Comments and Question Modification History LEGEND FOR INITIALS:
RJC = Rich Conte (NRC) PAP = Peter Presby (NRC) BCH = Brian Haagensen (NRC) DAP = Dan Pantalone (MS2) SRM = Steve Myers (MS2)
JMD = Joe D'Antonio (NRC) DEJ = Don Jackson (NRC) RJA = Duffy Ashey (MS2) RLC = Bob Cimmino (MS2)
- 1. (JMD 11/10/04) Okay, but fairly simple question.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (RJC 12/13/04) Licensee may argue RO level. Let it go, we will see.
- 4. (DAP 12/16/04) Recommend changing stem to "While performing 2601D "Safety Channel and Delta T Power Channel Calibration", the plant tripped. EOP 2525 "Standard Post Trip Actions' are complete. The STA has just completed the first Safety Function Status Check (SFSC) for EOP 2526 "Reactor Trip Recovery". All Safety Functions are satisfied.ll A short time after the SFSC, the plant becomes unstable.ll Based on the following information, identify the procedure that must be implemented." Distractors are okay. Change original parameters as follows: CRS to US, pzr press 2010 to 2100, SG pressures 880 to 810, 900 to 870, SG levels 68% in #1, 64% in #2, Tc 531 to 528, Th 533 to 532.
Reasons: #1 SG level is rising because the lower pressure pulls more FW into that SG. After a trip, the Feed Reg Vlvs are in manual so no auto level control.
Reasons for my suggested change. If we tripped on a steam leak , even though it was not large enough for the 2541 Appendix 1 "DIAGNOSTIC FLOW CHART", the crews would still go from 2525 to 2536. This is done because 2536 "ESD" is the best EOP to do a cooldown and isolate the SG. Also, if there were a bad steam leak upstream of the MSIVs that was not degrading the plant, as indicated by the SG Pressures 880 and 900, the crew would not trip and close the MSIVs. Doing so would not isolate the steam leak, but more important, the thermo/hydraulic shock may open up the pipe and cause a rupture. They would probably do a rapid downpower and be off line ASAP without tripping from 100%.
- 5. (DEJ 01/10/05) Are there any fire alarms in "East Pen Area"? May want to add EPA FIRE Alarm in alarm. Also, is room temp available in CR, should add that too with trend. Great question.
- 6. (PAP 01/11/05) Changed CRS to US. US could plausibly order MSIV closure in response to large unapproachable leak in penetration room. Removed "upstream of MSIV MS-64A which has filled the area with steam" to make US direction more reasonable. Will ask licensee about fire alarm for that room and remote temp indication.
- 7. (JMD 01/31/05) Reviewed changes. Ok.
- 8. (RLC 03/15/05) Recommend modifying the stem by deleting reference to a large steam leak and replacing with a trip from loss of the 'A' FP. This puts the crew into a clean trip that allows them to complete 2525 and transition into 2526. With the steam leak, the crew would have never transitioned to 2526, they would have gone directly to 2536 (ESD).
- 9. (PAP, JMD 03/16/05) Modified as recommended. Discussed with licensee.
- 1. (JMD 11/10/04) Consider adding to stem to indicate that all of the required actions up to the desired answer have been performed.
- 2. (PAP 12/07/04) Left as-is, pending feedback from licensee review.
- 3. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 4. (DAP 12/16/04) Add "Pressurizer level is 33% and rising" to stem. Change distractor B to "Isolate Letdown." The original distractor [Manually initiate SIAS] is a valid answer. The operators are trained to manually initiate SIAS early if conditions degrade to the point that PZR Pressure is less than 1850 psia on a trip and still lowering. EOP-2525 (step #3 contingency) directs the operator to manually operate charging and letdown if pressurizer level is not beign restored to the 35-70% band. Level is at 33% and rising.
- 5. (PAP 12/28/04) Changed as recommended.
- 6. (DEJ 01/10/05) Give some PRT parameters too that show PORV's not leaking. What indications are there of spray flow? Temps?
- 7. (PAP 01/11/05) PORV leaking would be indicated by acoustic monitors. Enough information provided to rule out PORVs. Question requires applicant to use provided information to determine that spray valve must be open/leaking.
Left question as is.
- 8. (JMD 01/31/05) Reviewed changes. Ok. No need for quench tank parameters, acoustic monitor given.

