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:
- Loss of off-site power has occurred.
- Reactor has been tripped and all rods have been inserted into the core.
- Bus 1C has not been energized from 1-1 Diesel Generator.
- Electricians have determined that the 1-1 Diesel Generator governor has malfunctioned causing 1-1 Diesel Generator to trip.
INITIATING CUES:
- During performance of ONP-20, the Control Room Supervisor directs you to locally start and load 1-1 Diesel Generator per Step 4.7.2, "Manual Unit Control (EGA Malfunctioning)".

CRITICAL STEP Proc. Step TASK ELEMENT 5 STANDARD Grade 4.7.2c.1 IF the affected D/G is NOT running, THEN START affected D/G as follows:
- 1. PLACE Engine Control Switch on Local Gauge Board to Start position Engine Control Switch on Local Gauge Board placed to START S U Comment:
NOTE: Operator is not to insert the handle into the Local Gauge Board, simulate only.
NOTE: Handle must be inserted into Engine Control Switch, not in procedure.
NOTE: The 1-1 diesel engine is not running.
NOTE: EVALUATOR CUE: After the Operator simulates placing the engine control switch to START, CUE that the 1-1 diesel engine is not running.
JPM: RO, SRO-U SYSTEM j PALISADES NUCLEAR PLANT Page 6 of 10 JULY 2008 Proc. Step TASK ELEMENT 6 STANDARD Grade 4.7.2c.2 IF the affected D/G is NOT running, THEN START affected D/G as follows:
- 2. REMOVE handle from Engine Control Switch Handle removed from Engine Control Switch S U Comment:
NOTE: EVALUATOR CUE: After the Operator simulates placing the engine control switch to START, CUE that the 1-1 diesel engine is not running.
Proc. Step TASK ELEMENT 7 STANDARD Grade 4.7.2c.3 IF D/G did NOT start after performing Step 1, THEN PRESS AND HOLD for at least five seconds the Air Start Motor Solenoid Override pushbutton.
Air Start Motor Solenoid Override pushbutton pressed and held for at least five seconds S U Comment:
NOTE: Operator is not to press and hold the pushbutton, simulate only.
NOTE: EVALUATOR CUE: After the Operator simulates pressing and holding the Air Start Motor solenoid Override pushbutton, CUE: the 1-1 diesel engine is running NOTE: EVALUATOR CUE: Operator may verify proper operation of D/G, CUE: D/G is operating as expected (frequency, voltage, temps, etc)
CRITICAL STEP Proc. Step TASK ELEMENT 8 STANDARD Grade 4.7.2c.4 IF D/G did NOT start, THEN GO TO Section 4.5 Operator determines this step does not apply S U Comment:
JPM: RO, SRO-U SYSTEM j PALISADES NUCLEAR PLANT Page 7 of 10 JULY 2008 Proc. Step TASK ELEMENT 9 STANDARD Grade 4.7.2d.1 Utilize ladder from D/G Room to PERFORM the following actions as concurrently possible:
