1. HS-1042B (HS-1043B), PZR to Quench Tank T-73 in CLOSE position.

HS-1042B (HS-1043B) checked in CLOSE position.

S U Comment:

RO, SRO-U SYSTEM c PALISADES NUCLEAR PLANT Page 5 of 13 JULY 2008 Proc. Step TASK ELEMENT 4 STANDARD Grade 2.0a.2 ENSURE the following conditions:

2. MO-1042A (MO-1043A), Power Relief Valve Isolation closed.

MO-1042A (MO-1043A) checked closed.

S U Comment:

Proc. Step TASK ELEMENT 5 STANDARD Grade 2.0a.3 ENSURE the following conditions:

3. PCS pressure control established:

SOP-1 2010 to 2100 psia PCS pressure checked between 2010 and 2100 psia S U Comment:

Proc. Step TASK ELEMENT 6 STANDARD Grade 2.0b PLACE HS-1042B (HS-1043B), PZR Quench Tank T-73 to OPEN for approximately 15 seconds, AND THEN PLACE to CLOSE, leaving handswitch in CLOSE position when complete.

HS-1042B (HS-1043B) placed to OPEN for approx. 15 seconds AND THEN HS-1042B (HS-1043B) placed to CLOSE, with handswitch left in CLOSE position.

S U Comment:

NOTE: Operator can do either channel first. Typically the left side valve operations (non-parentheses) are completed first.

CRITICAL STEP

RO, SRO-U SYSTEM c PALISADES NUCLEAR PLANT Page 6 of 13 JULY 2008 Proc. Step TASK ELEMENT 7 STANDARD Grade 2.0c OPERATE HS-1042A (HS-1043A), Power Relief Valve Isolation intermittently to the OPEN position until either of the following conditions is observed:

1. MO-1042A (MO-1043A) red position indication lamp lights (indicates valve is 5% open, green position indication lamp is also lighted at this point).
2. PRV-1042B (PRV-1043B), Power Operated Relief opens AND then reseats, THEN repeat Step 2.0c.

HS-1042A (HS-1043A) operated intermittently until red light lights.

S U 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.

CRITICAL STEP Proc. Step TASK ELEMENT 8 STANDARD Grade 1.0a.1 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:

1. CLOSE affected PORV Isolation Valve.

MO-1042A (MO-1043A), PORV Isolation Valve closed.

S U 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.

CRITICAL STEP

RO, SRO-U SYSTEM c PALISADES NUCLEAR PLANT Page 7 of 13 JULY 2008 Proc. Step TASK ELEMENT 9 STANDARD Grade n/a The following alarms annunciate with PORV opening:

1. EK-1373, SV AND/OR PORV OPEN, (Audible Acoustic Monitor alarm on back of Panel C-11A in alarm from FI-1042B Accelerometer (#4) Hi noise).
2. EK0743, Pressurizer PWR Operated Relief Valve Discharge HI Temp (TIA-0106, Relief and Safety Valve Discharge Temp, reads up-scale).

Following alarms are acknowledged:

1. EK-1373, Operator Action: Refer to ONP-18: Follow Up Action: Check Acoustic Monitor Panel for open valve; Check TIA-0106 discharge temperature; Refer to ONP-23.1.
2. EK-0743, Operator Action: Refer to ONP-23.1; Follow Up Action: Evaluate desired position of MO-1042A; Refer to LCOs; Refer to ORM.
3. Acoustic Monitor Reset pushbutton pushed to silence audible Acoustic Monitor alarm (PORV MOV Block Valve must be closed, for alarm to clear).

S U 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).

Proc. Step TASK ELEMENT 10 STANDARD Grade 1.0a.2 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:

2. RESTORE PCS pressure as directed by CRS.

PCS pressure restored to band as directed by CRS.

S U Comment:

Evaluator Cue: GIVE PCS pressure band of 2010 to 2100 psia, if asked by operator.

CRITICAL STEP

RO, SRO-U SYSTEM c PALISADES NUCLEAR PLANT Page 8 of 13 JULY 2008 Proc. Step TASK ELEMENT 11 STANDARD Grade 1.0a.3 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:

3. When directed by CRS, repeat Section 2.0 to open PORV Isolation Valve one additional time..

Since PORV still indicates open, the operator will NOT perform this step.

S U 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.

Proc. Step TASK ELEMENT 12 STANDARD Grade 2.0a.1 ENSURE the following conditions:

1. (HS-1042B) HS-1043B, PZR to Quench Tank T-73 in CLOSE position.