- 1. (JMD 11/10/04) Okay. Better if a more operational question.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (PAP 12/13/04) Identified as memory level.
- 4. (DAP 12/16/04) Okay.
- 5. (DEJ 01/10/05) Wow. Great question.
- 7. (RLC 03/15/05) New Accident Analysis performed for justification of removal of Charging Pumps from plant Technical Specifications verifies that on a SBLOCA the core is NOT uncovered. The question should be modified to allow for the K/A, however, distractor "B" can NOT state "core uncovery" is unique to a LBLOCA to be an incorrect response (Accident Analysis now states that it is). Recommend changing distractor B to "Only the LBLOCA requires heat removal from CTMT Spray."
- 8. (PAP, JMD 03/16/05) Modified Choice B as recommended. Discussed with licensee.
- 1. (JMD 11/10/04) Okay.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (PAP 12/13/04) Identified as memory level.
- 4. (DAP 12/22/04) While the above question is technically true, in reality it isn't. The explanation in the text is correct for a simple (2 or 3) redundant sensor logic. But Tc is calculated based on six sensors, and 4 are bypassed at low temp like a LBLOCA. If you want to keep this format (i.e., 'U' or 'R' quality tags) PZR level would be better. Recommend the following alternative question: "The reactor automatically tripped. The US has just entered EOP 2525. No operator actions have been taken.ll Using the attached copy of the SPDS Display, identify the event that has occurred? A.
Excess Steam Demand inside Containment. B. Steam Generator Tube Rupture on #2 S/G. C. Loss of Coolant Accident D. Loss of Feedwater."
The attached displays were copied off of the simulator during a LBLOCA. Page 2 (1 min Post LOCA) should be used for this question. Using these display, we could ask dozens of questions - call me to explore the options.
- 5. (DEJ 01/10/05) I don't think your Q matches K/A, and is minutia. I really like utility Q, but need screens printed in color.
- 6. (JMD 01/31/05) Recommend implement licensee recommendations.
- 7. (PAP 02/07/05) Changed per licensee recommendations. Need SPDS handout from licensee for 1 minute after initiating fail open of #2 FRV at full power, followed by LBLOCA concurrent with the reactor trip.
- 8. (PAP 02/17/05) Capitalized NO in stem.
- 1. (JMD 11/10/04) Okay.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (RJC 12/13/04) Change "from the answers below" to "from the choices below".
- 4. (PAP 12/13/04) Changed "answers" to "choices" as recommended in #2 above.
- 5. (DAP/RJA 12/16/04) Okay. Was it intentional to have a failed middel seal on "C" RCP?
- 6. (PAP 12/28/04) Fixed typo in stem.
- 7. (DEJ 01/10/05) Is pump nomenclature no correct (1A, 1B, 2A, 2B) vs (A, B, C, D)? Is 200# d/p criteria part of a objective where it is required from memory? If not, fully fail the seal. Same wiith S/D vs trip criteria.
- 8. (PAP 01/12/05) Yes, nomenclature correct. Also, Obj RO-32 of RCS lesson requires the applicant to know operating restrictions for one and two failed seals. Another objective requires operator to know basis for all procedural cautions and notes. No changes required.
- 9. (PAP 02/17/05) Capitalized NOT in stem.
Page 2 of 25 Friday, April 22, 2005
- 1. (JMD 11/26/04) K/A mismatch. Doesn't address console ops. Modification suggestion: An RCS leak occurs which lowers level in the pressurizer by 10%, and is then isolated by the crew. The RO restores level in the pressurizer. With no auto makeup, VCT level will decrease by ______, and the operator will have to perform a manual makeup of
_________ gallons to restore VCT level.
- 2. (PAP 11/30/04) Comment resolved by adding to stem so that applicant must identify whether controller output must be raised or lowered to address the event.
- 3. (JMD 12/08/04) Reviewed changes. No comments.
- 4. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 5. (RJC 12/13/04) Underline "approximately" in stem.
- 6. (PAP 12/13/04) Database will not allow underlining of individual word in a field.
- 7. (DAP 12/16/04) Okay. Recommend changing "If auto makeup fails to start" in stem to "With no makeup to the VCT".
- 8. (PAP 12/28/04) Changed stem as recommended by licensee.
- 9. (DEJ 01/10/05) Fine.
- 10. (PAP 02/17/05) Capitalized NO in stem.
- 11. (PAP 02/18/05) Changed "prior" in stem to "rate at which it was decreasing".
- 12. (RLC 03/15/05) Recommend rewording question to remove "fill-in" design and clarify soliciting of knowledge of size difference between PZR and VCT through the use of specific numbers in rate of lowering. [Proposed: change stem to provide initial rate of pzr decrease (2%/10 min), change choices to provide rate of VCT decrease (4%/10 min, 1%/10 min, 6%/10 min, 1.5%/10 min]
- 13. (PAP, JMD 03/16/05) Modified structure of question as recommended. Discussed with licensee.
- 1. (JMD 11/26/04) Distractors C and D are the same. Try a runout flow distractor.
- 2. (PAP 12/07/04) Modified C and D to provide SI-306 position. Valve is full open in C and full closed in D.
- 3. (JMD 12/08/04) Reviewed changes. No comments.
- 4. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 5. (RJC 12/13/04) Are we sure B, C, D are not potential causes. Can we eliminate "could" from the stem?
- 6. (PAP 12/13/04) Deleted "could" from the stem as recommended.
- 7. (DAP 12/16/04) Okay. Change "Total SDC RHR Flow" to "SDC Total Flow". Change distractor B "at" to "is".
- 8. (PAP 12/28/04) Changed as recommended by licensee.
- 9. (DEJ 01/10/05) Capitalize "oscillating" in stem. Good Q.
- 10. (PAP 01/10/05) Changed as recommended by Don.
- 1. (JMD 11/26/04) Reviewed. No comments.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (DAP 12/16/04) Okay. Change 300°F to 280°F. Greater than 300°F is not allowed per 2310 Step 3.3. 300°F is too close. Change "thermal barrier" in Choice A justification to "letdown heat exchanger".
- 4. (PAP 12/28/04) Changed as recommended by licensee.
- 5. (DEJ 01/10/05) Good Q.
- 1. (JMD 11/26/04) Verify the AOP doesn't require the operator to verify heaters on. If it does, reword stem: "Which of the following actions by itself would maintain ..".
- 2. (PAP 11/30/04) Moved d to c, c to b, and b to d which makes c the correct answer. Maintaining equal number of a's, b's, c's and d's on test as the correct answer.
- 3. (PAP 11/30/04) Modified the stem as recommended to read "following actions, taken by itself ..".
- 4. (JMD 12/08/04) Reviewed changes. No comments.
- 5. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 6. (RJC 12/13/04) Change "itself" to "themselves" in stem.
- 7. (PAP 12/13/04) Changed as recommended in #6 above.
- 8. (DAP 12/16/04, RJA 12/21/04) Okay.
- 9. (DEJ 01/10/05) Good Q.
- 10. (PAP 02/17/05) Capitalized NOT in stem.
- 11. (RLC 03/15/05) Recommend modifying first sentence [of stem] to indicate the PT that is controlling, instead of the PT that "is NOT" controlling.
- 12. (PAP, JMD 03/16/05) Modified first sentence in stem as recommended. Discussed with licensee.

