACTUAL PRESSURE DROP WAS MEASURED AS 5.5 PSI IN 30 MINUTES. THE LICENSEE SUBSEQUENTLY REEVALUATED THE BASIS FOR THE DESIGN MODIFICATION AND CONCLUDED THAT A CHOKED FLOW CONDITION WOULD EXIST PRECLUDING TURBINE OVERSPEED. THE LICENSEE IS REVISING THE SURVEILLANCE PROCEDURE AND PREPARING A REQUEST FOR ENFORCEMENT DISCRETION REVIEW BY REGION IV. THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR.

UNIT 1 EXITED THE TECH SPEC REQUIRED SHUTDOWN AT 1424 CST ON 2/3/99. THE STEAM DRIVEN AUXILIARY FEEDWATER PUMP WAS DECLARED OPERABLE FOLLOWING THE COMPLETION OF SURVEILLANCE TESTING. THE UNIT IS CURRENTLY HOLDING POWER BETWEEN 58-60% DUE TO SECONDARY CHEMISTRY REQUIREMENTS. THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. NOTIFIED R4DO(JONES).
