NRC: None. 2009 NRC Exam (Change Question Type to Bank vs. RO) 3 F 3 Y B S Response: Changed question type from RO to Bank.

Question is Sat.

NRC: None. 2006 NRC Exam (Change Question Type to Bank vs. RO)

Note: Good K/A match. How does the question tie to a procedural requirement for 4 H 3 Y B S system operation?

Response: Changed question type from RO to Bank. The procedure step that could be used for this condition is 1BwOA PRI-8, Step 8.d RNO Throttle 1CV121 and 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).

Question as written is Sat.

NRC: None. Need to see the ARP for Annunciator 1-1-A2. Done.

Note: Good K/A match.

5 H 3 Y N S Response: Added BwAR 1-1-A2 Rev. 16 to question technical reference.

Question is Sat.

NRC: How does this question address the K/A tie for Guidance actions contained in the EOP for Loss of CCW? (Not initially in the EOPs) The reason for the Rx Trip is to procedurally allow tripping of the RCPs without initiating an automatic RPS actuation.

N U Response: Revised the question to meet the K/A by changing the initial conditions to 6 H 2 N Y S place the crew in an EOP. Revised the question, changed 2 distractors and the answer explanations. Also revised the training objective and technical references to match the revised question.

Question is now Sat.

NRC: If the applicant is told the condition of the Rx each time following operation of the Rx Trip switches and is then asked to provide RTB position indication, how does that demonstrate an ability to operate and monitor the Rx Trip switches?

Good question, wrong K/A (057 AA2.03 might be better).

Response: One method to monitor the performance of a switch is to monitor the N E indications that result of the switch being manipulated. By recognizing the correct 7 H 2 Y indication response, the candidate is in fact monitoring the performance of the switch B S itself.

The alternate K/A suggested by the NRC does also match the question, however the APE 057 category has already been selected for use in group 1 tier 1 questions.

Chief examiner randomly selected an alternate K/A for this question, which provides a better Tier 1 question match and question was replaced with a bank question from the 2011 NRC exam. Replaced question is SAT.

NRC: FREE-LOOK. Modified from 2014 NRC Exam. Modify Distractor A to delete the word Remained to match other distractors.

8 H 3 Y M S Response: Changes made.

Question is Sat.

NRC: None.

11 F 2 Y B S Question is Sat.

NRC: Is there a procedural requirement to only monitor CC HX Outlet Temp from the MCR? Is local indication available and if so, why not use it?

Note: Good K/A match.

12 F 2 Y N S Response: BwOP RH-6, Placing RH System in Shutdown Cooling, contains a caution that reads Monitor 0TI-675 (T0622), U-0 CC HX Outlet Temp and/or_TI-674 (T0621), U-_ CC HX Outlet Temp as heat load is raised on the CC system.

This indication is available only in the MCR (not locally). Answer justification modified.

Question as written is Sat.

NRC: Use the same nomenclature from the stem information in the stem question.

(1SI8808A/B/C/D) 13 H 3 Y N S Response: Revised question stem using same nomenclature.

Question is Sat.

NRC: 2013 NRC Exam. The applicant must interpret the given indication and determine if any indication require a Rx Trip, therefore question is High Cog? Since F E this does not involve operator IAs, recommend removing immediate from the stem.

14 3 X Y B H S Response: Changed question cognitive level to high. Removed the word immediate from question stem.

Question is now Sat.

NRC: 2016 NRC Exam. Recommend moving the operator action statement from the E distractors to the stem question, since the stem question doesnt ask what to do.

15 H 3 Y B S Response: Moved operator action statement to stem as suggested.

Question is now Sat.

NRC: 2009 NRC Exam. None.

16 H 3 Y B S Question is Sat.

NRC: 2009 NRC Exam. None.

17 F 2 Y B S Question is Sat.

NRC: Is this required knowledge for ROs? (Why the action is taken and not just that the action is procedurally required?)

Response: The objective tied to this question APPRAISE each operator-initiated 18 F 3 Y B S recovery technique in its ability to restore the heat sink criticality function applies to both ROs and SROs. Generally, the ROs are required to know the reasons for procedural directed MCB actions.

Note: Good K/A match.

19 H 3 Y B S Response: Changed word alarm to annunciator Question is Sat.

NRC: (Ovation Mod results in different system response to the failed instrument than previous analog systems.)

Note: Good K/A match but may not directly tie to a procedural requirement.

E Response: 1BwOA INST-2, Attachment C, Pressurizer Level Channel Failure, has 20 F 3 Y N S the operator check if pressurizer level is maintaining normal level following a level instrument malfunction. If level is not normal, the procedural option still exists to take manual control. Procedure entry added to stem Initial conditions.

E 26 H 2 Y N Note: Good K/A match.

S Response: Made suggested changes.

Question is now Sat.

NRC: Which BwEP ES procedure does this tie to, 0.2 or 0.4?

