NRC: JPM Step 4 (Step 4.7.1) performance standard incorrectly states verify 1DH831 is closed. It should verify that 1DH830 is closed.

JPM Step 13 performance standard expects the applicant to sign Section 4.y completed by line. What is section 4.y? JPM Step 10 already expects the applicant to sign Section 4.7 completed by line.

Validation time seems much too long, 15 minutes seems much more reasonable.

This JPM is listed as modified. Provide the original JPM or indicate what is modified from the original version of this JPM.

Licensee:

Changed JPM Step 4 performance standard to verify DH830 is closed.

4.y is a typo. Should be 4.7.

Removed, Sign Section 4.7 from JPM Step 13 performance standard.

NRC: Task Standard does not agree with the performance standard of critical JPM Step 6. Critical Step 6 performance standard requires total loop flow to be calculated between 406-407 KGPM. This is an appropriate band. The Task Standard states that total flow will be calculated between 405 and 407 KGPM.

This is too wide a band. Even if the applicant does not interpolate and uses the lowest possible specific gravity (0.02166 at 2200 psia/560F) they will still calculate a total flow just above 406 KGPM.

Why are we giving the applicants Attachment 1, Page 4?

The JPM does not indicate the applicant is expected to verify the performance criteria is met. If this is expected, an additional step should be added to the JPM.

Licensee:

Changed Task Standard to match JPM Step 6 (406-407 KGPM)

ES-301 Operating Test Review Worksheet Form ES-301-7 Removed Attachment 1, Page 4 from the list of Required Materials and Initial Cue.

S NRC: JPM Step 3 cue indicates that the applicant should be told that another operator will place an OOS placard on RE1878B1 after the applicant determines that it is turned off. In the JPM setup instructions, an OOS is to be placed on RE 1878B1 before the JPM is started. Correct the setup instructions to match the cue and do not place an OOS tag in the instrument until it is determined to be off by the applicant.

Licensee:

E S

EARLY SUBMITTAL NRC:

1.

Explain why DB-OP-02000, Step 3.3 RNO 4 and the JPM Task Standard are not the same (and vs.

or).

2.

The Note for JPM step 2 should also be included for JPM Step 3.

3.

Does the 3rd Initial Condition need to be provided?

(Concern with overlap with CT-24: Shutdown Reactor-ATWS in Scenario 2)

4.

The scope of the JPM is very narrow. Can this be enhanced?

Response

1.

It is only critical to open breaker A or C and B to cause an actual reactor trip. If the applicant opened Breakers A and B the reactor would trip which is the critical nature of this JPM.

They would be subject to a comment for procedural compliance by not also tripping breaker C. Hence the difference between the procedure step and the task standard.

2.

Added note to JPM Step 3.

3.

Removed 3rd initial condition.

4.

The JPM tests the ability of applicants to locate and manually open reactor trip breakers, as well understand reactor trip logic and is therefore a discriminating test tool.

Walkthrough comments Added a note prior to step 2, NOTE: It is only critical to trip CRD Breaker A or C.

NRC: The JPM is SAT.

NRC: The JPM is SAT.

S2 (JPM 291)

SF 2 -

K/A 006 A4.05 3

X X

E S

EARLY SUBMITTAL NRC:

1.

Clarify for JPM step 1 - would it be expected procedurally to press all 4 BLOCK pushbuttons?

2.

Clarify for JPM step 7 - what would the impact be if any additional Train 2 SFAS Level 5 Output Modules were tripped?

Step 1 is necessary as the valves need to be repositioned to support an ESFAS level 5 (low BWST level) and therefore the signal for ESFAS level 2 (Safety Injection) needs to be overridden. 2 still needs to be addressed.

ALSO - The procedure indicates that it is a time critical action to open a sump suction valve from when 9 feet in the BWST is achieved. Since the 9B valve opens without having to implement alternate path actions, it seems like this can still be tested. Please explain this.

Licensee:

1.

Yes, it would be expected to press all 4 BLOCK pushbuttons by procedure. Changed standard to depress all 4 pushbuttons. Added a comment that its only critical to verify all 4 valves are blocked.

2. There are no other Level 5 Output Modules. If the wrong output modules are tripped, then DH9A and DH7A will not reposition.
3. Not tested as a time critical action since its an Alternate Path JPM. Time critical steps will be added just for DH9B.

Walkthrough comments

1.

Changed task standard to: Transfer LPI Suctions to the Emergency Sump Time critical JPM to transfer Train 1 Suction to the Emergency Sump within 2 minutes.

2.

Validation time to 10 minutes

ES-301 Operating Test Review Worksheet Form ES-301-7

3.

Deleted, This is a Time Critical JPM. I will inform you when the Time Critical Clock begins from the initial cue. Changed cue to (Unfreeze simulator and mark Time Critical Clock start time when examinee is ready to start JPM)

4.