- 1. (JMD 11/26/04) Reviewed. No comments.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (PAP 12/13/04) Identified as memory level.
- 4. (DAP 12/16/04, RJA 12/21/04) Okay. Change distractors from "or more" to "greater than or equal to".
- 5. (DEJ 01/10/05) May want to ensure "D" can't be argued. May want to lower to 20 psi or swap #2 and #1. Good Q.
- 6. (PAP 01/28/05) Changed as recommended by Don.
- 7. (PAP 01/31/05) Changed as recommended by licensee in Item 4 above.
- 1. (JMD 11/26/04) Reviewed. No comments.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (RJC 12/13/04) Add "IAW EOP-2536, Excess Steam Demand Event" to the stem. Are these immediate actions? If yes, not naming procedure okay. If they are supplemental actions, will naming the procedure give away answer?
- 4. (PAP 12/13/04) Modified stem as recommended in #4 above.
- 5. (DAP/RJA 12/21/04) Okay. Change Choice C from "Manual Loading Stations" to "Controllers on C-05".
- 6. PAP 12/28/04) Implemented licensee recommendations as follows: added "on Panel C-05" to stem, changed "Manual Loading Stations" to "Controllers" in Choice, modified "momentarily shift" in choice to "shift #2 .. momentarily to
..", swapped Choices C and B.
- 7. (DEJ 01/10/05) May be able to argue "A" correct since it is in procedure. I think could mitigate event depending on leak location. (Break on AFW line). Why has AFAS not actuated? Do they have auto AFAS block?
- 8. (PAP 01/10/05) In reference to comment that "A" may be argued correct - this is bank question, licensee had no comment about the distractor, question asks what action "to mitigate this event". AFAS has not actuated because of actuation time delay.
- 9. (JMD 01/31/05) Reviewed changes. Ok.
- 10. (PAP 02/17/05) Capitalized NOT in stem.
- 1. (JMD 11/26/04) Distractor C may be a second correct answer. No longer effective doesn't mean stop trying.
Possible alternatives: C, D: Depressurize RCS by steaming ADVs at max rate.
- 2. (PAP 12/07/04) Modified C and D as recommended.
- 3. (JMD 12/08/04) Reviewed changes. No comments.
- 4. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 6. (PAP 12/13/04) Question requires a general understanding of the effect of a sustained loss of all feedwater. In order to answer question an RO must know the general event mitigation strategy (once-through cooling) and the thermohydraulic response of the plant. At given RCS temperature, RCS pressure will stabilize above shutoff head of HPSI pumps. 88 gpm charging flow will not be sufficient to remove decay heat. Water inventory will drop until there is too little left to maintain RCS pressure, at which point HPSI will inject. Core uncovery is likely. I think this question requires RO level knowledge. Will wait for feedback from licensee review.
- 7. (DAP 12/17/04, RJA 12/21/04) Okay. Fix temperatures in Justification for Choice A to match temperatures in question stem.
- 8. (PAP 12/28/04) Fixed justification as recommended by licensee. Changed "deg F" to "°F" in stem and justification.
- 9. (DEJ 01/10/05) Put trends on parameters. Make Thot > 596°F. Great Q.
- 10. (PAP 01/28/05) Added trends to parameters as recommended by Don. Left Thot at 584°F. Temperature sufficiently high to set up situation where once through cooling will not be effective at keeping the core covered.
- 11. (PAP 02/17/05) Capitalized NOT in stem and two Choices.
- 12. (PAP/JMD 03/07/05) Changed all choices to focus applicant attention on need to evaluate current RCS conditions and to ensure distractors balanced.
- 13. (RLC 03/15/05) Recommend rewording question to NOT give plant indications that would imply Operators violated EOP for Loss Of All Feedwater by letting SG level drop below 70" without taking any action. Also, modify distractors to include specific plant operating criteria that is true for OTHER plant emergencies not specific to that solicited by the question stem.
- 14. (PAP, JMD 03/16/05) Modified question as recommended. Discussed with licensee.
- 1. (JMD 11/26/04) Reviewed. No comments.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (DAP/RJA 12/21/04). Okay. This meets the NC requirements but these temps would have us riding the safety vlvs. EOP 2530 would have us cooling down by 2 hrs post event. You might consider lowering these temps by 80°F which would equate to about a 60°/hr cooldown rate.
- 4. (DEJ 01/10/05) Good Q. Take their [licensee] recommendation. Supply steam tables.
- 5. (PAP 01/28/05) Will provide steam tables to applicants. Lowered temperatures as recommended. Lowered all temperatures by 80°F in choices. Lowered RCS pressure in Choices C and D to ensure SCM is 25°F and 65°F for Choices C and D respectively.

