ES-401 Facility: Clinton Year: 2019 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).

Clinton NRC ILT 12-1 Exam NRC: If the applicant correctly assesses that having the steam line plugs being installed negates method 1 as a viable option for recovering shutdown cooling, they are able to answer the question without requiring any additional knowledge regarding methods 2 and 3. Distractors A, C, and D all include method 1 as part of the solution.
Recommend a distractor that lists methods 2 and 3 only. [Question as submitted would have been UNSAT, but since question was a previously used bank question, the question rated as an ENHANCEMENT]
Facility Response: Changed distractor D to read Methods 2 and 3 ONLY and revised answer explanation accordingly.

References provided: Main Control Board images Clinton NRC ILT 14-1 Exam NRC: Is two minutes after the scram a long enough time that the novice operator will be able to assess that LLS SRVs D and C will have fully cycled open and then shut having lowered pressure to 926/936psig and then have pressure rise to the lower opening setpoint of SRV D where it is now again lowering on that one SRV?
Specifically, is it possible that an applicant can argue that distractor A is correct and that pressure is still lowering to 926/936 on SRVs D and C?
Facility Response: At T=2 minutes, it is not feasible for two SRVs to be open. The sequence of events is as follows:
T0 = Group 1 Isolation / Reactor Scram / 51D and C open T0 + 10 seconds - 51C closes, 51D remains open 51D will then cycle at the LLS setpoints from that point on.

NRC: The question is too easy because an MSIV closure results in a reactor scram, which is basic knowledge, and without an ATWS, the APRMs will indicate 0% power.
Facility Response: The facility contends that the question is not unsat as written. At CPS, MSIV closure only results in a reactor scram if MSIVs in two different Main Steam Lines close with the Mode Switch in RUN. The question requires a diagnosis of plant conditions in the stem and a knowledge of RPS logic to answer correctly, and is thus > LOD1.
Final Resolution: Question SAT as is; no changes were made.

NRC: 1) The pedigree is unclear that Shutdown Criteria of CPS 4100.01 is met with 3 control rods at position 02. According to CPS 4100.01 Shutdown Criteria is:
- All rods are full in at 00, OR
- No more than 1 rod out at position 02 or beyond, with all other rods in at 00 OR
- A qualified Reactor Engineer has determined that the reactor will remain shutdown under all conditions without boron
Facility Response: EOP-1 requires EOP-1A to be entered if shutdown criteria is not met after placing the RMS in shutdown, which is the case in the stem. Shutdown criteria is only met after manual scram and ARI have been initiated. Therefore, entry into EOP-1A is required.

NRC: It is very clear from stem conditions that conditions exist that will expose personnel to radiation. In a 2X2 format, this results in 2 implausible distractors.
Facility Response: The site contends that distracters C1 and D1 are plausible for the reasons provided in the answer explanations. Certain leaks in the FC system are isolated from the MCR while others must be performed locally. The candidate has to diagnose the leak location with the information provided in the stem to determine the leak isolation method. Revised the question as follows:
In the stem, added that rad levels outside the Fuel Building are normal.
In the stem, changed the first part to ask if the leak could be isolated from the MCR.
Updated the pedigree - Choice B is now the correct answer Final Resolution: Question SAT following changes.

In addition, the attached reference material does not include information on the status of 1SA033 manual valve which will affect the IA header conditions in the fuel handling building.
Facility Response: The facility contends that the question is sat as written. The stem parameters are adequate to diagnose the leak location and were technically validated by the facility validation team. CPS 3214.01 Figure 1 follows the convention of the M05 mechanical prints at CPS, where a hollow valve symbol indicates the valve is normally open.

Why would containment spray be manually initiated? Per CPS 3312.01 note 8.1.6, High DW pressure (1.68 psig) must be present before containment spray can be manually initiated.
Facility Response: The facility contends that the question as written is not psychometrically flawed with respect to stem focus.

NRC: Distractor B does not appear to be reasonably eliminated without additional information from TS 3.8.6. Are the applicants expected to know, from memory, the parameters/values that would constitute battery inoperability? This does not appear to be the case according to learning objective 263000.12.
Facility Response: The facility contends that the question is valid as written based on validation data, and the knowledge needed to answer the question. Battery design voltage is required knowledge. This value is tied to B3.8.4 and 263000.1.1.
In addition, the specific battery parameters listed in 3.8.6 are not required to be memorized because those parameters are applicable when the battery charger is supplying float voltage to the battery, which is not the case in this question. Clarified the answer explanation for distractor B and D.
Final Resolution: Question SAT as submitted; changes made to answer explanation only. [Regarding the explanation for the correct answer, stem conditions simply indicate that the battery charger is not supplying the bus but not why.]

Clarified Distractor A explanation to discuss the use of Level Bands B and C.
- 3)
Distractor C is an incorrect answer. EOP-6 Suppression Pool Temperature Leg states that if suppression pool temperature cannot be held below Fig P, Heat Capacity Limit, then lower pressure to stay below the limit. Since this action has not yet been performed (RPV pressure at 950 psig cycling on the SRVs), the next required action is to lower pressure to stay the limit.
A blowdown would not be appropriate unless attempts at reducing reactor pressure failed to control suppression pool temperature and RPV pressure below HCTL. Clarified distracter C explanation.
The facility contends the question is sat as written.
Final Resolution: Question SAT as submitted; changes (clarifications) made to answer explanation only.

S Reference provided: Embedded Table NRC: Why arent the Area Radiation Limits provided as an attached reference instead of an embedded reference? As provided, the question spans 2 pages, with the stem of the question on the 2nd page. This seems awkward and confusing.
Facility Response: The interpretation of what constitutes a reference has changed since the last exam project. In the past, only external references were counted.
Additionally, the table is contained on an EOP flowchart, making it difficult to add as an external reference. The validation team had no issues with the readability of the question.

S NRC: Mode 1 being given in the stem is unnecessary, as the applicant should be able to deduce the Mode from the given 18% RTP. (See Q80, Rx power was given at 35% with no Mode given).
Facility Response: Changed the first sentence to read, The plant is operating at 18% power.
Final Resolution: Question was SAT as submitted; however, the facility made the recommended change.

S References provided: Main Control Board image & Attached TS Information NRC: 1) In the provided reference LCO 3.6.4.3, what purpose does redacting the Completion times in Condition C serve? While the completion times are immediate, these actions are not in the answer or distractors of the question.
- 2) Since the flow is not banded on the provided MCR indication reference, is the 3600-4000 cfm TS requirement value required to be known from memory? It appears its not listed in the TS surveillance requirements nor does it appear in the bases. Surveillance acceptance criteria only?
Facility Response:
- 1)
It has been our common practice to redact any 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or less completion time statements for consistency.
- 2)
The design flow is listed as surveillance acceptance criteria in 9067.03 and is tied to N-CL-OPS-261000.1.5.1 and ITS 5.5.7d. Validated as fair and operationally valid.

Provided Reference NRC: Providing survey values around 1RIX-AR035 would provide more operational validity to distractor C than stating normal values. Distractor C is much more easily eliminated by essentially providing in the stem that the cause was a spike, which makes an Alert declaration not plausible.
Facility Response: Changed the stem to read, RP survey in the vicinity of 1RIX-AR035 is reading 0.1 mrem/hr.
