(F/H) (1-5) Cues T/F Partial Minutia Focus Dist Link Units ward K/A Only General comments:

  • When asking the reorder distractors, stating D-A-C-B means the current distractor D should be the new A, current distractor A should be B, etc.
  • Highlighed blocks indicates changes NRC recommends to the submitted question.
  • Too many instances of LOD 4. There should be very few LOD 4 questions on exam, and generally none that are fundamental level of knowledge or tier 3. Question LODs were based on data provided from validations performed. The LOD of a question was subjectively measured at CPNPP in the past resulting in incorrect overall examination LOD. For this exam, data was utilized based on validation results to show the actual LOD of examination questions in an objective manner. NUREG-1021, Appendix A states: A fundamental knowledge question may be easy (e.g., how many inches are in a foot) or difficult (e.g., in what year was the printing press invented). Could not find anywhere in NUREG-1021 that stated a Tier 3 question could not be an LOD=4. All LODs changed as directed on exam.
  • Not meeting Tier 1 guidance means: Does not contain information in procedures, selection of procedures, progression of event, or assessment of plant response over several systems or safety functions, per Feedback Item 401.55. Feedback 401.55 was discussed with CE during the Initial Facility Contact. The guidance provided by the CE at that time was that this New NRC Guidance from Feedback 401.55 was not being enforced yet and as long the question met the K/A it would be acceptable.

Refer to Section D of ES-401 and Appendix B for additional information regarding each of the following concepts:

1. Enter the level of knowledge (LOK) of each question as either (F)undamental or (H)igher cognitive level.
2. Enter the level of difficulty (LOD) of each question a 1 (easy) to 5 (difficult); questions with a difficulty between 2 and 4 are acceptable.
3. Check the appropriate box if a psychometric flaw is identified:
  • Stem Focus: The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
  • Cues: The stem or distractors contain cues (e.g., clues, specific determiners, phrasing, length).
  • T/F: The answer choices are a collection of unrelated true/false statements.
  • Cred. Dist.: The distractors are not credible; single implausible distractors should be repaired, and more than one is unacceptable.
  • Partial: One or more distractors are partially correct (e.g., if the applicant can make unstated assumptions that are not contradicted by the stem).
4. Check the appropriate box if a job content flaw is identified:
  • Job Link: The question is not linked to the job requirements (i.e., the question has a valid K/A but, as written, is not operational in content).
  • Minutia: The question requires the recall of knowledge that is too specific for the closed-reference test mode (i.e., it is not required to be known from memory).
  • #/Units: The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).
  • Backward: The question requires reverse logic or application compared to the job requirements.
5. Check questions that are sampled for conformance with the approved K/A and those K/As that are designated SRO-only. (K/A and license-level mismatches are unacceptable.)
6. Enter questions source: (B)ank, (M)odified, or (N)ew. Verify that (M)odified questions meet the criteria of Form ES-401, Section D.2.f.
7. Based on the reviewers judgment, is the question, as written, (U)nsatisfactory (requiring repair or replacement), in need of (E)ditorial enhancement, or (S)atisfactory?
8. At a minimum, explain any U status ratings (e.g., how the Appendix B psychometric attributes are not being met).

6. Source 7. Status Q LOK LOD 8. Explanation Stem Cred. Job- #/ Back Q- SRO (B/ M / N) (U /E /S)

(F/H) (1-5) Cues T/F Partial Minutia Focus Dist Link Units ward K/A Only I question whether there is a correct answer, since the note in Tech Spec 3.4.5 allows for all RCPs to be secured for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> so zero is actually the minimum. The stem of the question clearly states An RCS dilution is in progress.

Performing a dilution violates the required conditions of the Note in the Tech Spec.

Therefore, RCPs are not allowed to be removed from operation. Could argue that A and B are both correct. It appears to me that if you commenced emergency boration, you would meet the intent of the note in the tech spec. The purpose of the Note is to perform tests that are required to be performed without flow or pump noise. This test is generally performed in MODE 3 during the initial startup testing program, and as such should only be performed once in the life of the plant unless there changes made to the RCS that may cause adverse flow characteristics. The Note is in Tech Specs to allow for testing. It is NOT in Tech Specs to allow the plant continued E operation outside of LCO requirements due to the 1 F 3 X M S trip of an RCP (as stated in the question).