- 1. (JMD 11/26/04) Reviewed. No comments.
- 2. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 3. (RJC 12/13/04) We may get a challenge on need to memorize ARPs.
- 4. (PAP 12/13/04) Identified as memory level.
- 5. (DAP 12/17/04, RJA 12/20/04) Okay. Change "PPO" to "SPO" in stem (2 places). Choice A may be considered a correct answer due to the following: a) the plant is not stable (62% and lowering at 5%/hr), b) problem with the B MFP speed control system. These two consideration may cause the examinee to conclude that the plant is too unstable to permit control of #2 S/G with MFP speed control. Recommend [underlined] having the plant stable at some power level (eg., 80%, "B" Condensate Pump out for repairs.) Change Choice A to read: place "B" MFP in manual and control speed manually to maintain #2 S/G level. Don't give them the option to trip.
- 6. (PAP 12/28/04) Spoke to RJA on phone. Their concern is that operator will opt to trip based on existing problem with feed pump speed control. Changed stem to indicate power is being reduced slowly to remove a condensate pump from service. Changed PPO to SPO in two places.
- 7. (DEJ 01/10/05) I agree with licensee recommendations. Should get trip option out.
- 8. (PAP 01/28/05) Modified stem further by replacing "a transient occurs indicated by multiple alarms" with "when SPO reports FRV Locked alarm and white lights out". Licensee accepts that changes (from 5% ramp to 2% ramp and MFW pump repair to condensate repair) take away justification for ordering a reactor trip based on FRV locked. Leaving trip option as distractor in Choice A.
- 9. (JMD 01/31/05) Reviewed changes. Ok.
- 10. (JMD 02/17/05) Remove the downpower from the stem, to ensure Choice A cannot be argued correct.
- 11. (PAP 02/17/05) Changed as recommended.
- 1. (JMD 11/26/04) Just put in a "fail to start" distractor. Example: A) EDG fails to start due to lack of control power, B) EDG starts, fails to load due to lack of control power, C) EDG starts and loads, mechanical trips only available, D)
EDG starts and loads, all trips available due to alternate control power.
- 2. (PAP 12/07/04) Modified the choices to include a fail to start. Added a "trips on overspeed" choice to ensure question structure fits the required attributes of NUREG 1021. New structure: two choices for "doesn't run" and two choices for "runs".
- 3. (JMD 12/08/04) Reviewed changes. No comments.
- 4. (JMD 12/08/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
(RJC 12/13/04)
- 5. (PAP 12/13/04) Identified as memory level.
- 6. (DAP 12/17/04, RJA 12/22/04) Okay.
- 7. (DEJ 01/10/05) Longest answer is correct. Look at bank Q, nearly all distractors same length. Add some B.S. to A and B.
- 8. (PAP 01/28/05) Added to Choices A and B as recommended by Don.
- 9. (JMD 01/31/05) Reviewed changes. Ok.
- 10. (PAP 02/17/05) Capitalized NOT in Choice A.
- 1. (JMD 11/26/04) Overly involved? Other indications of a leak? Sump, annunciators, pressure alarms? Normal flows expected knowledge?
- 2. (PAP 12/07/04) Per conversation with Dan Pantalone, MS2 expects applicants to know normal system flows.
Question left as-is, pending feedback from licensee review.
- 3. (JMD 12/08/04) Reviewed changes. No comments.
- 4. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 5. (DAP/RJA 12/21/04) a) Change "at 100% power" to "in MODE 3", because a loss of DV-10 would cause both MSIVs to close resulting in a plant trip. In-house electrical loads transfer from the RSST to the NSST. The loss of DV-10 prevents the breakers on Facility 1 from operating resulting in a loss A SW and RBCCW Pumps and the A D/G (F6433 and F6397 will be 0 gpm). b) Replace stem statement about TS action statement with "B RBCCW Hx is aligned to provide minimum flow for the A SW header". If the "B" SW Pump is properly aligned, then the Tech Spec Action only applied during the swap. Once complete, the US would log out of the Action Statement. c) Change parameters 5180 to 8885, 1220 to 785, 5350 to R150?, 1165 to 850, 145 to 100. d) Change HIGHER to LOWER in B and C. The flow transmitter is downstream of the HX SW TCV.
- 6. (PAP 12/28/04) Changed initial condition to MODE 3. Changed Choice C leak location to "downstream of..".
Choice B became D, D became C, C became B. Modified flows to 8885, 795, 8965, 850, and approx 100. Replaced statement about TS action statement with recommended sentence about 'B' SW Pump alignment.
- 7. (DEJ 01/10/05) Unsure which is final form of Q, definitely meets K/A. Pretty high difficulty w/o procedures and prints.
- 8. (PAP 02/17/05) Capitalized NO in stem.
- 9. (PAP 02/18/05) Changed question wording for clarity.
Page 5 of 25 Friday, April 22, 2005
- 1. (JMD 11/26/04) Stem focus: conditions indicate overpower, possibly due to operator action. Why continuous withdrawal? K/A mismatch: "Rx trip switches" are involved how?
- 2. (PAP 12/07/04) Trip switches involved in correct answer. Applicant must realize that correct action is to depress reactor trip pushbuttons. Interpreting "pushbutton" and "switch" as equivalent in context.
- 3. (PAP 12/07/04) Modified stem to indicate rods were manually withdrawn just 5 steps to establish +0.5 dpm SUR.
Plant response is consistent with large rod withdrawal, in excess of amount manually withdrawn by PPO.
- 4. (JMD 12/08/04) Reviewed changes. No comments.
- 5. (RJC 12/13/04) Reviewed. General comments: Identify cognitive level of question and whether handouts provided.
- 6. (RJC 12/13/04) Typo. "CEAs are have been .." in stem.
- 7. (PAP 12/13/04) Typo corrected. Deleted "are".
- 8. (DAP/RJA 12/20/04) Add "DPM" to choice. Change Choice D to ".. Open 'B', 'C', and 'D' steam dumps. Existing choice not plausible as MSIVs are already open.
- 9. (PAP 12/28/04) Added "dpm" to choice.
- 10. (DEJ 01/10/05) Need to add other data in stem to match distractors: S/G level/trend, SUR/trend, RCS temp/trend.
- 11. (PAP 01/28/05) Sufficient information provided by high power trip resets to require applicants to determine additional feedwater is required if that power level is to be maintained. The high power trip resets also indicate that beyond POAH. SUR will no longer be the indicator of rate of power increase. No need to modify stem.
- 12. (JMD 01/31/05) Change "0.5 dpm SUR" to "positive SUR". Otherwise okay.
- 13. (PAP 01/31/05) Changed Choice B as recommended.
- 14. (DAP 02/17/05) Change "red High.." in stem to "all High".
- 15. (PAP 02/17/05) Changed as recommended. Capitalized NO in stem.

- 3. (DAP/RJA 12/20/04) Change Choice C to "It is fully inserted, but indication is lost due to loss of VR-11". While the
[existing choice] is not a completely correct answer, it is arguably correct. The CEA may be assumed to be at any position between 2 steps withdrawn and at least 1 step inserted. With the given conditions, there is no other indicaion of actual CEA position. (C is a subset of D.) The intent of this distractor was to see if the students could remember that the PPC indication is an input to the "blue" llight for the S/D CEAs.
- 4. (PAP 12/28/04) Did not accept recommendation. Licensee contends that the choice is "agruably correct".
However, the choice states CEA is inserted AT LEAST 10 STEPS. Based on indications, this cannot be concluded.
The CEA MAY be inserted 10 STEPS, or 9 or 8. In fact, with given indications, can only conclude CEA is not fully withdrawn.
- 5. (DEJ 01/10/05) K/A mismatch. K/A - Dropped control rod. Q - All rods in on trip. Rx trip not equal to dropped rod.

- 3. (DAP 12/21/04, SRM 12/22/04) Recommend changing to Choice D as correct answer and modify D to equal, equal, equal. I asked our simulator thermo/heat xfer engineers to evaluate this question (they are on the security agreement).
My feeling was that both S/G pressures would be equal because they both were dumped to the condensor via the 'A' steam dump vlv. The engineer pulled a recent simulator test designed to evaluate the fidelity of the simulator as compared to some standard. The test was 100% pwr with a deenergization of the 'A' RCP. Notice the pressure of #1 and #2 S/G s are identical. (See curves #8 thru 15). The only slight difference is betweem feed flow. That was due to the feed reg bypass valve throttling to a slightly different position. Just the way our simulator is groomed.
- 4. (PAP 12/28/04) Don't want to accept recommendation because puts applicants in the dilemma of choosing between theoretical response using laws of physics vs observed response based on small magnitude of actual changes. Recommend instead changing stem to "steady at 80% power, bkr trips, reactor fails to trip, if no operator actions compare conditions".
- 5. (DEJ 01/10/05) I think 'C' is right, heat xfer lowers on loop w/idle RCP. Pressures = w/MSIVs open.

Per Attachment 3 of MP-26-EPI-FAP09, the authorization of < or = 25 Rem requires "lifesaving or protection of large populations". A General Emergency may meet the "protection of large population" requirement, but the exposure limit does not have to be 25 rem, it could be 15 rem, or 12 rem etc. The only specified automatic upgrade is 4.5 rem/hr when an Unusual Event or greater is declared.

