General Comment for all Questions: 1) List justification statements in order of how they appear in question; 2) Provide KIA statement along with KIA number to save man hours for reviewers to look up in KIA catalogue; 3) List reason why each distractor is plausible but incorrect it saves time reviewing and saves man hours in addition helps developer to ensure distracters are adequate.
How many licensed SRO and ROs validated this exam? Initaliy 2 SROs and 2 ROs and then later after revisions were made revalidated with lSRO and 1RO. Did you pre-brief the validators to make sure the distracters were plausible but incorrect?

[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 - 5 (easy - difficult) rating scale (questions in the 2 - 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 truelfalse 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 (Le., the question has a valid KIA 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 (Le., it is not required to be known from memory).
The question contains data wlth 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 KIA and those that are designated SRO-only (KIA 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?

19 F 2 N E 0191) This 0 needs work. The question is what actions per E-5 are required, but the reference given to the student is S32.3.A The correct answer is step 3.11 of E-5 which I do not think an RO needs to know from memory. 2) Do you have an RO LO that requires this knowledge from memory?

26 F 2 X N E 0 1) Confused by stem "when selected
... indicates both control rods are moving slower than normal" ? 2) Are you implying that both rods are drifting out of the core? 3) The stem is not procedurally correct. With a rod drift alarm you would not press the rod drift reset. You would select that rod. The whole first section of the stem could be eliminated. It just confuses the situation.
Per the procedure step 2.2 if 2 rods are drifting out scram the reactor. Not dependant on reactor power. Stem simplified and focused. Actual rod numbers added to the stem.

With recirc running there is forced circulation. The caution at step 3.0 says level must be greater than 60 inches(assuming upset level is LI-42-R605) to credit natural circulation as an alternative method of reactor coolant circulation. Add to stem No Recirc pumps running for clarification.

3).May need to add one more electrical failure to get down to get down to one remaining pump so that distracters are more plausible .
- 4) The stem says the CRS has ordered vessel depressurization, therefore he is past the decision point about how many systems and pumps are running. .
He should be entering T -112 and performing concurrently. The answer that ED cannot proceed is out of place. The decision has already been made to do it. Recommend remove that statement from the stem

The answer is a direct look up on the provided reference T-116 step RF-14. When 5 SRVs are open and RPV press is below 230 psig then continue. The next step is to slowly commence injecting. Modified Stem from stating loss of level indication, to including indications that must be used to diagnose. Changed Distracters to support answers where it is determined level is known. Added T-117 as a reference 78 H 2 X B E Q 78 - SRO Q3. Distractor D is not plausible because the TRM does not require a continuous fire watch.
Recommend 14 day LCO and then an hourly fire watch. Distractor C has a typo, should be lowered to 200psig. Distractor d has a typo. Should be watch instead of water. Also explanation d for D has the same typo. Comments incorporated.
79 H 3 X X N U Q 79 - SRO Q4. Technically Answer Band D are also correct. Narrow range 1R606C is +5 inches which is greater than MIL +3. Therefore per step 4.1 narrow range is usable. This would make Band D correct. The stem should not have RPV level is -100". The question writer used this fact to determine which instruments are usable. Where in a real situation the SRO would not know exactly what reactor level is and would need to determine which instruments are usable.

83 H 3 B E Q 83 - SRO 0.8 The question asks what action is required. The alarm response directs the operator to "consider". The wording should be improved.