Attempting to meet the requirements of the Note after an RCP trip is not ONLY wrong because of the information provided above but would also be a violation of Tech Specs. The requirements of the Note were not met before the RCP trip as a dilution was in progress. Attempting to meet the requirements of the Note after the RCP tripped is not allowed (i.e. both conditions of the Note must be met prior to securing RCPs). Therefore, attempting to emergency borate to meet the requirements of this note is clearly wrong and would be a violation of Tech Specs. However, it is plausible because an examinee could believe emergency boration is an option based on attempting to incorrectly meet the Note. Four operable RCPs in mode 3 is not plausible. Four operable RCPs in Mode 3 is our normal configuration. Very rarely do we ever have Inoperable RCS Loops in Mode 3. 5 validators missed this question by selecting C as the correct answer. You can answer this question by Rev. 11

This is an incorrect statement as the question is currently written, especially based on your comments abovethe fact that an RCS dilution is in progress is key information for the examinee.

Swap distractors A and B, and C and D such that part 2 reads short-to-long, making B the new correct answer. Fixed as directed. LOD should be 3. LOD fixed as directed, however, question LODs were set based on validation results. This question was validated by 14 operators and 7 missed the question. This results in a 50% pass rate and an LOD of 4.

Question now SAT 2 H 3 M S What design limits could be exceeded, in order to meet the K/A? Per Design Basis Document ME-260, the design limit of each RHR pump is 3800 gpm which is tested in the second part of the question. DBD ME-260 has been added to 3 F 2 X B S the references for the question. Also slightly changed the wording of Part 1 to incorporate the word design. This is not a comprehensive LOK question. Fixed as directed. LOD of 4 is too high, should be 2. Fixed as directed.

Would it be better to say there was no transfer to XST1? Stating the transfer was slow seems very subjective. At CPNPP Slow transfer is not a subjective term but a definitive term used in our procedures to identify when a bus will transfer and all downstream loads will deenergize and then be E brought back in a deliberate manner. The term 4 H 3 N S fast transfer is also used to identify a transfer in which downstream loads will not deenergize.

Added a reference to ABN-601 to show where the term slow transfer is used. Updated question to eliminate overlap concerns with question 15.

Removed references to XST1 and XST2.

Question now SAT Going solid to establish a bubble doesn't seem E like it would ever be preferred. We have a section 5 H 2 X B S in SOP-101A to fill the PRZR solid and then draw a bubble. We would use this method if a vacuum Rev. 11

(F/H) (1-5) Cues T/F Partial Minutia Focus Dist Link Units ward K/A Only was not drawn. Refer to SOP-101A, Section 5.6 for the alternate method. Where are the operation implications required to meet the K/A? The operational implication is that matching charging and letdown is required to either raise PRZR level or maintain level constant depending on the method used to draw a bubble. The procedure step doesn't reference adjusting let down so there isn't a true answer to the question. Step 5.5.2.B requires Letdown flow be established from RHR.

Swap distractors B and C. Fixed as directed Question now SAT I fail to see how a trip of SSWP 1-01 is plausible, especially since the cause of the low pressure could be, and likely is, an issue with SSWP-01.

Did not count as Unsat despite two implausible distractors, since it for one part of a two-part question Changed the second part of the question E to state that a trip of SSW Pump 1-02 and then 6 H 2 N S ask examinee if a Reactor Trip ONLY is required or a Reactor Trip and Trip of ALL RCPs is required. Reactor Trip ONLY is plausible because CCW Pump 1-02 is still running. With CCW Pump 1-02 still running is plausible to believe that RCP cooling remains intact.

Question now SAT 7 H 3 N S Does not meet the K/A, as nothing in the question deals with effects on RPS, only really recognizing if a TSLB indicator will light. We disagree. The TSLB is not just a light. It is an indication provided to alert the operator of the status of the Channels input to RPS (sensor or detector).

When a TSLB lights, it is showing the trip status of U the detector input to RPS. The TSLB lights are 8 H 2 X B S the only means the operator has to determine the status of RPS in the Control Room. The relay being tested is physically located within the input bay of RPS. Do any transmitters fail high when tripped by I&C? Don't they all usually go downscale?

I do not see in the provided reference material that the correct answer for part is necessarily intermediate range. It is obviously not narrow range, but why could it not be wide range?

10 F 4 M S ODA-407 does not specify an instrument to use.

Either Intermediate Range or Wide Range could be used but only intermediate range is provided as a choice.

This is Q11 from 2015 NRC exam, not noted on question history. Though it was used on a prior NRC exam, it is still listed as UNSAT because the bank question was written to an adequate K/A.

Does not meet K/A as there is nothing in the U question about predicting or monitoring changes 11 F 2 X B S in CS pump cooling. Simply asking cooling sources.