"Managable" further eliminates calling security which may also prompt a call to Unit 3. Essentially any abnormal event on one unit results in a courtesy call to the other unit.

- 1. (JMD 01/03/05) How does this relate to the K/A?
- 2. (PAP 01/04/05) K/A addresses knowledge of loss of source range as applied to associated guidance in the emergency operating procedures. EOP-2540A, "Functional Recovery of Reactivity Control" provides an acceptance threshold based on source range indication after a trip. The technical guide for this EOP states that reactor power is expected to fall below this value within 15 minutes after a reactor trip. This question tests knowledge of this guidance and the operation of the nuclear instruments in that the applicant must apply this knowledge in demonstrating an ability to identify correct operation of the source range instruments. By knowing what to expect of these instruments, an operator will be able to recognize improper operation of the source range when called to use them during implementation of the EOPs.
- 3. (DEJ 01/10/05) Appears as a K/A mismatch, no evident loss of SRNI's. May not be EOP guidance on loss of SRNI's, only in AOP's.. Pick new K/A and Q.
- 4. (JMD 01/11/05) Agree with Don. Not a good K/A match. Need to modify question.
- 5. (PAP 01/12/05) Replaced originally developed question with new question developed by JMD. Original question follows: STEM: The plant has been operating at 100% for two months when the following occurs:ll- TURBINE THRUST BRG WEAR TRIP alarm (B-26 n C-06/7) is receivedl- main turbine automatically tripsl- reactor trip breakers remain closedllThe PPO manually trips the reactor by opening the CEDM MG set breakers.llApproximately 18 minutes after the reactor trip, which of the following sets of indications will be displayed on Channel 'A' Wide Range Excore Nuclear Instrument? CHOICES: A) 1E-7 % and 1E4 cps B) 1E-6 % and 1E5 cps C) 1E-5 % and 1E4 cps D) 1E-4 % and 1E5 cps. JUSTIFICATION: CHOICE (A) - NO WRONG: Overlap is off by 2 decades. VALID DISTRACTOR: Proper counts per second indicated. CHOICE (B) - NO WRONG: Power is inconsistent for time after shutdown. Overlap is off by 2 decades VALID DISTRACTOR: 1E5 cps expected (per EOP Tech Guide) for 15 minutes after trip CHOICE (C) - YES EOP Technical Guide state that 1E-4% expected 15 minutes after a trip. With normal minus-one-third decade per minute negative SUR post-trip, reactor power should drop another decade during the time between 15 minutes after and 18 minutes after the trip. CHOICE (D) - NO WRONG: Power is 1 decade higher than expected. VALID DISTRACTOR:
Proper overlap indicated. Power level consistent with 15 minutes after trip.llFor purpose of K/A catalog, Millstone Unit 2 considers the Wide Range Nuclear Instruments to be "source range" when below 1E-4%. The instruments are considered as "intermediate range" when reactor power between 1E-4% and 0.1%.

- 4. (DAP, SRM 01/20/05) There is no correct answer to this question. Both BA pumps are Z2 and do not start due to loss of VA-20. Without a running BA pp, there is no reason to open CH-514. Both gravity feed valves (not mentioned in question) are Z1 and will both open on SIAS at 1672 psia. Also, CH-501 is Z1 and the 'B' and 'C' charging pump will be running at 1672 psia.

- 1. (JMD 01/03/05) Check at facility (CAF) because LPSI are used for boron precipitation or for cooling flow?
- 2. (PAP 01/04/05) Completely rewrote the question. The original unworkable because a single HPSI provides adequate flow for long term cooling. Original question was as follows: During recovery from a Large Break LOCA, a LOSS of which of the following pumps will have the GREATEST impact on LONG TERM CORE COOLING? A-charging pumps, B-reactor coolant pumps, C-high pressure safety injection pumps, D(key answer)-low pressure safety injection pumps. Original justifications: CHOICE (A) - NO WRONG: Charging pumps do not provide sufficient flow to maintain the core cooled. VALID DISTRACTOR: Charging pump start on SIAS and inject to the core. CHOICE (B) - NO WRONG: Reactor coolant pumps are not used for long term cooling in a post-LBLOCA situation. VALID DISTRACTOR: Reactor coolant pump restart is addressed in the EOPs for special situations, such as during SGTR.
CHOICE (C) - NO WRONG: EOP steps shutdown HPSI during post-LOCA cooldown. VALID DISTRACTOR: HPSI is designed for high pressure injection in small break situations. CHOICE (D) - YES Recovery from a LB LOCA is dependent of maintenance of core cooling via flow through the core and out the break. LPSI is designed to provide a high volume/low pressure flow of borated water to the core and can maintain stable cold conditions using the SDC heat exchangers to remove decay heat.

- 3. (DEJ 01/10/05) Good Q.
- 4. (RJA, 01/20/05) The facility 1 HPSI pump is required for boron precipitation control if facility 2 is not available.
Therefore answer C is correct. B is incorrect.
- 5. (DAP 01/20/05) Answer B is not correct. While the remaining HPSI does provide sufficient injection flow, there is no pump to provide boron precipitation, which is part of the long term heat removal strategy.
- 6. (PAP 01/27/05) Need to talk to Dan before changing. Stem says hot leg break. Should not need boron precipitation control.

In our opinion, this question relies on the student knowing alarm setpoints (i.e., would 100°F be ok or not?). This does not distinguish between competent and incompetent operator.
- 7. (PAP 01/27/05) Changed stem as recommended. Operators should be able to recognize off-normal conditions to prevent exceeding limits. SP-2619A-002, "Control Room Daily Surveillance, MODES 1 & 2" even has a section for compensatory checks of quench tank level, temperature and pressure while RC-200 AVMS is failed.

Change Choice D to "lower", vice "higher". 1) Examinees are not required to know transmitter numbers and what they control. The above modification should be considered. 2) The modification to 'D' makes it the most correct answer. Steam flow through an ADV is not sensed by the S/G water level control system. Therefore the only SGWLC signal that would compensate for the excess steam flow is the deviation between level setpoint and actual level. Now things get complicated. If the controller is a proportional controller the level will stabilize below setpoint, which I'm not sure of. If the controller is integral/differential, the level will return to setpoint, assuming it responds quick enough to avoid a trip. All I can say is 'D' is the most correct answer [with recommended change of higher to lower], but I can't say it is really correct.
- 5. (PAP 01/27/05) Added "for the #2 ADV" to the stem as recommended. Added "assume no operator action" to stem, as recommended. Changed "recover" to "stabilize" in choices, as recommended. Left Choice D as "higher".
From FSAR description, the controller has an integral feature which ensures that output adjusts as necessary to return controlled parameter to setpoint. Choice B remains as the correct answer.

