1)

JPM is UNSAT due to K/A mismatch. K/A is 2.1.31, Ability to locate control room switches, controls, indications and to determine whether they correctly reflect the desired plant lineup.

2)

JPM is to conduct a review of a surveillance and determine that it was incorrectly performed and AC Sources Verification is not Sat.

U/E/S 7

Explanation SRO ADMIN LOD REF IC TSK CUE CS TL exists, that two [emphasis added]

safety functions are orange per the key and the key does not state that only one is required. The note as written invalidates the Task Standard and would make the overall JPM UNSAT. Suggestion is to remove the note from the JPM and require that the applicants determine BOTH Orange Safety Functions.

4)

Estimated completion time is 40 minutes.

Suggested change is to have applicants be given the information that Reactivity Control, Fuel Pool Cooling, and Containment have recently been determined to be Green, and Electric Power Control is Yellow; and have them complete Safety Function Status determination for Shutdown Cooling, Inventory Control, and Vital Support Systems and determine Overall Unit Status.

Facility:

1)

Done

2)

No, the BOLD type merely indicates the start of an assessment section. Critical steps are the final determination in each section with an orange rating and are starred in the first column (11, 15, 36)

3)

Deleted note. Included both as critical steps

4)

For now, we are leaving the JPM as is.

We have reduced the estimated time to 20 minutes, to better align with the performance we saw during validation.

My concern is that the NIs will be too difficult to read the current from the images. Are they clear enough for the applicants to properly determine the values such that they will not exceed 1.02? Will have to validate during OSV week.

2)

JPM has many calculations included without acceptance ranges. Each calculation should have an acceptable range to account for potential errors that may be carried forward from initial current calculations.

3)

Acceptance ranges should be included in the highlighted key such that the Task Standard can be met.

Facility:

1)

2)

LOD is not very high as items are borderline direct lookup. In order to remedy this, provide the applicants the procedures for all of the different components that are listed on 134V bus.

3)

Task Standard meets requirements of NUREG. Could be more specific stating each component identified but this is accomplished through the Critical Steps identified in the JPM and therefore the Task Standard is SAT.

4)

See editorial changes in JPM document and update accordingly.

NRC (new comments):

Form 2.3-3 Operating Test Review Worksheet (JPMs) 14 Form 2.3-3 Instructions for Completing the JPM Table

1. Enter the JPM number and/or title.
2. Enter the type of JPM(S)imulator, (P)lant, or (A)dministrative.
3. Enter (Y)es or (N)o for an Alternate Path JPM.
4. Rate the level of difficulty (LOD) of each JPM using a scale of 1-5 (easy-difficult). A JPM containing less than two critical steps, a JPM that tests solely for recall or memorization, or a JPM that involves directly looking up a single correct answer is likely LOD = 1 (too easy).

Conversely, a JPM with over 30 steps or a JPM that takes more than 45 minutes to complete is likely LOD = 5 (too difficult).

5. Check the appropriate block for each JPM error type, using the following criteria:

LOD = 1 or 5 is unsatisfactory (U).

REF: The JPM lacks required references, tools, or procedures (U).

IC: The JPM initial conditions are missing or the JPM lacks an adequate initial cue (U).

CUE: The JPM lacks adequate evaluator cues to allow the applicant to complete the task, or the evaluator cues are subjective or leading (U).

TSK: The JPM lacks a task standard or lacks completion criteria for a task standard (U).

CS: The JPM contains errors in designating critical steps, or the JPM lacks an adequate performance standard for a critical step (U).

TL: The JPM validation times are unreasonable, or a time-critical JPM lacks a completion time (U).

6. Mark the JPM as unsatisfactory (U), satisfactory (S), or needs enhancements (E). A JPM is (U) if it has one or more (U) errors as determined in step 5. Examples of enhancements include formatting, spelling, or other minor changes.
7. Briefly describe any JPM determined to be unsatisfactory (U) or needing enhancement (E).

