____________________________ (BOP)________________________
Initial Conditions: Reactor Power is at 81% and 100% rod line. Torus cooling is running with 1D RHR pump and 1B and 1C RHRSW pumps running to the 1B RHR Heat exchanger. APRM 2 is Inoperable and bypassed due to a failed power supply. Maintenance repair is complete. IMDI&C is presently reviewing closeout paperwork.
Outboard Drywell Isolation Spray Valve, MO1-1001-23A, is OOS because the motor tripped on overcurrent during valve testing. Inboard Drywell Isolation Spray Valve, MO1-1001-26A, is closed as per TS LCO 3.6.1.3, Condition A. Because Drywell Spray Subsystem A is Inoperable, TRM 3.6.a, Condition A, has been entered.