- 4. (DAP 01/21/05) Ok.
- 1. (JMD 01/03/05) Relevance? Leave as is for CAF (Check At Facility). Suggested fallback question: Which of the following describes the response of the EDG if power is lost to the governor? A-Control will shift to the mechanical governor, which will maintain the EDG at present speed. B(key answer)-Speed will rise to the mechanical governor setpoint. C-Speed will lower to the mechanical governor setpoint. D-The EDG will shutdown.
- 2. (DEJ 01/10/05) Good Q.
- 3. (RJA 01/25/05) We don't feel that operators should know specifically how the fuel racks are positioned on an automatic start. This does not distinguish between a competent and an incompetent operator. It may be more appropriate to ask how load is controlled on an emergency start or what happens to D/G speed control on a loss of DC.
- 4. (PAP 01/27/05) Governor oil boost is covered in operator training EDG lesson material. Air start isolations are identified as needing to be open to "governor oil booster". OP-2346A, "Emergency Diesel Generators" has sections for manual start of a diesel from the control room which direct the operator to verify fuel racks in minimum position and manipulate slow speed switches. Print 26010, "Fuel System" shows the governor hydraulic oil booster supplied from starting air tied into the governor actuator, which is shown controlled by the Woodward 2301A Governor. Seems appropriate that operator should know the purpose of the governor oil booster, to position the fuel racks to full fuel position on engine start, to ensure engine reaches rated speed within required TS time limit. Recommend leaving question as-is.

- 3. (DEJ 01/10/05) Add "Auto" to A and B.
- 4. (PAP 01/11/05) Should leave choices A and B as is. Choice A is a valid distractor because this valve is opened BY THE OPERATOR to cross-tie Unit 3 IA to the Unit 2 SA system. The suggested change could reduce the discriminatory value of this question.

- 10. (RLC 03/15/05) "C" IAC is being retired in place, replaced by a new "D" IAC and stated it is in service suppling BOTH Instrument Air and Station Air..
Choice "C" (opening of 2-SA-10.1) will also result in the closure of 2-SA-11.1. When this valve closes it isolates the Station Air System and could, conceivably, isolate the rupture, depending on the as yet unknown system lineup when the new "D" IAC is placed in service. [Recommend question setup with new "D" IAC in service]

- 2. (DEJ 01/12/05) High LOD Question, But OK, I nuked it out.
- 3. (DAP 01/21/05) Delete "at" in stem. This question does not distinguish between a competent and non-competent operator. We do not require our operators to know all the ESAS-actuated components and which modules control them. We do not expect our operators to know which components can not be overriden.
- 4. (PAP 01/27/05) Removed "as" from stem (typo.) Objective PEO-7K in the containment systems lesson requires that an operator be able to "describe the relationships between the Containment Systems and the following: ESAS (SIAS,CIAS,EBFS,CSAS,AEAS)". The sentence in the lesson material which explains that the CIAS pump trip signal cannot be overriden and why has a margin note tying the knowledge to the objective. The ESAS lesson material (ESA-01-C) explains that "five components cannot be overridden: both containment sump pumps and the three RBCCW temperature control service water valves". Applicant should not be expected to know which modules control which components. However, the applicant should know enough about the effect of CIAS on the containment sump pumps and associated valves in order to determine that one or more actuation relays have failed to actuate. This knowledge, in conjunction with knowledge sufficient to eliminate the distractors is enough to identify the correct answer. Recommend leaving question as written.
- 5. (JMD 01/31/05) Reviewed. Change Choice D to "An actuation module for CIAS has failed to actuate".

Ask utility which option is better.

- 3. (DEJ 01/12/05) Good Q. Another Hard Q. I did not know the 1135°F number.
- 4. (DAP 01/21/05) Is it a requirement for an operator to know the temperature at which thermal recombination of H2 and O2 occurs? We don't believe that this distinguishes between a competent and an incompetent operator.
- 5. (PAP 02/07/05) Changed question per recommendations to ask time to hydrogen concentration at limit.
- 6. (DEJ 02/09/05) Good Q. RO knowledge? Check learning objectives.
- 7. (PAP 02/09/05) Question relates to objective-based knowledge. Obj HCS-00-C RO10: Describe the source(s) of hydrogen following a loss-of-coolant accident, including expected concentrations at various elapsed times.
- 8. (RLC 03/15/05) Required knowledge of the original question does not distinguish between a safe and unsafe license Candidate. To successfully answer the question, the candidate must assume the plant has had a LBLOCA, assume NOTHING worked to save the core from extensive damage (only way to get a substantial amount of H2 production), assume BOTH recombiners are unavailable and assume nothing has been done to mitigate continued damage to the core for 12 days, then PREDICT what containment hydrogen concentration will be, FROM MEMORY. If the original question MUST be used, then the graph referenced in the Training Materials [Figure A2 of concentration vs.
time after event)) required to answer the question should be provided in the Applicant Handout.
- 9. (PAP, JMD 03/16/05) Modified choices to address licensee comment. Kept question as it is reasonable to expect applicants to remember that time to reach 3% is on the order of weeks rather than hours or days. Discussed with licensee.
- 1. (JMD 01/10/05) Reviewed. No comments.
- 2. (DEJ 01/12/05) Great Q. Note: A is correct on a B+W Plant.
- 3. (RJA 01/20/05) [Combine transmitter and steam dump stroke by adding following to stem] "A Steam Dump Main Steam Pressure Transmitter, PT-4216, output drifts high causing [steam dump] to stroke to approx 30% open." Change 5% to 3% in each choice. Change "taking" to "placing the" in each choice. Change "lowering output to 0" to "in the Close position". We operate in "Load Limit" which maintains the Turbine Control Valves at a fixed position. If a Turbine bypass valve were to open at power, steam pressure to the Turbine would lower resulting in a decrease in Turbine load.
Additionally, RCS temperature would lower resulting in a power increase. The magnitude of each is difficult to determine. A combination of A and B would be correct. [Correct answer is] "Turbine load will decrease and reactor power will rise. The operator can stop ..". See question #82.
- 4. (DAP 01/21/05) I agree with D. Ashey.
- 5. (PAP 01/28/05) Changed stem as recommended. Changed choices per recommendation regarding the "3%", the "placing the", the "..close position". Added time in core life to stem to ensure applicant has information needed to determine that steam pressure change will be so small as to leave turbine load relatively constant throughout transient.
When evaluated against other possibilities, an applicant will be able identify the correct answer. The alternative suggested, which is to say that turbine load decreases could be challenged on the basis that the change is almost imperceptible. The better choice is to describe load as constant. Plant response described in the answer to this question differs from that described in Question #82 because of the magnitude of the primary temperature drop and the amount of excess steam demand. One possible alternative approach would be to say that "turbine load decreases LESS THAN 3% in the correct answer, as opposed to EQUAL TO in the distractors. This alternative eliminates the in-exactness of the term "relatively", but could then introduce uncertainty in that actual power change will be very much less than 3%. Recommend leaving correct answer left as written. Discussed with DAP. He and RJA will review further.
- 6. (PAP 02/02/05) Modified per latest recommendations of DAP/RJA by changing "turbine load relatively constant" to "turbine load will decrease by less than 3%".

