NRC: Concur, scenario is satisfactory as written.

Scenario 2 1. The same PZR pressure channel failure occurs Lic: None of the crews will see both 1401S & 1402S, (1402S) here as in 1401S, albeit HIGH versus LOW. so there will not be any overlap between applicants.

There is overlap on TS (LCO 3.3.1). Choose NRC: Concur, scenario is satisfactory as written.
