SPDS WILL BE DE-ENERGIZED FOR MORE THAN 8 HOURS DUE TO REFUELING OUTAGE ACTIVITIES

"At 22:10 on March 6, 2004 the Unit 1 Safety Parameter Display System (SPDS) was deenergized during planned refuel outage activities. It has been determined that it will not be restored within the required eight hours. Currently, restoration is scheduled for March 7, 2004 at 17:00. All required instrumentation is available in the control room.
Since the Unit 1 SPDS computer system will be unavailable for greater than 8 hours, this is considered a Loss of Emergency Assessment Capability and therefore reportable under 10CFR50,72(b)(3)(xiii). Unit 1 is currently in Mode 5 for the planned 13th Refuel and Inspection Outage."

"U2 HPCI torus suction valve MO-2-23-058 failed to fully open, during performance of ST-O-023-301-2 'HPCI Pump, Valve, Flow, and Unit Cooler Functional and In-Service Test.' The valve stopped in a mid-position. HPCI flow path from Condensate Storage Tank remains available for HPCI injection. Investigation into cause is continuing."
