ES-401 CN-2020-04 Written Examination Review Worksheet Form ES-401-9 Instructions
[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).The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
- 4. Check the appropriate box if a job content error 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).

Regarding use of the subject representation from simulator Thunderview mimic, images from simulator control panel mimics are often used in written questions at CNS to ensure consistent clarity. Sometimes brightness of actual panel photos varies due to simulator lighting or camera flash. This image was specifically reviewed for clarity when printed on white paper, as it will be during exam administration. Validators and reviewers agreed the status of the lights depicted on the image was clearly evident.
This question was validated by 14 validators and 3 Operations representatives, and none misinterpreted the intent of the image. This image is being retained in this question.
Regarding the setpoint 54 in the lesson plan, it is the TS allowable value. The sign is correct. CNS lists TS allowable values in lesson plans.

Modify stem to during a LOCA, complete the following:
Concerned that D part (2) could be argued correct, since scramming the reactor does limit the heat input to the RCS and thereby the energy that must be absorbed by primary ctmt.
kg - Modified stem to Regarding the reasons for a manual scram due to high drywell pressure during a LOCA, complete the following: per CE comment.
Regarding concern that D part 2 may be argued as correct, the stem asks for the reason stated in procedure 2.4PC for the scram action. The scram action is a manual action employed before the automatic initiation setpoint is reached. The distractor states the action is to avoid initiation of safety systems at the setpoint. It is assumed Drywell pressure will reach the initiation setpoint if it cannot be controlled below 1.5 psig by other mitigative strategies, such as by venting or by reducing power to reduce the heat input from Reactor Recirc pumps. Scramming would not avoid reaching the initiation setpoint (1.84 psig) of safety systems as stated in the Part 2 distractor.
Therefore, replaced part 2 distractor with To avoid automatic isolation of the Primary Containment vent pathway. The PC vent pathway employs valves PC-MO-231 and PC-AO-246. These valves isolate at 1.84 psig Drywell pressure. Scramming would not avoid isolation of the PC vent pathway.

The explanation does not track with the conditions in the stem of the question, specifically, JP LOOP FLOW NBI-FI-92A is 5 Mlbm/hr not 3 Mlbm/hr, AND Total Core Flow is 32 Mlbm/hr, NOT below 24 Mlbm/hr. Unsure if this question is valid given inconsistency between justification and actual question. Is this a New question as listed or is it a Modified question?
kg - This is a new question. The first version drafted was to test knowledge with core flow below 29.5 mlbm/hr, with <26 Mlbm/hr in the active Recirc loop. During validation, the question was changed to test knowledge with core flow above 29.5 mlbm/hr. The following sentence was inadvertently left in the correct answer explanation from the old version; Since indicated total core flow is below 24 Mlbm/hr, the 3 Mlbm/hr indicated for the idle jet pump loop is actually forward flow produced by natural circulation driving head.
So, removed that sentence from the correct answer explanation.

NRC 2015 45 What is the necessity of specifying 2 minutes for a grid UV in the stem? Many of the justifications seem to rely on recognition of time requirements for 1st level and 2nd level UV time delays, (5 sec, 7.5 sec), so it would appear to be make the distractors more plausible if the elapsed time was closer to these values.
kg - Per CE comment to reduce elapsed time in stem, changed time to 30 seconds, which accommodates 12.5 seconds for UV relays to trip plus 14 seconds (max. time per design) for DG to reach rated speed and voltage.)
ES-401 CN-2020-04 7
Form ES-401-9
_Rev 3 Page 7 of 16 OBDI 202 - IOLE Process Explanation discusses 5.5 seconds as the time delay for 2nd level UV, but the attached procedures describe 2nd level UV as a 7.5 sec +/- 0.8. Include the following excerpts in explanation:
1.1.1 There are two levels of undervoltage protection at CNS. The first level is a loss of voltage protection which is designed to actuate at conditions indicative of a grid voltage rapidly collapsing to zero volts (i.e., bus voltages < 2870V). Relays which actuate are a time undervoltage relay with inverse time characteristics (i.e., lower the voltage, the faster the actuation).
CNS Technical Specification setting for these relays is 2300V +/-
5% in < 5 seconds. This window sectionalizes an area of the inverse time relay curve which corresponds to the median of voltage levels tested during surveillance testing.
1.1.2 Second level of undervoltage protection is for sustained degraded (low) voltage conditions. This system is designed to respond to a static low voltage condition and will actuate whenever the bus voltage drops below 3880V +/- 52V for a time period of 7.5 +/- 0.8 seconds. This static setting is also the CNS Technical Specification setting.