- 1. (JMD 01/31/05) Word-engineer Choices A and B. Suggestion: "to ensure .. accurately indicates.."
- 2. (PAP 01/31/05) Changed as recommended.
- 3. (DEJ 02/07/05) Are C&D kinda the same thing? Is "B" plausible, talks pressure control and stem is inventory control.
- 4. (BCH 02/08/05) Response: C&D are similar but different - and both are clearly incorrect. C addresses an abnormal condition (pzr level control fails) while D addresses an emergency condition (what is the appropriate procedural transition). B is less plausible than C or D if pzr level were to drop quickly, pressure would also drop (7.5psia/% pzr lvl).
An applicant could select this choice if he/she thought that the rapid drop in PZR level caused a drop in PZR pressure and therefore may have created a problem with subcooling as pressure went down. Bottom line - it is often hard to come up with plausible distracters for "reasons" questions that are also clearly wrong. I am open to any suggestions that could improve this one.
- 5. (PAP/JMD/RJC 03/09/05) Evaluated LOK of question. Re-categorized as lower order.
- 6. (RLC 03/15/05) Pressurizer level of 20% and dropping requires the RO to verify proper operation of the PZR level control system. When queried of the conditions of PZR level by the US, the RO is SIMULTANEAOUSLY asked for the value and direction of RCS subcooling. The US does not query them separately. Therefore, the RO's are use to giving BOTH conditions in one act AND performing the contingency of step #3 per these conditions. The original Choice "C" is PART OF those contingency actions that are performed and, therefore, this is a "trick" question in regards to what "specific" SUBSTEP is the stem trying to solicit.
- 7. (PAP, JMD 03/16/05) Capitalized SUBCOOLING in stem for emphasis. No other change required. Discussed with licensee.

- 4. (BCH 02/08/05) I swapped C and D distracters but failed to swap the justification.. I dont think this is double jeapardy because in Q55 we test a loss of DV-10 and in Q-56, we test a loss of VA-20. These power supplies do different things. It may be over-sampling - in that we are testing loss of AFW power supplies 2x - that is the way the sample plan rolled but Q55 does not compromise Q56 (you do not need to get the answer to Q55 in order to answer Q56).

(MB-02642)
- 2. (JMD 02/02/05) Setup is confusing. Is IA pressure decreasing because of leak? If so, the RBCCW/Fire water distractors are implausible. If not, need to provide information as to why pressure decreasing. Did a compressor trip?
Also, better match to KA would be "what needs to be done and for what purpose" (i.e., to ensure remote control of steam dumps, etc.)

This does not meet the overlap condition (OVLP) condition because RG-7 and RG-5 are not adjacent groups. Note that if you had an OVLP condition, you will also meet the OOS (first) condition. However, it is possible to meet the OOS condition but NOT meet the OVLP condition. This is now the new premise of the question. In addition, I want to provide a core mimic so the applicants can determine the relative position of RGs 5 and 7 - to better answer the question about radial or axial flux peaking.
- 5. (JMD 02/09/05) Reviewed. CAF.
- 6. (JMD 02/17/05) Revisit this one. Need a situation with operational implications. Example: extension shaft not coupled.
- 7. (BCH 02/23/05) Changed question to test what happens if the CEA extension shaft is not coupled and the reactor is started up.
- 1. (BCH 02/01) Obj RWV-00-C RO5 As given in OP 2314B, state the actions required if noble gas or iodine radioactivity limits are exceeded during containment purge to the Main Exhaust System. (MB-03075)
- 2. (JMD 02/02/05) Reviewed. No comments.
- 3. (DEJ 02/07/05) Good Hard Q.
- 4. (JMD 02/17/05) Reword question to delete reference to "flow rate".
- 5. (BCH 02/23/05) Originally, the question asked for "The method of controlling purge flow rate" in part 2 of the question. Although the purge flow rate was indeed "controlled" by opening 2-AC-3, this valve is not normally considered to be a throttle valve and the use of this terminology was thought to be confusing by the licensee. In other words, the operators do not consider 2-AC-3 as a flow control valve although it clearly controls the flow and has a miod position to throttle flow. I changed the question to ask for the path and the valve that controls the flow rate that is in the path. This still meets the K/A because the flow rate is controlled by positioning the valve listed in the correct answer/distracters.
- 6. (RLC 03/15/05) This evolution resulted in the greatest unauthorized release of radiation to the environment that Millstone site has ever experienced. There is NO WAY any operator would even consider performing this evolution without IN-HAND use of the procedure, and they are trained that way. Requiring them to MEMORIZE the procedure driven flow path is counter to management philosophy and good operating practice. [Recommend modifying question to delete reference to AC-3 / AC-57 and to make the choice between EBFAS or main exhaust system to the Millstone or the Unit 2 stack].
- 7. (PAP, JMD 03/16/05) Left question as written. Discussed with licensee.
- 1. (BCH 02/02/05) Note - there are 4 revisions to this bank question. In every case, the correct answer was either A or B. I have added the additional point that the fuel assembly should remain grappled to ensure that no applicant can argue that it would be more appropriate to return the assembly to the core based on refueling experience that it would be quicker to do this than to place it in the sourth saddle area.

