Dresden NRC Dynamic Scenario Comments Scenario/Event COMMENT(S)
Resolution 1/2 Add role play note for QNE to verify rod control line if necessary to drop power after loss of condenser vacuum.
Done.
1 / 1 More detail for steps out of DOA 0300-06 and DOA 0300-12 Done.
1/3 Page 13, where it says may enter DGA-16 put in info that CR ventilation is to be isolated.
Done.
2/4&5 Page 13. SRO - Why isnt inhibiting ADS a critical task?
Licensee agreed that it should be a critical task. Done.
2/4&5 Page 11. Is the text about removing scram jumpers deleted or not? (It appears to be faintly lined out)
Yes it was removed.
2/4&5 Page 14. Add note that there is a conversion process for Rx Water Level above 500 psig.
Done.
3 / 2 Add additional TS items - Enter 3.6.2.1.a if Torus Temp is greater than 95 degrees and may enter 3.3.4.3.a for ERV instrumentation.
Done.
3/2 Move step to restart RB ventilation to after the reactor scram and the group 2 islolation.
Done.
Dresden NRC JPM Comments JPM Issue Resolution SRO Admin 1 OP-AA-105-102 provided is the wrong revision. Rev 5 was provided Rev 7 was in the simulator.
Licensee upgraded JPM with updated revision.
SRO Admin 2 Why arent steps 1& 3 critical steps?
Licensee agreed and made them critical steps.
SRO Admin 2 Step 3 requires more detail than perform DOA 0010-18, step D.4 After discussion with the licensee agreed to change to identify that steps of DOA 0010-18 step D.4 need to be performed. Done.
SRO Admin 2 Is DOA 0010-18, step D.4 really the correct action to take base on the information given in the JPM.
Changed the cue to read armed intruders were sighted within the protected area which removed any gray area.
SRO Admin 2 Why no steps for performing SY-AA-101-132, Step 4.5?
SY-AA-101-132 is a security procedure and should be performed by security not operations.
SRO Admin 3 DISCAM pages 1-5 would normally be filled out for the SRO review and it was not.
Put surveillance cover sheet on procedure Filled out the DISCAM in the JPM.
Done.
SRO Admin 4 None.
SRO Admin 5 Why isnt marking the correct classification level on the notification form a critical step (step 8)
Licensee made marking the correct classification level on the notification form a critical step.
Simulator a Tie step 3 to the cue so they dont end up on separate pages.
Put in the cue for step 3 that when the examinee attempts to print out the screen IF an error message is received then provide the pre-printed position sheet provided.
Put a note before step 3 that examinee may reference DOP 9950-03.
Add to step 14 to initial checklist 1.
Done.
Done.
Done.
Done.
Simulator b Steps 2,3,4, and 5 of JPM are what steps in what procedure.
Done.
Simulator d None.
Simulator e Cue in steps 1 and 6 that if examinee is confused that voltages are slightly off cue the examinee that voltages are equal.
Voltmeters dont always have good contact.
Done.
Voltmeters repaired and panel restored.
Simulator c Change initial cue to initiate isolation condenser to maximum flow and establish make up flow.
Done.
Simulator f Initial conditions should say that Rad/Chem has already been notified.
Initial conditions should say that system restorations from Group two are in progress.
Put in step 1 that there are 5 lights.
Step 13 REV is reverse.
Between 19 and 20 add Detector Position has digits.
First Note in JPM lists the wrong procedure to give to the candidate.
Done.
Done.
Done.
Done.
Done.
Done.
Simulator g Drop cue after step 11.
Cumulative run time in surveillance was not signed off as complete.
During the examination the simulator gave an unexpected response. The candidate was expected to start the A train of SBGT after receiving the Group II isolation signal. Upon doing this the A train heater started to cycle on and off and flow was fluctuating significantly.
This put the candidate outside the procedures. The candidate successfully completed this JPM but because the licensee could not get the simulator to respond as expected within a reasonable period of time this JPM was changed. The New JPM met the criteria and was validated by the licensee and the Chief Examiner before proceeding with the examination. The New JPM only required the start of the SBGT system.
Changed to read that if examinee starts to address alarms on 902-5 panel tell him that another operator will address the alarms. Done.
SAT Done.
Done.
In plant JPM I Change suspected seal leakage in initial conditions to seal leakage.
Done.
In plant JPM k None.
In plant JPM j None.
