NRC COMMENTS TO THE OPERATING TEST AND WRITTEN EXAMINATION (ES-401-9) FOR THE POINT BEACH INITIAL EXAMINATION - NOVEMBER 2005 Comments on Point Beach JPM's JPM P015.005A: Admin JPM (Both) Step 1 : Have candidate determine reactor power, don't spoon feed him. RE: delete reference to power in Cue. Steps 2, 3, &4: Delete, "if administering in simulator" since JPM will be administered in simulator.
RE: will delete references to simulator.
Step 10: Why is there a range of correct power reduction?
RE: Due to error/tolerances from reading gages.
24 - 30 % calculated power acceptable range.
JPM POO1.001: Admin JPM (both)
Steps 3, 4, & 5: Evaluator note contradicts with examiner cue!!! Equipment in these steps will be manipulated! RE: Will add "unless authorized to evaluator note.
Step 3: Blender Operations.
Need to establish an acceptable range of water and/or acid settings.
RE: will include acceptable range. JPM P015.004: Admin JPM (both) NOTE: During onsite validation, examiners identified a faulty Operator Select switch on N31. Needs to be repaired prior to exam day. RE: Simulator staff will repair switch or exercise as necessary to guarantee correct operation.
JPM P088.008: Admin JPM (RO) N0TE:Why is it necessary to say wind direction is from the North, (towards Two Creeks)??
RE: Will delete "towards Two Creeks." JPM POOO.011: Admin JPM (SRO) Gaseous Waste Discharge Permit attached to JPM has lineout of 1.35E-05 and replaced with "yesterday." Appears to be an incorrect lineout! RE: No, this is a known longstanding chemistry workaround since they have been having problems with their computer output. lssue has been provided to RP inspectors for review. Licensee documented this issue on CR. JPM P028.001a: Admin JPM (SRO) Licensee questioned the supporting regulations behind 15 minutes to classify and 15 minutes to notify. RE: 15 minutes to classify the event is rooted in regulations via NUREG 99-02, Performance indicators.
15 minutes to notify is rooted in regulations via NUREG 0654 and the licensee's EP plan which is specified in the operating license. Will change cover sheet to reflect time critical evolution. Will change cue sheets to add, 'This JPM is time critical."
JPM POOl.020: Simulator JPM None JPM P004.013:
Simulator JPM Step 4: Why isn't this step critical?
You need cooling water to excess UD Hx. RE: Not a critical step since valve is already open!
Step 10: How is the RCDT level determined? Computer point, PAB A0 call? RE: PAB A0 will call CR with level reading. How much will PZR & VCT level drop due to this diversion?
RE: The level change is small - not an issue! Step 18: Charging flow allowed to continue?
Why not isolate? RE: Charging flow is dialed down to minimum. JPM PO10.010: Simulator JPM Step 10: Why not have 1 PT-420 failed high prior to placing RC-430 LTOP key to ON? This would tell if the operator really knows what he is doing or just following a procedure.
Discrimination.
RE: Good idea, but if operator sees failed PT, operator may not perform JPM. Step 11: How long will it take from the time the PORV opens until the
- I RCP seal DP Step 11: Need to add step from Conduct of Operations Manual that directs operator to take manual control when auto control fails. RE: Done Low Alarm annunciates (the failure criteria)?
RE: Timed at 55 seconds. JPM P000.028:
Step 6: If candidates performs steps 17 and 18 of CSP-H.1, these steps would be incorrect. The candidate should proceed to step 19 (correct) and not perform steps 17
& 18. However, in either case, the candidate will still perform step 19 of CSP-H.1. The difference is that RCS pressure would be unnecessarily reduced to 4765 psig had the candidate performed the incorrect steps.
Conclusion:
This would warrant a comment for procedure adherence/panel monitoring but since there is no adverse consequence, this would not be a criteria for failure. Step 19: Add evaluator due to open breaker for SGFP discharge valves when valves fully open.
RE: Done Step 20: No consideration as to whether SG is hot & dry prior to feed flow re-initiation.
Procedure doesn't even check it. Why? Has an evaluation been done that says it is not a problem to put cold water into a hotldry SG? RE: Yes, this has been evaluated per EOP Revision IC - OK to feed hot dry SG. Step 23: Not sure why this is a critical step?
