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 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 (e.g., 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, and 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 the stem).The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
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 K/As that are designated SRO-only. (K/A and license-level mismatches are unacceptable.)
6. Enter questions source: (B)ank, (M)odified, or (N)ew. Verify that (M)odified questions meet the criteria of Form 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). _Rev 3 Page 1 of 20 OBDI 202 - IOLE Process

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 We determine NR or WR by the units % or inches. QID 62 of this exam specifically ask for this knowledge so we did not add NR or WR to this QID as it would potentially answer QID #62.

If youre going to use a safety function as a distractor, it makes more sense to use CORE HEAT REMOVAL, which has a closer nexus to RCS Heat removal, but is still wrong. RCS Pressure Control is not a very credible distractor based on S/G level.

The team made a decision to NOT use a safety function as a distractor but use EFW interposing relays for the distractor instead. SEE Rev 1 of QID and explanations.

All Rev. 1 changes accepted by the NRC on 2/4/21 phone call.

6 H 3 N S Part 1 is asking what the latest time Reactor must be tripped and RCPs stopped if CCW is not restored, so rephrase to: (1) What is the latest time by which the reactor must be tripped and RCPs stopped, if CCW is not restored? (1005 vs 1010).

Rephrased this QID as requested above.

Part 2 add Per AOP 2203.025 Technical Guide, to tie it to an explicit procedure.

Reworded to state Per the RCP Emergencies AOP 2203.026, Also, request that you confirm this is expected RO knowledge per ANO2 accredited ILT program, since EOP/AOP bases are typically considered SRO knowledge.

E We hold SROs to the CEN 152 Basis for EOP steps along with the Technical Guides 7 H 3 X N S Basis we have developed here at ANO Unit 2. We also have Lesson Plan RO/SRO objectives and teach the ROs the steps of all AOP/EOPs and the basic reasons for the step per the Tech Guides/STMs/Procedure Notes & Caution. In this QID the reason is also listed in the CCW STM 2.53 which is now in the explanations for this QID.

Added the following Statement to the explanation to Answer A based on feedback from the NRC on 2/4/21 phone call: The reasons/basis for steps in the AOPs and EOPs are covered by RO/SRO objectives and are taught in the ANO Unit 2 ILT Training Program.

Link units ward K/A Only Is a 100 psig pressure band the standard range the CRS is expected to give? I dont want someone to argue that the given correct answer, 1025 to 1125 psig, is not actually optimal because there is some reason 1125 shouldnt be the top of the range. I agree 1025 is the optimal bottom.

Revised Part 2 of this QID to say To keep RCPs running per the CRS directions, RCS pressure should be lowered to a MINIMUM of ___ and deleted optimum 10 H 3 N S Bands Changed all distractors/answer to a single pressure. Also raised Temp to 518/SAT Pressure for easier use of the steam table.

In Revision 2, changed the question to only have two pressures (correct one and the most plausible other one) turning the question into a 2 x 2 QID based on feedback from the NRC on 2/4/21 phone call.

NRC OK.

11 H 3 N S Part 1: I dont see how testing on whether ESFAS is initiated from the normal control board location, or a backup location in a locked room is credible or discriminatory.

Why would an applicant think they would not actuate it from the normal location in this question? Consider testing on application of RNO actions of step 15.E.RNO for aligning HPSI pumps, if one of the 4160V vital buses is not energized from offsite power. Or, the overall steps required to align OTC.

E Replaced Part 1 with Part 2 and added new step for Part 2 to test on the overall steps 12 H 3 X N to align OTC per the LOF EOP.

S In Revision 2, changed the Part 2 step top state Step 15 will require the crew to ENSURE ALL available Charging pumps running AND ENSURE at LEAST

____(2)____ HPSI pumps are running based on feedback from the NRC on 2/4/21 phone call.

Nrc ok 13 H 3 N S M-NRC 2006 Part 1: not enthusiastic about testing on whether applicant knows which bus is red train and which bus is green train. Would rather test on whether applicant knows if E inverter must be deenergized in 1 hr or 2 hrs (step 16 vs 17).

14 F 2 X M S Rephrased this QID as requested above.

Part 2 is not very credible that an applicant would think an inverter is being deenergized in order to reduce load on an EDG vice Battery. Prefer that this question test on whether applicant knows if the vital 120VAC bus will be ENERGIZED _Rev 3 Page 3 of 20 OBDI 202 - IOLE Process

Rephrased this QID as requested above; however, at the completion of Step 17 actions, the vital 120 VAC 2RS3 bus will still be De-energized as the Alternate Source of Power comes from 2B54 which is powered from 2B5 which has no power per the conditions in the stem.

REFERENCE PROVIDED The directive to suspend fuel and control component handling activities is FIRST given immediately upon entry into procedure 2202.002, in step 2, not in step 9.

You are correct.

Part 1 is not very discriminatory that CEA handling evolutions would be allowed to E continue given it is the first operational directive given in the procedure. Id prefer 16 H 3 X X N S that this question test on the log-taking requirements of step 1, Commence performance of Attachment D, SFP Level and Temperature Log. Test on whether logs must initially be taken every 30 minutes (correct) or hourly. This is a more RO-centric function for fuel handling anyway.

NRC OK.

NRC 2009 MCGUIRE.

Testing on whether the radiation monitor is isolated or bypassed is minutia with the inlet closed, more flow should go through purification filter line, which is a form of bypassing.

Change to If the Letdown HX Outlet Temperature exceeds the setpoint of

____1_____, then flow through the Letdown (Ion Exchangers, ONLY vs Ion E Exchangers AND Radiation Monitor) will be secured.