In this case no stem or distractors have changed, but due to a procedural change, there is a new correct answer. I believe that the procedural change meets the intent of a stem change (i.e. the background information has changed), and that this question meets the intent/spirit of a modified question. Litmus test: If an applicant just reviews past 2 exams, and answers this question based on knowledge of the 2017 exam question, they will get it WRONG. It is in the NRCs and public interest that the facility test applicants on recent plant modifications, to include modifications to administrative practices kg - 8 of 14 validators missed this question due to obsolete knowledge.

S Im not enthusiastic about part (2) construction, as it isnt testing the expected knowledge in the most direct manner. Better to eliminate the 1925 line of the stem and for the question to ask, what is the LATEST time by which the NRC is required to be notified to satisfy reporting requirements? or some variation thereof.
This is not really testing on any knowledge of the Reactor Water Level Control System the stem is just telling the operator that something related to Reactor Water Level Control resulted in a required report to the NRC. As such, this question is written as a Tier III question. If the question gave the applicant a water level, or some aspect of RPV level control that required the applicant to determine the who/when/what/ of reporting requirements, that would meet the K/A.

-The way this question is structured is not really assessment based which would be expected for an SRO question. Reformat this question to include system parameters in the stem (DW pressure, RPV level, etc), and have the SRO assess conditions for procedure entry (which alone may not be SRO only if it is an AOP or major EOP), and select the appropriate mitigative strategy based on the plant conditions. Use the decision points you covered in your explanation of your answer and distracters as your guide.
Per CE comments, restructured question by providing plant conditions in stem, so the SRO must assess conditions and exercise detailed procedural knowledge in selecting the procedure containing mitigative steps and, also, assessing conditions required for performance of a procedural Critical Step.
[NRC] Given that Drywell pressure is 5.5 psig - well past the 1.84 psig setpoint that scrams the reactor, initiates core spray, SGT, isolations, etc., it is not credible that an applicant will not realize there are indications of a drywell leak. Provide indications that are not so extreme (pre-scram) that would still allow the applicant to diagnose need to fire squib valve. Change (is/is NOT) to (is/is NOT YET) for increased plausibility.
kg - The SRO knowledge being tested in Part 2 is not so much whether the examinee can discern whether a leak in the drywell exists, but whether the examinee knows specific detail of procedure content regarding exercising a conditional step. The examinee must know in order to direct firing the squib, a coolant leak must exist. An examinee may believe there are additional/other conditional requirements, such as indication of an offsite release above the Alert level, before squib actuation is
ES-401 CN-2020-04 12 Form ES-401-9
_Rev 3 Page 12 of 16 OBDI 202 - IOLE Process permitted, since that action is severe in that it destroys the TIP cable, is irreversible, and would be very complicated to repair. The test is not whether the examinee can determine a LOCA exists, but rather, given conditions that represent a LOCA exists, does the examinee know what to do with that information. It would be difficult to make the stem conditions below the 1.84 psig setpoint, since the TIP penetration would not be automatically isolated below the setpoint. Requiring the examinee to project in the future what should occur and trying to convey in the stem isolation does not occur might be confusing to the examinee.
[NRC] The questions justification for plausibility says The examinee who does [not]
realize there are indications of a reactor coolant leak in the drywell may choose this answer. It is not plausible given the conditions that an applicant wouldnt recognize a leak. If the intent is actually to test whether the applicant knows that a leak is a condition for firing a squib valve, then Id like something else in the stem to increase the plausibility that it is not yet required, such as a reactor water level still in the normal range (i.e. a small, slow leak), statement that no offsite release is currently in progress, etc.
kg - Added reactor water level is 30 inches, slowly rising to stem and enhanced part 2 distractor plausibility justification.