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

4) For ALL Scenarios, Include the CT # that appears on the Form 3.3-1 cover page with all [CT] markings throughout all of the Scenario Guides and where they appear on the event for best reference back to the CT summaries.
5) CT-14: Is there performance feedback per ES-3.3, Section C.2 such that there is indications that plant conditions are degrading, such as radiation monitors indicating uncontrolled release is in progress while CIVs are open?
6) Add a NOTE prior to first step of ALL Scenario Guides to Ensure that Simulator Data (SBT) is being recorded prior to starting the event. This ensures that in the case of a scenario failure, proper data is recorded for the exam team to evaluate afterwards. Preference is to have a time-interval of 1 second for proper analysis.

3) The turnover mentions that a storm front is moving into the area but may move south of the plant. What is the reason for may move south of the plant? Also, include a storm in at least one other scenario or more for initial conditions.
4) Turnover on Form 3.3-1, refueling is spelled incorrectly
5) Scenario 23-3 Summary Page has U-2 in refiling outage not refueling as well.
6) Turnover Information also has refiling not refueling Facility:
1) Change bounding to Red path on heat sink CSF
2) Left the CT as written but enhanced the reason to include more detail from the USFAR - clarified that the analysis credits operator action within 10 minutes of the event and failure to meet that would put us outside our analysis.
3) Removed the storm aspect from the turnover, summary and changed the SY event to state that a microburst storm hits the switchyard which will be transparent to the applicants - its only in case someone asks why after the exam or something similar.

Credibility Performance Standards Verifiable Actions Critical Task TS CTs:

1) CT described on Form 3.3-1 needs the bounding criteria for CT-13 included on this cover page.
2) For CT-13, there are three (3) different bounds and the procedure transition bound is not explained. Orange path for Subcriticality and Integrity are good bounding criteria. I am not sure why or where BCA-2.1 transition comes into play with this scenario. The crew will be transitioning to H.1 eventually, but I do not think that BCA-2.1 should be a bounding criteria. If the transition to H.1 is desired to be a bounding criteria, then provide description as to why it should be bounding criteria in CT description.
3) Recommend a more definitive, and explainable bound of 100°F from the temp at the trip.
4) CT-43: Spell out minimum in the CT description page, and provide a brief description of what it means to have minimum feedwater or condensate flow (i.e. a Feedwater pump or condensate pump running and feeding the SGs, flowrate is not necessarily required for this condition).

Overall:

5) Bullets are not consistent throughout (open and closed circle bullets, some items not bulleted). Recommend making all bullets the same style to match other scenario guides. Formatting for this guide appears rushed.
6) Scenario 23-4 Summary page:

Event 2: The crew will take make control Should read crew will take manual control?

7) Event 5: the BAR is utilized, will direct the ATC to maintain VTC level change VTC to VCT.
8) Event 5: If the TC takes the 1CV11A switch to the VCT 1CV11A should be 1CV112A?
9) Event 5: Event description on Scenario 23-4 describes a situation in which the ATC takes 1CV112A to the VCT position and a second failure will not occur. What is the second failure? If this is describing the failure of the VCT to auto make-up, then this is not really a second failure as it is built into the failure of 1LT-112 failing High. Please re-word the description for this event to eliminate the description of a second failure and more accurately describe the failure of the VCT to auto makeup due to given event failure.
10) Event 9: We will have to validate this when we get to the OV week. However, having the 1A AF pump trip 10 seconds after the reactor trip is a VERY quick time to have this trip occur. I highly doubt the crew will even have time to diagnose that the 1B AF pump failed to auto-start during this time. Is the intention to have the crew diagnose both pumps failing right away and transitioning to H.1 immediately, or have them attempt to start the 1B AF pump trip while performing E-0 actions? No changes are needed at this time, but please consider these comments and

Credibility Performance Standards Verifiable Actions Critical Task TS have an answer available for discussion prior to and during OV week. I am fine with the trip occurring very quickly but I am curious as to what the intent of the scenario flowpath is and how it is expected to grade the applicants.

6. 1A HD (shaft shear) and 1C HD PP will not start requiring a HD runback U

S NRC:

1) ATC actions to handle the reactivity aspects for the HD runback is not sufficient to properly assess an applicants performance. More information needs to be provided here describing what is expected by the applicant.
2) BOP actions after initial ATC actions are the same actions from Event 1 and should not be included here.
3) Event 6 has no verifiable actions for the BOP pertaining to the HD runback.