- 1. (BCH 02/03/05) This question was developed after shifting the original K/A. As the reference material was reviewed, it became clear that MP-2 Tech Specs appeared to have a "hole" regarding the requirement for WR NI channels during a startup. The question was completed but it is not clear if there is a correct answer because the startup procedure does not clearly identify action to be taken if the number of operable WR NI channels falls below the minimum during a startup.
- 2. (JMD 02/03/05) Change correct answer to "stop CEA withdrawal", based on Step 4.3.3. CAF.
- 3. (DEJ 02/07/05) A.2. does not indicate a time frame, others do.
- 4. (PAP 02/08/05) Added "within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />" to Choice A for symmetry.
- 5. (BCH 02/08/05) Good idea. Looks better from a psychometric perspective.
- 6. (JMD 02/17/05) Reselect the K/A
- 7. (BCH 2/25/05) This is a valid K/A - the problem is that the situation is unfulfilling to operators who would want to take some action if they were in this condition. However, Millstone Tech Specs do not require any action to be taken under this situation. Decided to change the question to test the required tech spec action for a loss of WRL NI channels in MODE 3 as directed by JMD.
- 8. (RLC 03/15/05) The plant enters Mode 2 when Group 4 reaches 72 steps (per OP-2202). Therefore, the question is technically incorrect for the given conditions. Recommend rewording in order to still meet the original K/A, and live within the bounds of required RO knowledge (the detailed requirements of most Tech. Spec. Action statements, especially those listed in "Tables", are NOT required from memory for an RO). Proposed rewording slightly to solicit actions implied by the Reactor Startup procedure, OP-2202, which states that TWO channels of WR NI's are required to perform a reactor startup.

- 6. (RLC 03/15/05) Recommend rewording question to simplify the stem somewhat and to put the emphasis on the ADMINISTRATIVE aspects of the instrument failure, as that is the only concept being tested that is of a license knowledge level. The "system valve response" is more of a non-license concept.
- 7. (PAP, JMD 03/16/05) Question left as written. Discussed with licensee.
- 1. (BCH 02/03/05)
- 2. (JMD 02/04/05) Unrealistic. This is going to require a percentage of the core released into the containment. Won't happen from a SGTR. Possibly add a LBLOCA to the stem, or just ask a question that more simply addresses the KA.
- 3. (BCH 02/07/05) Modified question and choices. Stem no longer refers to a SGTR.
- 4. (DEJ 02/09/05) [Stem] needs to say "a rx trip occurs at 0200."

- 1. (JMD 02/04/05) Ok. Correct spelling of "green" in stem. I am amazed that you actually found a [KA] link.
- 2. (PAP 02/07/05) Changed green light to red light in stem and added function and location for light. Intent is to provide indications that valve has closed.

Change Choice C from "CA system" to "AOP-2575, "Rapid Downpower". While it is true the setpoint per the ARP is 3.8, the actual setpoints are lower, which allows for instrumentation drift. Ctmt pressures of this magnitude would result in tripping the rx, therefore 2525. We reworte the question to indicate a small high energy break in ctmt that would require a rapid downpower, but not a trip.
- 4. (PAP 12/28/04) Changed per licensee recommendation.

While D is still technically correct, someone may think it should be more correct. B may be considered correct if the examinee assumes #2 SG level will continue to increase to greater than 40% without any feed flow.
- 4. (DAP 01/24/05) Change Choices C and D from "continue feed to SGs until both have" to "feed SGs to maintain".
The use of "until both have.." means you can't stop feeding the high SG until the lower SG is greater than or equal to 40%.

Per lesson material, the blowdown rad monitor can be used to identify SGTR, "but due to its low sensitivity, it has been found in the industry not to alarm until around 30 minutes after real tube leaks." Deleted "no other rad monitors rising".

- 1. (JMD 01/18/05) Reviewed. No comments.
- 2. (DEJ 02/07/05) Verify correct per licensee. EOP's active in mode 3 but doesn't seem right to do E-0. Check E-0 entry.
- 3. (PAP 02/08/05) Checked with licensee. With JMD concurrence, changed to MODE 2 situation in stem.
- 1. (JMD 01/31/05) Reviewed. No comments.
- 2. (DEJ 02/07/05) Good Q.
- 3. (PAP 02/17/05) Simplified situation in stem.
- 4. (RLC 03/15/05) Original questions tests the "from memory" recall of a concept that may not be required for several months. [Recommend replacing with Bank Q# 56585.]
- 5. (PAP, JMD 03/16/05) Left question as written. Discussed with licensee.
- 1. (JMD 01/31/05) Reviewed. No comments.
- 2. (DEJ 02/07/05) Good Q.
- 3. (PAP 02/17/05) I messed up question by making changes prematurely. Need to think this through and rewrite. No alternate channel. No PORV position indication. QT temp / press hi ARPs require immediate trip.
- 4. (PAP 02/24/05) Rewrote question as suggested by JMD.
- 1. (JMD 01/31/05) Question asks NEXT corrrect action. Stop LPSI is the next. Only considered a distractor because wrong procedure referenced. As currently written, all choices are correct actions in response to given conditions.
Recommend deleting procedure references and asking which of the following is a correct action. Choice of the correct action shows applicant understanding of the procedure without having to refer to it specifically.
- 2. (PAP 01/31/05) Changed as recommended.
- 3. (JMD 02/01/05) Reviewed. No comments.
- 4. (DEJ 02/07/05) Put procedure reference in stem. Will make it link to 43(5).
- 5. (PAP 02/08/05) Changed as recommended.
- 6. (PAP 02/17/05) Added additional signals to stem (EBFAS, MSI). Capitalized NOT.
- 1. (JMD 01/31/05) Reviewed. No comments.
- 2. (DEJ 02/07/05) K/A Mismatch? What are your thoughts? One of my least favorite K/As.
- 3. (JMD 02/08/05) Disagree. K/A match ok.
- 5. (PAP 02/24/05) Capitalized NO in stem.
- 1. (JMD 01/31/05) KA mismatch. KA says recognize reportable event. Q gives reportable event. Can use a Q that uses both reportable and non-reportable events with times. For example, "which of the following is reportable and the time frame" (two choices reportable, two not)
- 2. (PAP 01/31/05) Changed as recommended.
- 3. (JMD 02/01/05) We'll probably get comments on knowing 4 and 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> reports. Let licensee make suggestions.
