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 using a 1 B 5 (easy B difficult) rating scale (questions in the 2 B 4 range are acceptable).
- 3. Check the appropriate box if a psychometric flaw is identified:
The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
The stem or distractors contain cues (i.e., clues, specific determiners, phrasing, length, etc).
The answer choices are a collection of unrelated true/false statements.
The distractors are not credible; single implausible distractors should be repaired, more than one is unacceptable.
One or more distractors is (are) partially correct (e.g., if the applicant can make unstated assumptions that are not contradicted by stem).
- 4. Check the appropriate box if a job content error is identified:
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).
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).
The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).
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 that are designated SRO-only (K/A and license level mismatches are unacceptable).
- 6. Enter question source: (B)ank, (M)odified, or (N)ew. Check that (M)odified questions meet criteria of ES-401 Section D.2.f.
- 7. Based on the reviewer=s 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 AU@ ratings (e.g., how the Appendix B psychometric attributes are not being met).

B E/S B, 41.0, Stem describes the actions to take (K/A). Choices are which action is allowed? Distractors are actions not allowed. They are given, a soak is in progress, what action is not in accordance with a soak? Restructured to ask required action.
4 H
2 X
B U/S A, 41.8, Are the last 2 bullets in the stem required? The operators should know that phase B split out the CCW trains, does any procedure allow them (CCW Pumps)to be cross-connected? The nuggets to know here are: Train A RHR has no CCW cooling, but can be run if pumping water from the RWST. The last 3 responses each talk about RHR cross-tie, which have no affect and can be thrown out. There is only one reasonable answer. Might think about 2 of the responses being for Cntmt Spray operation. Revised Question.

U/S A, 41.8. K/A mismatch. CFR should be 41.5, This should be a generic question concerning RCP malfunctions. Restructured Question.

U/S B, 41.7, K/A mismatch. Does not deal with a loss of RHR system. Answer is obvious. I dont understand explanation of correct answer. What is the relationship between SI being reset or not. If valve is closed, same result. Replaced.

X N
E/S D, 41.7, K/A concerns controlling flow rates to components cooled by CCW. Multiple correct answers. C is a direct answer in the ALM. How much flow can go through the recirc line, is this realistic? Restructured Question.

X X
B U/S A, 41.7, Stem says heaters cannot be secured. It might be better to say without operator action. Response C and D are completely unrealistic. PORVs do not control pressure, only lower pressure uncontrollably. This is a repeat question from the last NRC exam (wording may have been slightly changed. This question not compatible with Question 34. Suggest replace this question. Replaced.

B E/S D, 41.7, What is the status of offsite power now, All heaters not on DG. What is source of control power (DC or 120 v AC)? Backup heater breakers will close if control power is available. Control Bank C must be closed from control board.
Where is locally, described in A and B? In containment? Explanation for group C heaters is misleading. It does not matter about a demand signal, closed from control room. A and C not credible. Revised.

Problem with third bullet. Stem has IR just at P6 setpoint. I believe SR counts would be lower (to allow P6 SR block to occur prior to SR RX trip)/ Revise Stem. Revised.

E/S C, 41.5, Take out all references to which pump is running, or will be started. It has nothing to do with the K/A, If the idea was to mimimize dose rates, then flow would probably be lowered to 45 GPM. Last bullet in stem should read Letdown is in service at 75 gpm. A and B responses should read Lower letdown flow to 45 gpm

If the reactor was at 100% power, then it would not be tripped. K/A mismatch To answer the question one needs to know the difference between train A and train B and the reactor is at power - nothing about major DC loads. Replaced.

M U/S Why would SGs become depleted? AFW flow is reduced initially due to excessive cooldown from depressurization. Once SGs blowdown, AFW flow is increased to stabilize RCS temperature. FRH is N/A, EOP -2 is also N/A. C and D not credible.

N E/S A, 41.3, The question is misleading; the alarm helps to identify the presence of leakage, not the amount. OPT-303 is used to identify the volume of leakage.