This coupled with the additional lack of verifiable actions to grade the ATC makes this event UNSAT.

4) Making this Event SAT will require verifiable actions to be included for the ATC and the BOP that provide enough information for the evaluators to properly assess the applicants.

Form 2.3-3 Operating Test Review Worksheet (Scenarios) 32 CTs:

1) CT-17 bounding criteria of isolating prior to exiting BEP-2 is not an acceptable bounding criteria for this situation. Information provided states that it will affect the Critical Safety Functions. Let the scenario play out and find out which CSF goes ORANGE first and incorporate this as the bounding criteria.
2) CT-12 description on Form 3.3-1 is inadequate and does not include bounding criteria.
3) CT Summary Page has CT-17 listed first and then CT-12 which is contrary to Form 3.3-1. It appears that CT-12 occurs first during the scenario so ensure that these are documented in order of appearance during administration.

Overall:

4) The status of U2 is not in the turnover. Insert status of Unit 2 on ALL scenario turnover sheets for consistency.
5) Scenario does not have reactivity manipulation. Not a requirement per NUREG quantitative assessments per ES-3.4, however, if it is determined that a previous scenario or by some other cause that other scenarios do not have a creditable Rx Manipulation, this scenario will not provide a back up reactivity manipulation to complete the exam requirements.

Scenario 23-5 Summary of Events:

6) Event 5 does not list the specific TS that the SRO applicant will address.
7) Event 7 has two exit paths from BEP-2 to either ES-1.1 or BEP-1. Which is the transition that the applicants are expected to take to be assessed as proper procedure use and adherence by the SRO? Step 7.e of BEP-2 transition to ES-1.1 occurs prior to Step 8, therefore correct transition appears to be ES-1.1 Facility:
1) Orange CSF used to bound CT-17
2) Updated Form 3.3-1
3) Corrected. CT-12 is tricky as it can be completed by 2 different people from 2 different procedures both running in parallel. Ordered them correctly and added clarifying notes prior to each location providing additional guidance for the evaluator.
4) U-2 is only included if its not in Mode 1 with a normal full power lineup OR there is something that would impact U-1 electrical or mechanical cross tie ability.
5) Not required in all guides. Contingency plan, per the Chief Evaluator, will be to add in a minor ramp prior to administration if needed.
6) No formal T.S. action is required for this event. Action listed is TRM and is provided for reference only.
7) The correct transition would be 1BEP ES-1.1 if all of the items in step 7 are met. The guide states that the crew will transition to ES-1.1 and the Note gives the evaluation team the ability to end the set regardless of the direction the crew ends up transitioning. The guide is the grading and the note is for clarifying guidance.

1. For each scenario, enter the scenario event names and descriptions.
2. Review the individual events contained in each scenario, and identify and mark event errors:

The scenario guide event description is not realistic/credibleunsatisfactory (U).

The scenario guide event description lacks adequate crew/operator performance standardsneeds enhancement (E).

The scenario guide event description lacks verifiable actions for a credited normal event, reactivity event instrument/component malfunction, or technical specification (TS) event (or a combination of these) (U).

The scenario guide event description incorrectly designates an event as a critical task (i.e., a noncritical task labeled as critical or a critical task labeled as noncritical). This includes critical tasks that do not meet the critical task criteria (i.e., the critical task does not have a measurable performance standard) (U).

The scenario guide event description incorrectly designates entry into TS actions when not required or does not designate entry into TS actions when required (U).

3. Based on the outcome in step 2, mark the scenario event as unsatisfactory (U), satisfactory (S), or needs enhancements (E). An event is (U) if it has one or more (U) errors as determined in step 2. Examples of enhancements include formatting, spelling, or other minor changes.
4. Briefly describe any scenario event determined to be unsatisfactory (U) or needing enhancement (E). Save initial review comments and detail subsequent comment resolution so that each exam-bound scenario event is marked by a satisfactory (S) resolution on this form.