Deleted Cue Time critical clock starts now from the Start Time box. Changed start time box to, Time Critical Clock START TIME:_________

NRC: Two issues remained - we need to indicate that this is a time-critical JPM in the cue (per Appendix E, page E-4) and change the validation time to 10 minutes as stated above. Both items Corrected - The JPM is SAT.

S NRC: This JPM is listed as modified. Provide the original JPM or indicate what is significantly modified from the original version of this JPM.

The comment regarding HPI flow in JPM Step 8 is awkward and difficult to understand - Reword it to clarify what is being described.

The K/A selected was not the best. AA1.22 obtaining water from the BWST for LPI is not perfect but is better than the one selected as LPI pumps are tripped at the onset of the JPM and the applicant is directed to establish feed and bleed from the BWST. LPI pumps are tangential to the applicants response of this JPM.

S NRC: Why are the CV5011 valves not closed as a part of this JPM? They appear to be in direct contact with the containment atmosphere similar to the CV5010 valves which are shut in the JPM?

The cue should correct the word indirect for JPM Step

3. It should be two words in direct to have proper meaning for this situation.

Licensee:

Form ES-301-7 Instructions for Completing This Table:

Check or mark any item(s) requiring a comment and explain the issue in the space provided using the guide below.

1.

Check each JPM for appropriate administrative topic requirements (COO, EC, Rad, and EP) or safety function requirements and corresponding K/A. Mark in column 1.

(ES-301, D.3 and D.4)

2.

Determine the level of difficulty (LOD) using an established 1-5 rating scale. Levels 1 and 5 represent an inappropriate (low or high) discriminatory level for the license that is being tested. Mark in column 2 (Appendix D, C.1.f)

3.

In column 3, Attributes, check the appropriate box when an attribute is not met:

The initial conditions and/or initiating cue is clear to ensure the operator understands the task and how to begin. (Appendix C, B.4)

The JPM contains appropriate cues that clearly indicate when they should be provided to the examinee. Cues are objective and not leading. (Appendix C, D.1)

All critical steps (elements) are properly identified.

The scope of the task is not too narrow (N) or too broad (B).

Excessive overlap does not occur with other parts of the operating test or written examination. (ES-301, D.1.a, and ES-301, D.2.a)

The task performance standard clearly describes the expected outcome (i.e., end state). Each performance step identifies a standard for successful completion of the step.

A valid marked up key was provided (e.g., graph interpretation, initialed steps for handouts).

4.

For column 4, Job Content, check the appropriate box if the job content flaw does not meet the following elements:

Topics are linked to the job content (e.g., not a disguised task, task required in real job).

The JPM has meaningful performance requirements that will provide a legitimate basis for evaluating the applicant's understanding and ability to safely operate the plant. (ES-301, D.2.c)

5.

Based on the reviewers judgment, is the JPM as written (U)nacceptable (requiring repair or replacement), in need of (E)nhancement, or (S)atisfactory? Mark the answer in column 5.

6.

In column 6, provide a brief description of any (U)nacceptable or (E)nhancement rating from column 5.

S NRC: Address concerns raised above. Note that this scenario, while a discriminating tool, does not require either the ATC or BOP to manually control a parameter which is normally controlled automatically or start a component which is normally automatically started. This may have an adverse impact on the examiners ability to assess all candidates in the rating factors of Competency 3.

Licensee: ATC: An additional malfunction was added to prevent the automatic start of the standby CCW pump after the in-service pump trips. This will require ATC to take manual action after the automatic action fails.

This should be evaluated as a critical task. Will determine during NRC Walkthrough per Lead Evaluator.

BOP: Station Air Compressor 1 will NOT automatically start on lowering instrument air header pressure. BOP is expected to manually start SAC 1 AND verify instrument air header pressure is rising.

NRC: Why is TS 3.3.9 referred to with an open bullet? Why are TS 3.3.9 LCO Conditions A and B listed when Condition C is the correct condition to enter. The reactor will still be at > 1E-10 Amps and both SRNIs will be turned off so inoperable. If the note applies and Condition C is not entered than I am assuming you are considering that the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> action due to TS 3.3.10 drove the applicants to lower power < 1E-10 and then you listed A and B. B would require an immediate shutdown. Please explain in greater detail your intentions with this TS call.

Licensee: Scenario guide was changed to have the Shift Manager direct ATC to lower Reactor Power until Source Range Nuclear Instruments are on scale and NOT de-energize the source range instruments to avoid this concern.

An additional malfunction (Event 3) was added to provide an opportunity for the BOP operator. LT421 for #1 Deaerator will fail high resulting in CD 421 failing closed. #1 Deaerator level will lower. The low-level alarm will actuate at 7.25 feet after approximately 10 minutes. BOP is expected to place CD 421 in manual and control #1 Deaerator level. The failure may be identified by the BOP prior to receiving the alarm.

