SUMMARY
OF UNIT 1 OPERATING EXPERIENCE March 1986 3/1 Unit One began this reporting period at 100% Reactor Power (860 MWe).
3/3 At 0945, reduced power (725 MWe) to investigate loss of #14 Circulating Water Pump (#14 CWPP). The associated sump pump did not operate and siphon clogged.
3/3 At 1830, Unit returned to full power (860 MWe), troubleshooting of phase "A" inconclusive.
3/17 At 1945, the Unit began power decrease for mini-outage repairs to the Reactor Coolant System Code Safety Valves (1-RV-200,201), PORV, #11B Reactor Coolant Pump Seal and other appropriate maintenance items.
3/18 At 0223, the Unit was removed from the grid.
3/24 At 0633, the Reactor was critical (Mode 2) for Plant startup. At 1005, the reactor was in Mode 1. At 1422, the Unit was paralleled to the grid and beg m a normal ramp up to full power.
3/24 At 2300, (#14 CWPP was removed from service when it tripped) Unit I
stabilized at 760 MWe.
3/27 At 0629,14 CWPP was re-installed and operating Unit began increasing to f uit load. At 1030, the U.11t was at full power (860 MWe).
3/31 The Unit was at full power (860 MWe) at the end of this reporting period.
SUMMARY
OF UNIT 2 OPERATING EXPERIENCE March 1986 3/1 The Unit began this reporting period at full power, reactor at 100% (860 MWe).
3/14 The Unit began decreasing power @ 2155 for a balance shot repair of #3 and
- 6 Main Turbine bearings (associated with LP "B" Turbine) and other applicable maintenance.
3/15 At 0145, the Unit wat removed from the grid and entered Mode 2. At 0230, the Reactor entered Mode 3.
3/16 At 0250, the Reactor was critical (Mode 2) for Plant startup. At 0400, the Reactor entered Mode 1 and the Unit was paralleled at 0450. Normal return to power was limited by plant water chemistry holds but at 2000, the Unit was returned to full power (860 MWe).
3/29 At 0230, reduced power to 96% (820 MWe) to repair 21 Heater Drain Tank Normal Level Control Valve Stem (which snapped). At 1342 began increasing power. At 1500 returned to full power (860 MWe).
3/31 At the end of this reporting period, the Unit was at 100% power (860 MWe).
