ES-401 Facility: LaSalle
/Year: 2018 Written Examination Review Worksheet Form ES-401-9 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 (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 (i.e., 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, 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 stem).
- 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 that are designated SRO-only. (K/A and license-level mismatches are unacceptable).
- 6. Enter question source: (B)ank, (M)odified, or (N)ew. Verify that (M)odified questions meet criteria of 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).

River Bend 2010 (NRC Exam?)
NRC: Distractor B (Reactor Scram) is not plausible as the question stem indicates that the AC feed breaker specifically to the A RPS MG set trips causing a loss of a single RPS bus. If a scram were plausible under these conditions, there would not be a scenario where the RPS logic would generate a 1/2 scram condition.
The pedigree for Distractor A does not appear to address the correct information.
Distractor A concerns the reactor building ventilation system which would have one rad monitor channel fail downscale based on a loss of RPS A, and would therefore continue to operate. The distractor description appears to discuss RBCCW.
Response: Distracter B is plausible in that if both IN Compressors were lost eventually the Inboard MSIVs would drift closed due to a low IN pressure causing the Reactor to Scram on Reactor Pressure. However, this would take longer than 5 minutes to occur. Reworded distractor A for plausibility.

U NRC: Distractors A and C are not credible as they require the applicant to believe the RT system flow changes when then the flow indicator changing value is associated with the WR system. This can be identified in two ways based on the stem of the question. The EPN for the D/P gauge is 1PDI-WR028 and the question gives the cue specifically, the local RBCCW D/P gauge 1PDI-WR028.

NRC: Distractors A and C both include bus 243 at 0 volts with either the 2B HPCS DG running or not running. In either case, if bus 243 voltage goes below 75% the 2B DG will auto start and load immediately without implementing a 5-minute timer. In order for an answer to be correct with bus voltage at 0 Volts, additional faults, not indicated in the stem, would have to be assumed: That is, the bus had further degradation from the grid causing voltage to go to 0 and the 2B DG is faulted.

Therefore, just knowing you will not get a Scram gives you the correct answer. Considered an enhancement, because this is part of the free sample review.

E NRC: Correct answer B explanation (pedigree) must be corrected to indicate the plant conditions given in the stem. The explanation implies a leak in the room cooler.
The stem does not indicate an issue with the integrity of the room cooler, it indicates that the cooler fan has tripped on overcurrent.
Response: Incorporated NRC comments.

E NRC: No procedure is selected. Enhance the distractors by adding an appropriate procedural reference.
Response: During prep week, the SRO justification was updated. A question came up about LGA-MS-201 being complete may leave operators wondering what section was complete and the state of the MSIVs. The stem was updated to say LGA-MS-201 is in progress and that LGA-MS-201 Hardcard Actions have been completed. Hardcard actions defeat the MSIV isolation signals but do not deal with repositioning MSIVs.
NRC: Comments discussed and accepted.

NRC: The stem only asks for the first half of the information in each distractor and does not require any procedural course of action, only if the CRD pump needs to be secured and why.
Response: Rearranged stem so that the second part of the 2x2 incorporates a procedure and a plausible reason why that procedure was chosen. Both parts of information are required to answer the question.
NRC: Adding verbiage to stem regarding LGA-RD procedure attachments.

NRC: The stem indicates that MWe increased from 1190 to 1193, while reactor pressure increased from 1002 to 1004 psig and reactor power as indicated by the APRM increased from 98% to 98.3%. If there is an EHC fault and control valves modulate slightly closed, this will cause pressure to increase and therefore APRM power to increase as indicated, but MWe should decrease with the control valves more closed than where they started.