If flow path is established and a pump is running and S/G is depressurized level will be stable or increasing. Action is met with no effort.
RE: This is why step 22 is not critical.
But need to have applicant complete step 23 to ensure JPM is completed.
JPM P026.002:
Step 4: Why open the valve first then start the CS pump? Isn't there a concern with during SI actuation.
Step 6: Is there a minimum NaOH flow rate? Should valve be full open?
RE: There is no minimum f/ow rate, valve is selected to full open. Flow rate is established by use af a preset throttle valve. water hammer conditions?
RE: This is the sequence used for automatic pump start JPM P062.013:
No comments.
JPM PO1 5.01 1 : Step 4 & 6: Step 4: Why is it that the gain pot can be adjusted even though if it is locked in position?
Sounds like a degraded condition in need of maintenance!
Attachment A: Why are N42, N43, & N44 marked MA? The Examinee should mark these N/A if he or she see fit. RE: JPM requires only that Nl channel N41 be aqusted! Is gain pot really on drawer "B?" RE: Yes JPM POOO.015: Cue Sheet:
Why is it necessary to give candidate procedure to use? Shouldn't they demonstrate that they know how to get procedure?
RE: Candidate should demonstrate to examiner that he knows where to locate procedures.
Must be done during an early JPM. Once demonstrated, need not be repeated. Step 7: We should not direct Examinee to NOT enter a procedure.
During a real situation he needs to be able to decide which procedure to be in. RE: Cue will reflect that another operator will perform Attachment A. In-Plant JPMS: JPM P000.036b:
Step 3: Delete asterisk from Critical attribute and state, "pump is found running."
Delete, "If pump found off ..." RE: Incorporated.
Step 8: Which way will 2CV-361A be throttled to obtain 47psig?
I assume open. RE: Correct! Added comment to step 8. JPM P000.039:
Step 16: Ensure candidate operates the governor control switch to change frequency and not the voltage regulator switch! Ensure candidate looks at proper indications!
RE: Will change cue sheet such that after EDG starts, that frequency will be at 61 hz. This will necessitate candidate to adjust frequency.
JPM P008.003: Cue Sheet:
Is it possible to observe a tube side through-wall leak? RE: No! Will change to a shell side leak.
Scenario Comments Scenario #I : Event #I: BOP should not receive credit as an instrument failure for this event since there is no diagnosis of the event. RE: Will change D-7 sheet to reflect that BOP will receive credit for Normal for tripping bistables.
Event #I, Page 3 of 5: Why have SRO turnover command and control? Why not let SRO remain in CR and have surrogate perform behind panel manipulations?
OR, if surrogate takes command/control, ensure no changes to plant conditions for time SRO is gone! RE: Will ensure no changes to plant for time SRO is gone. Surrogate will act for SRO during his short absence. Event #3: Does MFP temperature increase gradually or quickly. For example, if it increases slowly, will operators note increase in MFP bearing temperature during initial walkdown of simulator prior to taking watch?
RE: Slow ramp, won't be seen during initial setup/walkdown of simulator.
Event #3: We do not want the main feed pump to trip before the power reduction. This is necessary to ensure we get a reactivity change. RE: True! MFP won't trip. Event #4/5:
Page 5, Verify RCS temperature control. Temperature should be low due to feedwater line break. What actions are required for this step? RE: RCS temperature control is a continuous action step. Page 7: Scenario does not appear to go ;'oo far into the EOPs. Scenario is stopped prior to SI termination.
See if there is any value in continuing the scenario into EOP 1, Loss of Reactor or Secondary Coolant.
RE: Add EOP 7.7 steps up to step 72. We will evaluate into EOP 7.7. Scenario #2: Event #2: Which trip bistable(s) can be removed that would cause a Rx Trip? They should be specified in Applicants Action column on page 3 of 4! RE: SRO has already demonsfrated ability to remove control power fuses during previous scenario.