Licensee Submitted Exam to NRC COB 8/20. NRC started review 8/23/10
27 July 2010 Review Comments for T-75 Day Limerick Exam Outline Submittal The exam outline was hand delivered to the Regional office on Tuesday, 7/20 and comments were provided per telecom on 7/27/10. The outline was developed using a BWR Owners Group Random Generator software. The audit exam is being developed independently by a different staff person in a separate area with no communications in so far as the written exam. The NRC operating tests were developed with no overlap with the topics planned for the audit exam.
Scenarios The scenario outlines are all new. Requested that narratives be provided next week which include the proposed Critical Tasks for each of the scenarios.
Admin JPMs RO topic Shift Turnover Checklist will be designed for classroom administration - change "S" to uRn on outline.
RO topic to Activate Site Evacuation is planned for HI Rad situation with announcement suggested to include activation of emergency organization also SRO topic Shift Turnover Checklist A.1.1 will be designed for classroom administration change "S" to uRn on outline. This will include TS implications SRO topic Pre Control Rod Withdrawal Checks will also include TS implications.
Simulator JPMs Three proposed alt path JPMs involve securing equip due to hi vibs (b) or hi temp (c & e) and in addition only one new and one modified JPM which is at the minimum the rest from the bank suggested replacing RCIC JPM with a new alt path JPMs.
In addition, for the 5 JPMs designated for SROUs 2 of the 5 were from the last 2008 NRC exam.
Suggested replacing a or g.
Written SRO Outline The following KIA question topics did not appear to be SRO level topics: 1, 2, 3, 6, 8, 9, 10, 13, 14,17,94,95,98,96.
Written RO Outline Cautioned not to write questions involving simply asking what the power supplies are to a component directly ex. air compressors.
Limerick Operating Exam Review Comments Scenarios General Comments:
- 1. All required operator actions are required to be scripted for each event (Le., all switch manipulations, etc). Note: Verifications need not be scripted.
- 2. List required operator actions chronologically as they would be performed e.g. following a SCRAM the RO should report if all rods are not full in and start taking actions to insert these rods as appropriate.
- 3. For all CTs please consult NUREG 1021, Appendix 0, Simulator Test Guidelines, section 0.1 and list how each of the 4 criteria are being met for each CT (Le., safety significance, cuing, measurable performance indicators and performance feedback also failure criteria) in some cases I don't believe your listed CTs meet the criteria for safety significance.
- 4. Please highlight CTs and operator actions taken to respond and mitigate for each CT in the body of the script.
- 5. Please script in at the end of each scenario to the have the applicant in the role of CRS classify the event - please add the expected classification to the scripting.
- 6. In the body of the scenario guide please list the procedure title the first time it is referenced in each scenario e.g. T-213, 215, 216, 212, 221, 117, 270.
- 7. At the top of each event page please summarize expected failures- not required but helpful.
- 8. The scenarios overall lack diversity in that they short on both instrument failures and electrical failures that cause an integrated or dynamic plant challenge e.g. loss of safety busses or loss of off- site power.
- 9. Please enhance scenario summaries in front of scenario guides. Not required but it helps when reviewing the scenario just prior to administration. Typically scenarios have a narrative overview or executive summary towards the front of the scenario.
- 10. What is the origin of these scenarios are they new and or significantly modified?
- 11. Scenario 1, 3, 5 all involve a LOCA and exceeding PSP scenario appear to lack diversity e.g. no hi rad, fuel failure, offsite release or Loss of offsite power etc. Recommend replacing scenario #1 multiple EOP legs are not challenged and LOCA theme repeated on 3 of 5 scenarios.
- 1. Event 3 - list how much power is required to be reduced and how power would be expected to be reduced with just recirc or rods and recirc. Additionally, what is the plant response to this failure? Does the EHC backup regulator take control, and if so how much of a transient is it?
- 2. Event 3 - Is there a procedure that addresses EHC failures? Also the event describes maintaining pressure below 1053psig. Is there any chance a crew would fail to do this and the unit scrams. If that happened the next 3 component failures would be missed.
Might be better to have some of the single component failures done prior to this event if
there is a chance of a crew not being able to control pressure or choosing to manually scram to be conservative.
- 3. Event 3 - list what ARCs
- 4. Event 4 - RECW pump trips and start standby pump. Event 6 also CRD pump trips and start standby pump events should be more diversified. How about an instrument failure to replace on these malfunctions - e.x. RPV level controlling channel fails low so that affects FW control?
- 5. Event 5 - List all required operator actions for RO and BOP - no required actions to stabilize then no credit.