31 F 2 X X B Added If the Letdown HX Outlet Temperature exceeds the setpoint of ____1_____,

S then flow through the Letdown (Ion Exchangers, ONLY vs Ion Exchangers AND Radiation Monitor) will be BYPASSED using a three way valve. We used Bypassed instead of secured as this is the way it is discussed/trained on in the STM and to say Letdown flow is secured would imply that all Letdown flow is stopped but it is still flowing to the VCT bypassing the Ion exchangers via a three way valve to protect the resin. The Rad Monitor just has a normal MOV isolation valve.

NRC - 2015 Dont say MAXIMUM LEVEL because the setpoint is 6% +/- 0.5%. Say nominal setpoint.

Changed stem as requested.

Part 2 distractor is pretty weak, recommend just making this question part 1, with 4 different answers for level. Consider other distractor options:

Containment Building Sump level = 85% (hi level alarm)

E 43 F 2 X B RWT level = 40%

S Or other setpoints.

Deleted part 2 of the QID and came up with four distractors for RWT level and updated explanations.

In Revision 2, changed the stem to read During a Large Break LOCA, the containment sump isolation valves and RWT outlet valves are interlocked to automatically swap the Containment Spray System (CSS) pump suction source at

__________ level. Added % RWT to A & B. Added inches Containment Flood to C & D based on feedback from the NRC on 2/4/21 phone call.

44 F 2 B S NRC - 2011 Part 2 is weak. Is it realistic to do a 20% load reduction without inserting CEAs? Id rather expand part 1 out to 4 choices. Additional 2 distractors are 60% (power levels for taking a MFP offline on shutdown) and 70% (Main Feed STM says a single MFP is capable of supplying ~ 71% of total system flow while at full power.) Or another value that you think is plausible.

Changed part 2 to which method of boration will be used and made the power level E distractors to 80/60% to be more related to the question and more plausible -

45 H 3 X N S updated explanations. We stayed away from 4 power level choices (60, 70 80, or 90%) because of some conflicting information as to the capacity of a single feedwater pump. As a side note CEAs are always inserted for a normal down power for ASI control but in the case of a loss of a MFW pump, the CEAs are inserted a lot to rapidly reduce RCS temperature or we would trip on low SG level.

Reworded part 2. Initially, the Loss of IA procedure has you verify 3004 open then if IA continues to lower, the procedure directs closing 3004 and then it will remain closed for at least 30 minutes with air from its accumulator even if IA is completely lost to prevent a loss IA on the opposite unit.

Part 2 70% Narrow Range is not plausible. Even part 1 gives away that the highest level EFW might be controlling level at is 62% (which is wrong in itself). So its not logical that OTC would be established when SG drops below a value that is higher than the control range.

E Changed part 2 to 70 and 160 inches Wide range. 70 inches Wide range is the 62 F 2 X N S correct answer. 160 inches Wide range is when you can terminate OTC. Updated explanations for plausibility. 60% Narrow range is our post trip or low power SG level setpoint that is maintained normally by MFW in automatic.

NRC 2-12: Including the alternate phrase (Configuration Control) in the correct answer D looks like cueing, since the reference procedure only uses the term component deviation tagout and the name of the procedure itself is Configuration Control.

In Revision 2 (2-16-21) Removed the words Configuration Control from the stem that renames the procedure number. This phrase in answer D was added based on validation feedback that this tagout is commonly referred to as a Component Deviation Configuration Control Tagout at ANO instead of just Component Deviation Tagout. The Configuration Control Module in the Clearance eSoms program is used IAW EN-FAP-OP-024 Section 3.0 step [3] to generate this record.

Pre-Review REFERENCE PROVIDED This question is very clunky; reads like triage was performed on it to try to justify it as SRO-only. A and B part 1 drop you right into the middle of an AOP, and C and D part 1 drop you into subsections of an FRP.

Effectively correct answer part 1 is expecting the applicant to have memorized which substep of AOP 2203.029 step 7 (substep 7.G) directs checking LPSI header discharge flow within 500 gpm of setpoint, and to know that is the step which if not met redirects you to step 13. That is kind of minutia, not particularly valuable as a discriminating tool, and not really SRO anyway.

This question would be cleaner with explicit diagnosis of the malfunction, operability assessment and TS application.

U New question development in progress 86 H 3 X X N E NRC: Stem: Should say 25 FEET vice INCHES? 19 FEET vice inches?

S NO inches is correct. We base our level on the bottom of the RCS Hot leg being Zero (0) inches. The Hot Leg is 48 inches in diameter and the suction source to the SDC pumps. 24 inches which is the middle of the hot leg is the minimum SDC level to prevent vortexing and air entrainment to the SDC pumps suctions. At 19 inches above the bottom of the hot leg would cause the pump fluctuations as stated in the stem. Added Reference OP-2103.011, Draining the RCS, Attachment B and Exhibit 1 to QID #86 to show this.

-How much time are the validators spending on this question?

Not much more than any other questions. This question is based on new guidance added during the last revision to our EOPs. As long as actions are being taken to recover a lost safety function and the safety function can be recovered within 15 to 30 minutes, then with SM approval, the optimum EOP can remain in effect without going to the FRP.

Pre-Review Why would applicant NOT think that adequate Boron concentration exists? This question would be more discriminatory if the boron concentration in the SFP was something less than 2500ppm but more than 2000. Establish initial conditions such E that SFP concentration only was being considered, Test only on TS 3.9.12 without 93 F 2 X M consideration for 3.9.1.
