SUMMARY

The plant at 50% power. Power ascension was suspended to allow Electrical Maintenanceto perform an inspection of T4 following a report of a cooling fan problem. Busses 10200 and 10400 are currently fed from Reserve. Electrical Maintenance has successfully completed the inspection of T4. The shift will restore the electric plant lineup to normal by transferring busses 10200 and 10400 from Reserve to Normal.

Raise reactor power with control rods. Start at Step 46 with rod 30-19. Pull from notch 12 to 24.

Continue power ascension per OP-65.

SUMMARY

Drywell is being purged IAW OP-37 D.6.11. SBGT'A' is running to vent torus

'C'Condensate pump is running in preparation for securing 'B' condensate pump for maintenance Control rods are a t Step 47 Critical Task #2: Directs declaration of SAE due t o failure of RWCU t o isolate Critical Task #3: Open 7 ADS valves LO1 08-01 NRC LO1 Examination Scenario 5 Page 4 of 12

Ensure RPV water level stabilizes.

IF reactor water level control was placed in manual control, THEN restore reactor water level control to automatic when directed by the Shift Manager.

Restore RFP control to Auto per OP-2A G.41 Balance RX WTR LVL CNTRL 06LC-83 controller by adjusting SP ADJUST knob.

Place RX WTR LVL CNTRL 06LC-83 controller in BAL.
