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.

11. When JPM is revalidated, SME or Instructor sign and date JPM cover page.

Amplifying cues are provided within the JPM steps.

INITIAL CONDITIONS AND INITIATING CUE:

A reactor scram occurred but control rod 32-13 failed to insert. Individually scram control rod 32-13 by venting the CRDH withdrawal line in accordance with CPS No. 4411.08, ALTERNATE CONTROL ROD INSERTION. The containment is accessible, the reactor is shutdown and you have RP support.

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

• 1.

Connect a hose from selected HCUs 1C11-1F102, CRD Withdraw Riser Vent Valve to below the Suppression Pool water level. (Valves located in HCU cat walk area)

Standard Examinee simulates removing the plug from the CRD riser vent valve.

Examinee should verify 1F102 shut before removing the plug.

CUE Comments The HCU for control rod 32-13 is located at 755' Containment Building, east side, on the outboard end of the second bank of HCU's near the stairway from 737' to 755'. If desired the evaluator may select a different HCU if access to 32-13 is limited. Examinee should explain the venting hose assembly process and routing of the hose. (Access to the vent valve is a catwalk.)

SAT UNSAT Comment Number

• 2.

Shut 1C11-F102, HCU Withdraw Riser Valve. (First valve on right above HCU)

Standard Examinee simulates closing the valve for control rod 32-13.
