JPM: RO, SRO-U SYSTEM b EXAMINER COPY ONLY Tools/Equipment/Procedures Needed:
EOP Supplement 6, Checksheet for Containment Isolation and CCW Restoration, Rev. 7 Also see Simulator Operator Instructions (last page of this document).
READ TO CANDIDATE DIRECTION TO CANDIDATE:
I will explain the initial conditions, and state the task to be performed. All control room steps shall be performed for this JPM, including any required communications. I will provide initiating cues and reports on other actions when directed by you. Ensure you indicate to me when you understand your assigned task. To indicate that you have completed your assigned task return the handout sheet I provided you.
INITIAL CONDITIONS:
- A Loss of Coolant Accident has occurred.
- The Reactor has been tripped and EOP 1.0, "Standard Post Trip Actions" have been performed.
- Containment radiation is above 10 R/hr.
- Automatic Containment isolation has not occurred.
INITIATING CUES:
- During performance of EOP 4.0, "Loss of Coolant Accident Recovery", the Control Room Supervisor directs you to manually initiate Containment isolation, referring to Step 13.

Proc. Step TASK ELEMENT 2 STANDARD Grade IF ANY of the following conditions exit:
Containment pressure is greater CIS INITIATED (EK-1126) has not alarmed.
than or equal to 4.0 psig Either HIGH RADIATION INITIATE pushbuttons Any operable Containment Radiation 1 on Panel EC-13 pushed:
EOP- Monitor rises to 1 X 10 R/hr, S U 4.0, 13.a THEN PERFORM ALL of the CHRL-CS following:
CHRR-CS
- a. VERIFY CIS INITIATED (EK-1126) is alarmed Comment:
NOTE: Operator verifies CIS INITIATED (EK-1126) is in alarm once pushbutton is pushed, it is permissible, but not necessary, to push both pushbuttons.
CRITICAL STEP Proc. Step TASK ELEMENT 3 STANDARD Grade IF ANY of the following conditions exit:
Containment pressure is greater than or equal to 4.0 psig EOP Supplement 6 obtained.
Any operable Containment Radiation 1
EOP- Monitor rises to 1 X 10 R/hr, THEN PERFORM ALL of the S U 4.0, 13.b following:
- b. VERIFY Containment Isolation, Refer to EOP Supplement 6 Comment:
PALISADES NUCLEAR PLANT Page 4 of 8 JULY 2008
JPM: RO, SRO-U SYSTEM b Proc. Step TASK ELEMENT 4 STANDARD Grade Verifies that all valves closed as required, ENSURE CLOSED all valves unless Supp.6, checking them off on the checklist, except for otherwise specified by the notes. S U 1.0 the CWRT Vent Valves, CV-1064 and CV-1065.
Comment:
NOTE: Determining that the CWRT Vent Valves failed to close is the only action needed to satisfactorily perform this critical step.
Evaluator Que: If asked by the operator what should be done with CV-1064 and CV-1065, RESPONSE: direct operator to perform EOP Supplement 6.
CRITICAL STEP Proc. Step TASK ELEMENT 5 STANDARD Grade CWRT Vent Valves, CV-1064 and CV-1065 have failed to isolate, ENSURE CLOSED all valves unless
- Handswitches for both CV-1064 and otherwise specified by the notes. CV-1065 are placed to close.
Supp.6, S U 1.0
- CV-1064 is verified closed (green light on), CV-1065 remains open (red light on)
Comment:
NOTE: CV-1064 closes, CV-1065 remains open.
NOTE: Placing the handswitch for CV-1064 to close is the critical component of this step.
