CHANGES TO THE OPERATING EXAM SINCE THE INITIAL SUBMITTAL Control Room/In-Plant Systems u
JR012.008 Borate RCS for SDM Change :
Made Step 4 (Reset SI) Critical Reason:
Resetting SI necessary to complete the actions JR005.009 Establish S/G Cooling per AP-RHR. 1 Change:
Reason:
Steps 5 (Start RHR), 9 (RCS Closed), and 10 (Monitor RCS Temp) made critical Each is a required transition in the procedure JROlO.003 Depressurize RCS using N2 Change:
Reason:
Deselected Alternate Path on this JPM Test item did not provide sufficient discrimination when used as an alternate path i/
JR029.001 Startup the CNMT Mini Purge Change:
Reason:
Made step 3 not critical The step verifies an expected condition; no operator action needed JC063.001 Align TSC Battery to Main Fuse Cabinet 1B Change:
Steps 3 and 5 not critical Reason:
The steps verify normal conditions, no operator action needed JC 103.007 Attachment CI/CVI Change:
Reason:
Removed SOV-922 from list of valves to isolate All valves now in RCA; improves efficiency of JPM administration
RO Admin. Exam JROOl.008 Calculate SDM for an Operating Reactor with an Untrippable Rod Change:
Modified P M to allow its use in classroom without needing the plant or simulator b
Reason:
Improves efficiency of JPM administration J R O 1 5.OO 1 Manually Calculate QPTR Change:
Reason:
Modified JPM to allow its use in classroom without needing the plant or simulator Improves efficiency of JPM administration JR352.001 Monitor Critical Safety Function Status Trees Change:
Modified JPM to allow its use in classroom without needing the simulator and change critical step so that only abnormal conditions are critical Reason:
Improves JPM administration efficiency; normal (GREEN path) conditions not critical
SRO Admin. Exam JS343.003 Shift Staff Emergency Call-In Change:
Rewrote JPM to focus on overtime limits and to have explanation of reasons for rejection u
Reason:
Better discrimination JS341.001 Loss of Safety Function Determination Change:
Added more Out of Service Equipment Reason:
As written, the safety hction determination was too straight-forward and non-discriminatory; additional 00s equipment adds realism and requires more analysis
Simulator Scenarios Scenario 04-2 Changes:
- 1) Added "A" Charging Pump 00s at beginning of scenario
- 2) Moved Hotwell Level Failure to later in the scenario
./'
Reasons:
- 1) Given more actions for the operator to perform when offsite circuit is lost
- 2) If the operator fails to take action in time, to limit the effect on the scenario of the resulting Rx Trip Scenario 04-3 Changes:
- 1) Insert PT-429 Failure as an existing condition at the beginning of the scenario
- 2) Move Charging Pump Speed Failwe earlier in the scenario Reasons:
- 1) Required to cause an inadvertent SI later in the scenario but by itself does not
