RO, SRO-U SYSTEM c Proc. Step TASK ELEMENT 7 STANDARD Grade OPERATE HS-1042A (HS-1043A), Power Relief Valve Isolation intermittently to the OPEN position until either of the following conditions is observed: HS-1042A (HS-1043A) operated intermittently until red light lights.
- 1. MO-1042A (MO-1043A) red position indication lamp lights (indicates valve is 2.0c 5% open, green position indication lamp is S U also lighted at this point).
- 2. PRV-1042B (PRV-1043B), Power Operated Relief opens AND then reseats, THEN repeat Step 2.0c.
Comment:
NOTE: 5 seconds after MO-1042A (MO-1043A) has a red light, associated PORV will open and stay open. This will require the block valve to be closed.

- 1. CLOSE affected PORV Isolation Valve.
Comment:
NOTE: 5 seconds after MO-1042A (MO-1043A) has a red light, associated PORV will open, necessitating closing its block valve that was opened.
Evaluator: Operator action by procedure states that if 1800 psia is exceeded, affected PORV Isolation Valve must be closed. Operator should close valve before this pressure is reached.

Comment:
NOTE: Alarms do not affect this JPM. PORV MOV Block valve must be closed by procedure.
Operator should acknowledge and consult ARPs.
Evaluator Cue: If Operator begins to reference ONPs, STATE: Follow in-use SOP, ONPs will be referenced/entered if PCS leakage or loss of PZR pressure control remain evident.
Evaluator Cue: If Operator begins to reference LCOs, STATE: Another Operator will reference Technical Specifications and the ORM (Operating Requirements Manual).

Step TASK ELEMENT 11 STANDARD Grade IF a PORV opens during performance of Step 2.0c AND the applicable PCS pressure action limit is exceeded (SOP-1, 1800 psia), THEN the following actions shall be taken: Since PORV still indicates open, the operator 1.0a.3 S U will NOT perform this step.
Comment:
Evaluator Cue: If asked direction concerning repeating the steps with the PORV, direct them to perform the other PORV.
NOTE: The same sequence as above will be repeated, with the parentheses swapped for the other channel. The following operation will not cause a PORV opening.
