Initial Conditions/Turnover:
When the crew assumes the shift reactor power is approximately 80% following a sequence exchange. On the last shift, repairs were made to the B FRV due to internal fault that caused the B FRV to lock. Once the crew takes the shift they will be required to reset the B FRV lockup using ARP 1C05A (F-1) section 4.
Following a sequence exchange, RE will request the crew to raise Reactor Power by 5% and hold prior to continuing raising power to 100%.

Initial Conditions/Turnover:
When the crew assumes the shift reactor power is approximately 100%. The B RHR Pump is inoperable due to breaker refurbishment; return time is approximately three days. After crew turnover, maintenance has requested immediately securing the B CRD Pump for a GE Service Bulletin that directs replacing the oil in the gear box.
