Examiner Note: Crew may implement RNO at this time to isolate letdown; Crew may return to perform RNO for Trip Rx and initiate SI later when Leak increases.
Examiner Note: Since this is a MONITOR step, the crew may continue in the procedure while developing a Pzr/RCS level trend. If so, steps 3, 4 or 5 could be the decision point and therefore initiate the reactor trip and E-0 implementation. If a loss of Pzr level is imminent, the crew may decide to trip the reactor and transition to E-0 based on this step.
