Description:
Overview Initial Conditions:
The plant is currently operating at 89% power at MOC following a power reduction for replacement of the #3 LPSV Unitized Actuator. B CRD Pump is out of service for pump rebuild. Expected return to service is 4 days. Center SAC is NON-PREFFERED USE due to oil leaks on the compressor. Plans for the crew are to shift GSW pumps to run #6 GSW and shutdown #2 GSW to repair leaks on the discharge strainer. The crew is to then raise power with flow to 92%, then raise power at 3% per hour to 95%, and then hold at 95% to validate power vs steam flow per GOP 22.000.03.

Overview Initial Conditions:
The plant is currently operating at 89% power at MOC following a power reduction for replacement of the #3 LPSV Unitized Actuator. B CRD Pump is out of service for pump rebuild. Expected return to service is 4 days. Center SAC is NON-PREFFERED USE due to oil leaks on the compressor. Plans for the crew are to shift GSW pumps to run #6 GSW and shutdown #2 GSW to repair leaks on the discharge strainer. The crew is to then raise power with flow to 92%, then raise power at 3% per hour to 95%, and then hold at 95% to validate power vs steam flow per GOP 22.000.03.
NOTE: The crews Pre-job Briefing for the reactor power increase is to be conducted prior to entering the simulator. (Suggested time 30 minutes prior to beginning the scenario.)

Overview Initial Conditions:
The plant is currently operating at ~55% power during a plant startup (GOP 22.000.03, step 4.2.14). GSW Pump #6 is out of service for motor replacement. Expected return to service is 4 days. Plans for the crew are to raise reactor power to 60%, and place the second Reactor Feed Pump (RFP) in service. The Maneuvering Plan has been reviewed and approved by the SM.
NOTE: The crews Pre-job Briefing for the reactor power increase is to be conducted prior to entering the simulator. (Suggested time 30 minutes prior to beginning the scenario.)
The objectives of this scenario are to:
- 1. Recognize, respond to, and take the required actions for instrument/equipment failures requiring the use of operator and Tech Spec actions.
- 2. Direct and supervise the Shift team during Normal, Abnormal, and Emergency operations.
- 3. Recognize and respond to Seismic Events.