ATC manually starts CCW2 NRC: Provide detail as to the 5 minute boundary condition for starting CCW2. If the diesel is expected to be damaged by running without cooling water for 5 minutes, then please state that in the critical task analysis. Otherwise, this does not become an issue until SCM is lost later in the scenario.

Licensee: Added the following information from the BASES AND DEVIATION DOCUMENT FOR DB-OP-02000 to the analysis.

The CCW and SW pumps are checked to ensure cooling water is available to the EDG. Operation without CCW or SW will lead to EDG overheating and failure. The EDG is shutdown if SW or CCW is not available. PCAQ 98-1883 reviewed the time available to perform the EDG Shutdown. Based on discussions with EDG vender (documented in the PCAQ), in a loaded condition, the EDG Jacket Water would reach the high temperature shutdown setpoint in approximately 3 minutes. If the EDG continued to run, the cylinder head would likely crack in approximately 6 minutes, and the EDG would likely seize in 11 to 14 minutes. The critical task time of 5 minutes is used to provide margin to possible failure at 6 minutes.

ES-301 13 Form ES-301-7 Instructions for Completing This Table:

Use this table for each scenario for evaluation.

2 Check this box if the events are not related (e.g., seismic event followed by a pipe rupture) OR if the events do not obey the laws of physics and thermodynamics.

3, 4 In columns 3 and 4, check the box if there is no verifiable or required action, as applicable. Examples of required actions are as follows: (ES-301, D.5f) opening, closing, and throttling valves starting and stopping equipment raising and lowering level, flow, and pressure making decisions and giving directions acknowledging or verifying key alarms and automatic actions (Uncomplicated events that require no operator action beyond this should not be included on the operating test unless they are necessary to set the stage for subsequent events. (Appendix D, B.3).)

5 Check this box if the level of difficulty is not appropriate.

6 Check this box if the event has a TS.

7 Check this box if the event has a critical task (CT). If the same CT covers more than one event, check the event where the CT started only.

8 Check this box if the event overlaps with another event on any of the last two NRC examinations. (Appendix D, C.1.f) 9 Based on the reviewers judgment, is the event as written (U)nacceptable (requiring repair or replacement), in need of (E)nhancement, or (S)atisfactory? Mark the answer in column 9.

10 Record any explanations of the events here.

In the shaded boxes, sum the number of check marks in each column.

In column 1, sum the number of events.

In columns 2-4, record the total number of check marks for each column.

In column 5, based on the reviewer's judgement, place a checkmark only if the scenario's LOD is not appropriate.

In column 6, TS are required to be 2 for each scenario. (ES-301, D.5.d)

In column 7, preidentified CTs should be 2 for each scenario. (Appendix D; ES-301, D.5.d; ES-301-4)

In column 8, record the number of events not used on the two previous NRC initial licensing exams. A scenario is considered unsatisfactory if there is < 2 new events. (ES-301, D.5.b; Appendix D, C.1.f)

In column 9, record whether the scenario as written (U)nacceptable, in need of (E)nhancement, or (S)atisfactory from column 11 of the simulator scenario table.

Instructions for Completing This Table:

Check or mark any item(s) requiring comment and explain the issue in the space provided.

1, 3, 5 For each simulator scenario, enter the total number of events (column 1), TS entries/actions (column 3), and CTs (column 5).

This number should match the respective scenario from the event-based scenario tables (the sum from columns 1, 6, and 7, respectively).

2, 4, 6 For each simulator scenario, evaluate each event, TS, and CT as (S)atisfactory, (E)nhance, or (U)nsatisfactory based on the following criteria:

a.

Events. Each event is described on a Form ES-D-2, including all switch manipulations, pertinent alarms, and verifiable actions. Event actions are balanced between at-the-controls and balance-of-plant applicants during the scenario. All event-related attributes on Form ES-301-4 are met. Enter the total number of unsatisfactory events in column 2.

b.

TS. A scenario includes at least two TS entries/actions across at least two different events. TS entries and actions are detailed on Form ES-D-2. Enter the total number of unsatisfactory TS entries/actions in column 4. (ES-301, D.5d)

c.

CT. Check that a scenario includes at least two preidentified CTs. This criterion is a target quantitative attribute, not an absolute minimum requirement. Check that each CT is explicitly bounded on Form ES-D-2 with measurable performance standards (see Appendix D). Enter the total number of unsatisfactory CTs in column 6.

7 In column 7, calculate the percentage of unsatisfactory scenario elements:

8 If the value in column 7 is > 20%, mark the scenario as (U)nsatisfactory in column 8. If column 7 is 20%, annotate with (E)nhancement or (S)atisfactory.

9 In column 9, explain each unsatisfactory event, TS, and CT. Editorial comments can also be added here.

Save initial review comments and detail subsequent comment resolution so that each exam-bound scenario is marked by a (S)atisfactory resolution on this form.