- 6. Event 6 - If sprays are still available, why will the plant exceed PSP? If PSP is not exceeded, then the crews will not ED and the second critical task will not be performed. The scenario would then only have one critical task and need 2 minimum.
- 7. Event 7 - Bold and highlight the critical tasks and the required operator actions to mitigate each CT.
B. Event 7 - List the critieria for spraying the DW and the valves that are opened. List the values when the PCP curve cannot be maintained and SE-10 actions.
- 9. Event 7 - D-1 looks like a LBLOCA not small break LOCA? Critical Tasks- The first critical task should not be before exceeding 340 degrees or 55 psig. Procedurally when suppression pool exceeds 7.5 psig. SP spray is required. The second critical task should also not be dependent on 55 psig. Suggest the criteria be if they exceed PSP for 3 minutes and have not taken actions to ED then they would not meet the critical task. Are you sure that you will have to ED, if the crew aggressively reduces pressure early on?
- 10. Simulator setup section. Do not see a failure for EHC pressure set.
Scenario # 2 (ATW 19%)
- 1. When was the last time Limerick administered a low power scenario 3-5% for an initial license exam? This scenario at 19% is not considered low power. We should have one low power scenario every other exam and we did not have on the last exam Oct OB.
- 2. The scenario does not have a D-1 outline form on the first page of it
- 3. Event 2 - would want to pull a handful of rods enough to demonstrate effective reactivity controls 5% change in Rx power.
- 4. Event 3 - List operator actions any back panel actions required?
- 5. Event 4- List all required RO and BOP actions? Are there any other actions required other than initiate CR HVAC chlorine isolation manually. If not need an electrical loss that involves integrated plant response and corrective actions. In scenario summary it states "once action for drifting rod is complete ... " I see no other reference to a drifitng rod on D-1 or in scenario guide.
- 6. Event 5 - Trip of both Recirc pumps - if this results in an auto P/F scram it would not count as a separate malfunction just a setup item for the major event ATWS? Even if not an auto scram (only at 19% power), the only actions are to scram the reactor which is unsuccessful. So I believe it should not count as a separate malfunction. It is set-up item for the ATWS. You need to evaluate if an additional malfunction should be added.
- 7. Event 6 -Implement TAR - define?
- 8. Event 6 - Bold and highlight the critical tasks and the required operator actions to mitigate each CT.
- 9. Event 6 - List all of the expected operator actions taken for T-213, 215, 216,212,221, 117, 270 in the body of the script and also list the procedure title the first time it is referenced in the script.
- 10. Event 6 - Script expected actions to lower level.
- 11. Event 7 - failure of RDCS is this a call out to the field?
- 12. Event 8 - turbine byp. valves fail use SRVs to control pressure. Note: Page 4 indicates that this malfunction will not be entered until after power is intentionally lowered making this malfunction meaningless - hands in the pocket. This event needs to be triggered when the A TWS is first initiated to make the event meaningful.
- 13. Critical task #1. This needs to be expanded. Is T-215 giving direction to electrically scram the reactor by denergizing RPS. Be specific in specifying what required and success criteria.
- 14. Critical task #2- What power will the plant be at after the recirc pump trip? If below 4%
(APRM downscales), then no need to lower level. And therefore task is not critical.
- 15. In section on malfunction/remote function/report for event 6, 7 and 8 there needs to be coordination. Event 6 says when level is lowered pull the scram fuses, event 7 when terminate and prevent is complete reset RDCS, which is only a minute or 2 before 50inches, and event 8 is at -25 inches. If the reactor scrams at -50 inches there will be almost no time to respond to drive rods or to control pressure with SRV's. Events 7 & 8 RCDS should be reset earlier to provide time to drive rods should occur earlier and turbine bypass valves should fail earlier before pulling scram fuses.
Scenario #3 (LOCA, 3 rods, PSP)
- 1. Event 1 - appears to be of little value
- 3. Event 3 - List procedure titles the first time referenced for all procedures entered e.x OT-101, GP8.5, On-113.
- 5. Event 4 - List steps take to reduce power. How much is power expected to be reduced.
- 6. Event 5 - It doesn't look like any creditable BOP actions required -- list all required operator actions.
- 7. Event 6 -- Event Description at top of page summarize that happens HPCI aux oil pump failure, loss of condensate/FW. Should list condensate pumps tripping in script.
List all required RO & BOP actions T101, T102, GP8.5, T-225, T-117, T240, SE-10.
Did not see a step to enter T -117 for ATWS. Also states enter T -112 when level drops to -161. T-117 Can level be restored and maintained above -186, if answer no then ED per T-112.
- 8. Event 7 - pg 18 recognize failure of 3 rods to scram should be listed chronologically as event occurs on page 16 when RO scrams reactor.
