READ TO OPERATOR DIRECTION TO TRAINEE:
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 SGTR has occurred coincident with a loss of offsite power and 2ERPO. The CRS has EP/21A15000/E-3 (Steam Generator Tube Rupture). Step 19 is currently in effect implemented EP/2/A/5000/E-3 to cooldown the NCS.
INITIATING CUES:
The CRS directs you to fully open 2SV-1 (S/G 20 PORV) locally per EP/21A15000/E-3 EP/2/A/5000/E-3 Enclosure 3 (Local Operation of S/G PORVs).
This JPM is time critical.

STARTTIME:
START TIME: _ __
EXAMINER NOTE:
In the analysis for this event, it has been determined that a maximum of 18 minutes is allowed from the time the NLO is given the procedure in the control room, to the time the valve is fully open. Since 10 minutes were allotted to get to the valve, and 2 minutes are allotted to expose the shaft for manual engagement, the trainee must have 6 minutes left to fully open the valve once the clevis is engaged, and he has demonstrated the proper direction to turn the handwheel to open the valve.
Critical Time starts when the student states he/she is ready to proceed.