Fixed as 22 F 3 B S directed Question now SAT A is also correct because the question is not bound by time. Since thermal barrier return temperatures are increasing, 1HS-4691 and U 1HV-4709 will eventually close.

Fixed as directed Question now SAT LOD of 4 is too high, should be 3. Fixed as 24 F 3 B S directed Swap distractors C and D, making D the correct answer. Fixed as directed 25 H 2 B S Does not meet the K/A, as nothing in the question deals with effects on AFW pump, but reactor power. The stem stated that the TDAFW Pump MSL 4 steam supply valve indicated open. This was intended to be a failure of the valve in the open position. Changed wording to indicate valve had failed open. This results in the TDAFWP speed increasing which is the effect of the failure U of a component of the MRSS causing an AFW 26 H 4 X M S pump to start. Could argue that part 2 of the question in SRO-level of knowledge since it is testing depth of procedure. At CPNPP ROs are trained to treat this situation similar to an Initial Operator Action.

the question to better match the K/A.

Question now SAT It is not plausible to think MSIVs would remain open if you lost a condenser. Did not count as Unsat despite two implausible distractors, since it for one part of a two-part question. Disagree, CPNPP has other systems in place to protect the Main Condenser such as the C-9 interlock and the closing of the HP Stop Valves on the Turbine Trip.

E 37 F 5 B Remember that a Reactor Trip always causes a S

Turbine Trip, so when the reactor is tripped the turbine will trip and close the HP Stop Valves.

Also, the section for a loss of Main Condenser vacuum does not require the MSIVs to be closed lending even more plausibility that the MSIVs could remain open.

Question now SAT A could be argued as a correct answer since rising temperature could result in rising pressure, and vice versa. A better way to ask this question is to provide many CET temps, Th, Tc and RCS pressure values and ask what the SMM should E

38 F 2 B read. (See Wolf Creek 2017 exam question 59.)

S Better fit to the K/A. Added verbiage in Part 2 of the stem to assume that all other parameters will remain stable. This eliminates concern with A being a possible correct answer.

Not sure there is a correct answer. If you are stating in part 1 that you have lost instrument air, which results in the failure of TDAFWP speed controller, you have to acknowledge that you have lost the instrument air valves in the main feed system, and will have a total loss of main feedwater, and the reactor will have already E

Now asking emergency limit to save a life. I don't necessarily agree with 4000 mrem being plausible because it "used to be," since it has been 2000 mrem for at least 10 years. I will agree with the Rev. 11

This question is testing whether an SRO knows the reason why the Hi-3 actuation 77 H 2 N S logic has a unique configuration. There are many other examples of logic with 2 out of 4 coincidence (including the logic provided for Low PRZR pressure) that have both protection and control functions which makes it a plausible choice. Some other examples include MSL pressure, PRNIs, and N-16. This question meets Rev. 11

Question now SAT This is Question 89 from the 2017 NRC Exam (not noted on question history). The question is further flawed by the addition of "emergency air lock is not available." Therefore, if entry via outer door were not allowed, there would be now way to fix the inner door without going to mode 5, which is unreasonable. Slightly modified stem as well as what was being asked on Part 2 of the question to address this concern and the concerns with RO level noted below. Additionally, this question should not have been counted as E

80 F 3 B SRO level in 2017. The information allowing use S

of the door is a note in tech spec 3.6.2, which is above the line information. Additionally, I would expect any operator, licensed or not, to know requirements for an emergency containment entry. Slightly modified part 2 of the question to require knowledge specifically from the bases of TS 3.6.2 (and not contained in the RO knowledge area). Not an LOD 4 question. Question now marked as LOD=3. Not counted as UNSAT since this was an SRO question on a previous NRC exam.

There are no other weights in the TRM to come up with a 4th distractor. Just an FYI, this is all above the line TRM information, and since TRMs are treated the same as Tech Specs in the NUREG, I discussed with my peers 81 F 4 N S whether this should be RO level of knowledge.

We agreed that Tech Specs carry a different level of significance and decided ROs should not be expected to know TRMs from memory.

This is overall mitigative strategy, and thus RO level of knowledge. Disagree, the question is not asking if these procedures can be utilized to conduct a plant cooldown. The question is asking if under the given conditions provided, should the 83 F 2 X N S US use EOS-0.2A or ABN-803 to conduct the cooldown. This is specific information contained only within the body of ABN-803 (not contained in EOS-0.2A) and therefore is counted as knowledge only required by SROs.
