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.
JPM: RO, SRO-U SYSTEM b PALISADES NUCLEAR PLANT Page 4 of 8 JULY 2008 Proc. Step TASK ELEMENT 1 STANDARD Grade n/a Locate EOP-4.0, Step 13 EOP-4.0 Step 13 located.
S U Comment:
Proc. Step TASK ELEMENT 2 STANDARD Grade EOP-4.0, 13.a IF ANY of the following conditions exit:
Containment pressure is greater than or equal to 4.0 psig Any operable Containment Radiation Monitor rises to 1 X 101 R/hr, THEN PERFORM ALL of the following:
- a. VERIFY CIS INITIATED (EK-1126) is alarmed CIS INITIATED (EK-1126) has not alarmed.
Either HIGH RADIATION INITIATE pushbuttons on Panel EC-13 pushed:
CHRL-CS CHRR-CS S U 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 EOP-4.0, 13.b IF ANY of the following conditions exit:
Containment pressure is greater than or equal to 4.0 psig Any operable Containment Radiation Monitor rises to 1 X 101 R/hr, THEN PERFORM ALL of the following:
S U Comment:
JPM: RO, SRO-U SYSTEM b PALISADES NUCLEAR PLANT Page 5 of 8 JULY 2008 Proc. Step TASK ELEMENT 4 STANDARD Grade Supp.6, 1.0 ENSURE CLOSED all valves unless otherwise specified by the notes.
Verifies that all valves closed as required, checking them off on the checklist, except for the CWRT Vent Valves, CV-1064 and CV-1065.
S U 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 Supp.6, 1.0 ENSURE CLOSED all valves unless otherwise specified by the notes.
CWRT Vent Valves, CV-1064 and CV-1065 have failed to isolate, Handswitches for both CV-1064 and CV-1065 are placed to close.
CV-1064 is verified closed (green light on), CV-1065 remains open (red light on)
S U 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.
CRITICAL STEP
JPM: RO, SRO-U SYSTEM b PALISADES NUCLEAR PLANT Page 6 of 8 JULY 2008 Proc. Step TASK ELEMENT 6 STANDARD Grade n/a Report status of EOP Supplement 6 for Containment Isolation to the CRS.
CRS informed of completion of EOP Supplement 6 and all containment isolation valves are closed, with the exception of CV-1065.