Can't remove bistables during this scenario since it will cause a reactor trip. SRO should not leave control room to pull fuses - will follow TS requirement to shutdown instead. Event #3: Do actions in AOP-24, "Response to Instrument Malfunctions," allow the BOP to place the FWRV back in AUTO? If not, then BOP will be 'attached' to the panel for the rest of the scenario (until the major). RE: The FWRV will not be placed back into AUTO. Operator will need to monitor SGWL until major event is put in - next step. Events #4, 5 , 6, 7: (Page 5 of 13): Is an auto trip of the RCP plausible? The crew should trip the affected RCP rather than the RCP auto trip. RE: During onsite validation, crew tripped RCP prior to auto trip. (Page 10 of 13): Evaluate continuing scenario until after cooldown/depressurization has been initiated per EOP 1.2. RE: Examiners will determine if enough crew has had enough material to be evaluated on.
Scenario #3 Event #2: I assume that the SRO will remain in the controls area for removing of fuses. RE: SRO will turnover watch to surrogate, exit CR to supervise evolution, then return.
No events will happen while SRO is outside CR. Event #3: Determine if the BOP operates any equipment during this event! The way this event is written, it sounds like the BOP could just watch and do nothing in response to this event. RE: BOP has to start standby fans in sequence.
Event #4: I don't believe there are sufficient actionslmanipulations for the RO and BOP to do during this event. I suggest that the EDG start and NOT load onto the bus. This will allow the BOP operator to perform an action - close the breaker. We will need to delete 'ALL' from the D-1 sheet and replace it with a
'BOP - C designator.
We will need to add an additional event for the RO to ensure we meet our bean count!
RE: BOP must realign pumps/valves for blender operations on the back panel. RO must reposition switch and aaust charging flow. Its minimal - but evaluatable!!
Event #5, D-1 sheet: Remove
'GO3 fails to start' and add to Event 4. Need to add some failure to Event #5. Perhaps containment isolation valves fail to close (see page 2 of 9). RE: Simulator scenario ran fine as written. Don't make this change. Event 5, 6, Page 9 of 9: Why is emergency boration a critical step? Don't you have to wait till cooldown?
RE: It is required to initiate boration due to two stuck rods prior to exiting EOP 0.1.
Scenario 4 This scenario does not have enough component/instrument failure events for the RO! This scenario does not have any TS calls for SRO - must ensure that all SRO beans for TS have been met prior to running this scenario on SRO candidates!
Event #2: The D-1 sheet has this event as a reactivity change for the RO position. Need to verify that the RO changes power during this event. Otherwise, need to put in reactivity change and change D-1 sheet. RE: We did not believe that the RO did anything in this position to warrant a credit for reactivity change.
If this spare scenario is used, we will need to add a bean for reactivity change. Similarly, the D-1 sheet has Event 2 as BOP action.
Need to verify BOP has actions for this event to ensure we meet our bean count! RE: BOP had some actions on the panels associated with main feedwater.
Events 3, 4, & 5, Page 4 of 12: Will 'A' SG FWP trip during performance of Attachment A? It shouldn't so they have to deal with a faulted SG and an overfeed condition.
RE: Both SGFWPs will be tripped /A W Attachment A of EOP-0. Events 3, 4, & 5, Page 6 of 12: Can't control RCS temperature if both SG's are faulted!
RE: True, there is a continuous action step to verify RCS temperature control. This is accomplished by restricting FW flow to SGs.
Events 3, 4, & 5, Page 7 of 12: Will MFP be tripped before step on top of pg 7? If not, will they be able to locally shut the FRV or Isolation valves? Is this possible with MFP running and generating such a high d/p? RE: Operators will be able to close the MFP discharge isolation valves with a high dp. Events 3, 4, & 5, Page 7 of 12: "Control Feed flow to minimize cooldown." Will there be a transition to FR-P.1 at this step?
If not, why not? RE: No, there will be no transition to FR-P. 1 due to the procedure sending you back to EOP-1, Loss of Secondary Coolant.

The question is not linked to the job requirements (i.e., the question has a valid WA but, as written, is not operational in content). The question requires the recall of knowledge that is tca specific for the closed reference test mode (i.e., it is not required to be known from memory). The question contains data with an unrealistic level of accuracy or inconsistent units (e.9.. panel meter in percent with question in gallons). The question requires reverse logic or application compared to the job requirements.