Response: With the given stem information, the crew would currently be in 1BwEP ES-0.4. 1BwEP ES-0.2 was referenced in the answer explanation because it was the 27 H 3 Y B S procedure the crew transitioned from and contains the step monitoring for and diagnosing a reactor vessel steam void.

NRC: None.

28 H 2 Y N S Question is Sat.

NRC: None.

29 H 3 Y N S Question is Sat.

NRC: Is the stem focused enough to eliminate Distractor D also being a partially correct answer?

Response: Added the annunciator alarming in the stem to preclude the candidate E from assuming any manual action would have prevented the automatic action from 30 H 2 Y N S occurring. Also added the word INITIAL to the stem to eliminate distractor D from possibly being correct over time (i.e. if the VCT heated up and the water level expanded to the setpoint for diverting letdown to the HUT).

Question is now Sat.

NRC: None.

NRC: 2014 NRC Exam. Are the SACs considered to be part of the IA system?

Response: Braidwood does not have separate instrument air compressors. The SACs directly supply instrument air desiccant dryers that in turn supply the instrument air header and plant loads. Although Westinghouse designers gave separate system designators to the station air (SA) and instrument air (IA) supply systems, the 54 H 3 Y B S common practice by Braidwood training and many plant support groups is to combine the systems and treat them as a single system. For example, operator training materials are combined and designated as a single topic (Station Air and Instrument Air System).

Q# LOK LOD (F/H) (1-5) Stem Cues T/F Cred. Partial Job- Minutia #/ Back- Q= SRO B/M/N U/E/S Explanation Focus Dist. Link units ward K/A Only NRC: Are the ROs required to know that entry into 3.6.2 Cond C is required and that this will also require entry into 3.6.1 due to not meeting La requirements? Is this considered Immediate completion time TS action knowledge?

Response: ROs are required to know tech spec entry conditions. With the given stem conditions, a loss of containment integrity is indicated without having to analyze 55 H 2 Y B S a marginal leak rate (exceeding acceptable leak rate should be obvious). The completion time for TS 3.6.1, condition A is 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. However, the question is not asking the RO to apply the completion time, only know the TS entry is required. Exam facility rep. and validation team agreed that it was a reasonable question for an RO.

Since the information in the NOTES is RO knowledge, question as written is Sat.

NRC: 2016 NRC Exam. The stem question as written is confusing without looking at E the format of the distractor choices. (not stand alone) Attempt to reword the question.

59 H 3 Y B S Response: Revised question stem to clarify.

Question is now Sat.

NRC: It does not appear that Distractor D would be plausible for a novice trainee -

to believe that an alarm setpoint would be greater than the TS upper limit.

Response: Without giving the TS limit nor the alarm setpoint in the question stem, the distractor remains plausible. The distractor is a natural progression of the previous answers (+ 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />). Additionally, there are several other containment 60 H 3 Y N S pressure alarms that are all above the Tech Spec pressure limit (SI, MSI, CS). Also, an example of another system initial pressure alarm that is outside the Tech Spec limit: 1-12-C1, PZR PRESS CONT DEV LOW is the initial alarm on dropping pressurizer pressure. Setpoint at 2205 psig which is below the Tech Spec DNB limit of 2209 psig.

Question as written is Sat.

NRC: Reference Provided in stem. Modified from 2016 NRC Exam RS20033-N02.

Although an additional IC was added, the original part 1 of the answer is unchanged.

Response: Agree, Part 1 answer remains the same. Question was modified by 61 F 3 Y M S adding 2nd part of answer (whether SFP level remained above or below Tech Spec limit).

NRC: How is this SRO-Only and why is this High Cog? For the specific question asked in the stem, the question should be able to be answered using only system knowledge of CIS to assess Containment isolation.

Response: The question is SRO ONLY because it requires detailed emergency procedure knowledge (1BwEP-0, step 8 RNO action to locally close valves that are 82 H 2 Y Y N S outside containment) which is beyond the overall mitigation strategy. If the NRC interprets the stem statement The SRO then directs the RO to perform and/or dispatch EOs to perform the step 8 RNO actions as a cue, then the statement can be revised to read The SRO then directs the step 8 RNO actions to be performed.

This would eliminate the possible cue that field actions are required in the RNO action.

The BwAR subsequent operator action to CONSULT RETS 2.1-1a is an administrative action that would be performed by the SRO. Administrative Action Requirements (AAR) are initiated and completed by SROs. It would not be expected that a RO would have knowledge of AAR content.

The BwAR does not give any specific information as to why the AAR is consulted nor does the BwAR reference any information regarding bypassing the rad monitor interlock function. All that information is contained within the AAR only. In this context, the selection of a procedure to mitigate effects of the event (the SRO justification) is comparable to a procedure transition step from an AOP or EOP during any other plant event.

Step 1 in BwFR-H.1 evaluates whether a heat sink is required for current plant conditions. If not, the RNO returns the crew to previous procedure and step in effect with no actions taken. This step is not contained in the OAS nor the CAS and is therefore SRO ONLY required knowledge.