- 9. Event 8 - 012 failed to start what is the safety significance of this failure at this time if no operator actions taken - doesn't appear to affect the success path of the scenario?
- 10. Critical task 1 not sure of the safety significance of not performing this CT in a timely manner? List 4 factors for CT.
- 11. Critical task #3, not sure if spraying drywell after ED would meet definition of critical.
The max energy of the reactor has been transferred to the containment. Pressure will not exceed 55 psig.
- 12. LOCA via "1 a" Recirc is the same LOCA as scenario #1. In scenario 1 the setting on small LOCA is 50%, In this scenario it is 45% and a 1% large LOCA.
Scenario #4 (Steam leak, ATWS - ARI works)
- 1. Event 1 - list open inbd MSIM and scenario guide top of pg 10,11 show open outbd MSIVtypo?
- 2. Event 2 & 3 - would like to see ROs drive rods how much do we expect to decrease power for reactivity.
- 3. Event 4 - Trip TECW pump cook book limited testing of operating knowledge. Would prefer integrated plant electrical fault to add depth and diversity to exam or at least an instrument malfunction that initiates a transient of some sort requiring the crew to take actions to stabilize for BOP.
- 4. Event 6 - please list all required operator actions for T290 and 291 with procedure titles.
- 5. Event 7 - please move actions to place actions in chronological sequence on pg 17 after placing mode switch to sid.
- 6. Event 8 - Don't understand consequence of failure? What do the operators have to do different? List required operator actions to respond to failure.
- 7. Event 8 & 9 - List actions in chronological sequence e.g. Event 9 actions should be moved to bottom of pg 17 and top of 18 when 5 ADS valves are opened.
- 8. CT1 - don't understand what makes T-290 actions critical. Please list 4 factors qualifying this as a CT. Can we monitor secondary plant temps in the CR on SPDS or on panels?
Scenario #5 (LOCA, steam leak can't be isolated, PSP)
- 1. This scenario is similar to scenario 1 LOCA but is more challenging due to the failure of the ability to spray the OW.
- 2. No instrument failures in this scenario.
- 3. Event 3 - please list all required operator actions to decrease power per OT-104.
- 4. Event 4 - please list all required operator actions SE-10.
- 5. Event 5 - please list all required operator actions -list RWCU affected valves.
- 6. Event 6 same as scenario 1 and 3.
- 7. Event 7 & 8 - OW sprays place in chronological order before ED.
- 8. Critical Task #3. If OW sprays are unsuccessful causing to exceed PSP, then the OW sprays should not be a critical task. Even if the crew eventually gets to RHR service water to spray, if it is after the ED then not critical.
- 9. Critical Task # 2. Same as previous comment. Should not be based on 55 psig. Should be based on exceeding PSP.
General comment: Try to decide before Tuesday if any of the simulator JPMs can be performed in parallel (2 or 3 at a time) during exam week. You need to consider: if simulator setups are similar enough, proximity to other JPM(s) being performed in parallel and especially on faulted JPMs if they are going to cue the other applicant(s) that are in the simulator at the same time.
Simulator/In-plant JPMs
- a. Ok
- b. Only 2 critical steps marked in this JPM. There may be other critical task not marked. Step 9b lower speed - it looks like your intent that this doesn't resolve the problem and you need to secure the machine - please clarify.
- c. Ok
- d. Opening N2 makeup valve for 5 seconds does not test operator understanding and safety significance of task is marginal at best. Recommend replacing JPM with something that involves venting the DW due to high H2 orsomething safety significant.
- e. Do we have an EDG overhead alarm in the CR that would accomplish the same purpose e.g. low lube oil or bus fault rather than having to call out to the field?
- f. All the rest of the JPMs appear to be Ok.
RO Admin ..IPMs A.1.1 - Borderline LOD - does this really need to be done in the simulator. It will tie up too much simulator time. Please provide screen shots or whatever to facilitate performing in a classroom.
A.1.2 - non assigned A.2 - Steps 2 and 5 clarify which pages affected and provide a key.
A.3 - provide a key.
A.4 - Replace ..IPM. This is technically not a license level operator task - anyone could be assigned do make the announcement, also low LOD and it wastes simulator time and slows down and stretches out the exam unnecessarily. Replace with a second conduct of operations task designed for classroom administration.
SRO Admin ..IPMs A.1.1 - Borderline LOD - does this really need to be done in the simulator?
A.1.2 - Replace JPM - not license level task to review quais of equipment operators also low LOD - NRC does not regulate these activities. Recommend replacing with JPM to test work hour rules and or licensed operators quais covered by 10 CRR 55.
A.2 - initiating cue too leading - just review it - don't have to say for errors and TS concerns that should be obvious. Also after step 7 should list task standard summarize expectations.
A.3 - provide a key. Is anything wrong with the release if nothing wrong then nothing to evaluate?
AA - provide a key for notification form.
