o INVESTIGATE CAUSE OF LOW AIR PRESSURE.
o CONSIDERATION SHOULD BE GIVEN TO OPERATING MSV-14 LOCALLY USING INSTRUCTIONS GIVEN IN OP-608.
DISCUSSION:
TURBINE BYPASS VALVES ARE AIR TO OPEN AND AIR TO CLOSE, THEY ARE DESIGNED TO FAIL CLOSED ON LOSS OF INSTRUMENT AIR. AT = 60 PSIG DECREASING INSTRUMENT AIR PRESSURE, TRIP VALVE WILL CLOSE TURBINE BYPASS VALVE; AT = 72 PSIG INCREASING INSTRUMENT AIR PRESSURE THE TRIP VALVE WILL RESET AND THE TURBINE BYPASS VALVE WILL REOPEN.

o DURING REDUCED Tave OPERATIONS AT THE END OF FUEL CYCLE LIFE (EOL) THIS ALARM IS ACCEPTABLE PROVIDED > 44' MAINSTEAM SUPERHEAT IS MAINTAINED.
t DISCUSSION:
THE BTU LIMIT ALARM INDICATES CONDITIONS WHERE EITHER, THE ENERGY INPUT TO THE OTSG IS NOT SUFFICIENT, OR FEEDWATER/0TSG TEMPERATURE / PRESSURE ARE INADEQUATE TO MAINTAIN REQUIRED SUPERHEAT TO OPERATE THE MAIN TURBINE.
WITHOUT SUFFICIENT SUPERHEAT THERE IS A RISK OF CARRYOVER DAMAGE TO i
