Simulator Scenario Outline Comments (Date)

Comment Resolution Scenario #2, #3, and #4 contain actions Scenario # 1 and Scenario #3 were used on 1 of stopping an excess steam demand the Operating Exam. Scenario #2 was the and have very similar mitigation spare.The excess steam demand was only strategies. used on one simulator sceanario.

2 Heater Drain Pump trips were used on Scenario #2 became the spare scenario.

2017 and 2019 exams. The mitigation OBDI 202 - IOLE Process Rev 3 strategy of the proposed scenario #2 for the 2021 exam of lowering reactor power to 60% is different than the 95%

of 2017 and 2019. I want to look at this closer to be sure this event is different enough from 2017/2019. If we keep this event, could we shear a shaft or break the discharge line from the pump instead of reusing the trip?
