malfunctioning offgas system as a l
result of partial loss of Instrument

NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT #2 NARRATIVE OF OPERATING EXPERIENCE Nine Mile Point Unit 2 operated with a capacity factor of 44.21% (MDC - net) and an availability factor of 55.2% during the month of May 1990.
On May 14. Operations at Nine Mile Point Unit 2 initiated a manual reactor scram by placing the mode switch in " SHUTDOWN" in response to loss of Main Condenser vacuum due to a malfunctioning offgas system caused by failure of an Instrument Air System (IAS) pipe.
The unit remained shutdown (off-line) until May 28.
(Refer to LER 90-09 for details).
There were no challanges to safety relief valves during this reporting period.
