CLINTON POWER STATION SYSTEM JPM JPM NUMBER: 4411.0801 REVISION: 02 READ TO THE OPERATOR I will explain the initial conditions, which step(s) to simulate or discuss, and provide the initiating cues.

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

SIMULATOR SET-UP CONDITIONS:

None TASK STANDARDS:

Control Rod 32-13 is fully inserted.

TOOLS, EQUIPMENT, OTHER SPECIAL REQUIREMENTS:

1. Tools are located in OSC. It is not required to take them to the containment.
2. CRDH vent valve wrench.
3. HP Hose with fitting.
4. Other wrenches in the kit.

CPS 4411.08, ALTERNATE CONTROL ROD INSERTION EVALUATOR INSTRUCTIONS:

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.
