JOB PERFORMANCE MEASURE VALIDATION CHECKLIST NOTE: All steps of this checklist should be performed upon initial validation.

Prior to JPM usage, revalidate JPM using steps 8 through 11 below.

________ 1. Task description and number, JPM description and number are identified.

________ 2. Knowledge and Abilities (K/A) references are included.

________ 3. Performance location specified. (in-plant, control room, or simulator)

________ 4. Initial setup conditions are identified.

________ 5. Initiating and terminating cues are properly identified.

________ 6. Task standards identified and verified by SME review.

________ 7. Critical steps meet the criteria for critical steps and are identified with an asterisk (*).

________ 8. Verify the procedure referenced by this JPM matches the most current revision of that procedure:

Procedure Rev. _____ Date _____________

________ 9. Pilot test the JPM:

a. verify cues both verbal and visual are free of conflict, and

b. ensure performance time is accurate.

________ 10. If the JPM cannot be performed as written with proper responses, then revise the JPM.

When you complete the task successfully, the objective of this Job Performance Measure will be satisfied.

SIMULATOR SET-UP CONDITIONS:

Reset to a shutdown IC, at ~300 psig with a vacuum pump, CW in operation and Main Turbine reset, then:

1) Close the Inboard MSIVs

4) Depressurize equalizing header with BPV jack to ~50 psig

5) Set pressure set at >315 psig TASK STANDARDS:

Operator actions performed per CPS No. 4411.09 TOOLS, EQUIPMENT, OTHER SPECIAL REQUIREMENTS:

CPS No. 4411.09 RPV PRESSURE CONTROL SOURCES EVALUATOR INSTRUCTIONS:

Amplifying cues are provided within the JPM steps.

INITIAL CONDITIONS AND INITIATING CUE:

A loss of IA resulted in closure of the Inbd. MSIVs. IA has been recovered. EOP-1 has been entered and to assist in RPV pressure control you are directed to reopen the Inbd. MSIVs per CPS No. 4411.09.

PERFORMANCE INFORMATION Critical steps are denoted with an asterisk (*) to the left of the step number and appear in BOLDED letters. Failure to meet the standards for a critical step constitutes failure of the Job Performance Measure. The sequence of steps is assumed unless denoted in the comments section of the JPM.

==============================================================

PERFORMANCE STEPS 2.2.1 MAIN STEAM - CONDENSER/BYPASS VALVES/MSL DRAINS

1. IF This section was entered from EOP-2, EOP-3 or SAG-2, THEN 1) OK to defeat isolations per CPS 4410.00C007, Defeating RPV Vent Interlocks.

2) OK to exceed 100°F/hr cooldown.

2. Reset any cleared GROUP 1 isolations.

Standard Determines that no pressure control system interlocks need to be defeated and that Group 1 isolation is reset.

3. Regardless if Circ Water (CW) is available or not:

1) Establish vacuum per CPS 3112.01, Condenser Vacuum (CA), or

2) If vacuum cannot be established, open 1CA007, Condenser Vacuum Breaker Valve.

Standard Determines that Condenser vacuum is already established.
