ES401 PV202011 Written Examination Review Worksheet Form ES4019 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 to 5 (easy to difficult) rating scale (questions in the 2 to 4 range are acceptable).
- 3. Check the appropriate box if a psychometric flaw is identified:
- a. The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
- b. The stem or distractors contain cues (i.e., clues, specific determiners, phrasing, length, etc).
- c. The answer choices are a collection of unrelated true/false statements.
- d. The distractors are not credible; single implausible distractors should be repaired, more than one is unacceptable.
- e. 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:
- a. 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).
- b. 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).
- c. The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).
- d. 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?
Place the answer letter here Place the 55.41 or 55.43 item here
- 8. At a minimum, explain any Unsat ratings (e.g., how the Appendix B psychometric attributes are not being met).

There are also not enough "C" answers in the SRO portion (3).
Need to discuss why only one phase light causing a reactor trip plausible (A and C). In the entire 1 H 3 N S B 41.7 plant it seems like you need more than one of anything to generate a trip signal. Discussed/Q considered SAT Subcooling and superheat are two different things. Therefore, need to get subcooled out of the 2 H 2 X X N E C 41.14 stem since it doesn't match C or D. Discuss modifying distractors so all four are superheat.

ES401 PV202011 Written Examination Review Worksheet Form ES4019 As written, all four distractors are correct as they are all below 73%
3 H 3 X N U A 41.10 RWT level. Add "a MAXIMUM of" at end of stem.Revised/Q now SAT ON 2016 NRC EXAM. Change 4 F 2 X B E D 41.10 "will's" to "should's" in stem.
Revised/Q now SAT Need LOD. Change "will" to "should" in stem. First part of distractors could be confusing if 5 H 3 X X N E A 41.3 applicant thnks "lower" and "higher" refer to pitch. Better to use "more noise" and "less noise" than normal. Revised/Q now SAT 6 H 3 N S C 41.7 In B and D, change "event of accident" to "event of a design 7 F 3 X N E A 41.7 basis accident."Revised/Q now SAT Change "will's" to "should's" in stem.

Knowledge that a periphery control rod would have less of an effect on actual reactivity than 19 H 3 X X N U A 41.6 one near the center of the core doesn't appear to have much discriminating value (distractors C and D not plausible).Replaced/Q now SAT Change "will" to "should" in stem.
Doesn't seem likely that anyone would think pusle counters would be used over Reed switch indication. Discuss possible 20 H 3 X X N E A 41.6 enhancement alternatives.

B and D modified "isolate" to "restrict." /Q now SAT ON 2016 NRC EXAM. Student need only know the location and nothing else to correctly answer question. Not plausible that a 25 F 2 X B U D 41.11 contaiment area monitor would be detecting RCS activity better than an RCS monitor with no LOCA (distractors A and B).

Revised/Q now SAT Change "will's" to "should's" in stem. Possible two correct answers. It is not a "required" action to manually actuate CSAS on trend (should not shall), so if 33 F 2 X X N U C 41.7 the crew lets it auto actuate, that would be less preferred, but apparently not "wrong."

A and B not credible, as "any SM" too ambiguous (any qualified SM?) + if "any SM" was correct, 70 F 3 X X N U C 41.10 then the Unit 1 SM would also be correct. Also, need to discuss plausibility of "Salt River Project."
Restructured/Q now SAT 71 F 3 N S C 41.9 ON 2016 NRC EXAM. Does not appear to be a modified bank 72 F 2 B E B 41.12 question (looks like same question, but the answer has changed?)
