Key Decision Point:
Step 1.2.b.3 is the discriminating step — the applicant must select the correct unit (Salem 2) ERDS Link Control and Status Display Screen, since the initial conditions state Unit 2 experienced the manual trip and RCS leak. Selecting Salem 1 would be an incorrect action. This same discriminating step appears in the 2020 and 2023 ERDS activation JPMs.
