S NRC: Performance Standard for step 4.1.2h is incomplete. The answer should be -18.3768 pcm with a calculation shown as (-
15.314pcm/F x 1.2F). The first part of the calculation is missing so the 18.3768 units are incorrectly listed as pcm/F and there is no -

NRC: Task Title, Task No., K/A Reference & Rating do not match (likely a copy/paste error). Typo Task standards must be very clear and precise e.g. The operator has identified all valves that must be repositioned (closed) to isolate the leak at 1-WRV-960 on drawing OP-2-5114. Adjusted as requested.
The initial conditions should be more precise has broken should be descriptive/credible e.g. has a crack in the valve body.
Adjusted as requested.
The initiating cue should be more precise about reporting when the task is complete and inform the US should be more declarative e.g. and inform the US when the task is complete. Adjusted as requested.

S NRC: A copy of reference OHP-4021-023-002, Attachment 2 completed through step 4.4 was not included with the JPM. How will step 4.2.5b be filled out which indicates that it was verified the release was approved in Section 2 of Data Sheet 1, since the Data Sheet is intentionally missing the Environmental manager signature?
What is the purpose of including with the JPM the corrected copy of Data 1 which has the Environment approval signature? How is this supposed to be used with this JPM?
Response: Added a completed copy of Attachment 2 to the JPM.
Step 4.2.5.b is incorrectly marked N/A indicating the operator thought the release was approved even though the signature block is blank.
The correctly marked Data Sheet 1 with an Environmental signature included would be used in accordance with the Cue on page 4. The purpose of this action is to require the Candidate to continue the review after the first error is found to ensure completion of sufficient Critical Steps.

Response: Adjusted KA on JPM cover sheet to match Form 3.2-2.
Adjusted Performance standard as follows, including addition of a clarifying note:
NOTE: Stopping the Pump satisfied the Critical Step. Waiting for the pump discharge valve to close is not critical since no flow would pass through the valve even if partially open once the pump is stopped.
STANDARD: (CS) When 1-CRV-252 is CLOSED, Candidate stops the North Heater Drain Pump by momentarily placing the control switch NORTH PUMP 1-PP-22N in TRIP

- 4. Cue indicates that P-7 and P-8 are not lit but P-10 is. The IC starts with the plant at 100%, why would there be a difference in the status of these interlocks with the plant at 100%?
Response: Corrected Form 3.2-2 with KA used by the JPM, as it is the more appropriate KA.
The status of the Permissive lights is correct for a 100% power lineup. The P-7 and P-8 permissives are met when power is less than their respective set point, whereas P-10 is met when power is greater than its set point. Reference Lesson Plan RO-C-01100 Pages 29-31 for more information.

S NRC: The cue/performance standard associated with procedure step g.5 is confusing. The actual procedure indicates that this steps intention is to fail OPEN the valve (1-IRV-311) which was not able to be locally operated. The actual procedure step says to verify 1-IRV-311 is OPEN. But the cue/performance standard says the applicant is expected to verify it CLOSED. Please explain difference. In addition, the Task Standard requires 1-IRV-311 to be failed OPEN.

NRC: Initiating cue (on both the examiner and the applicants copies) has a grammatical error (The Unit Supervisor has directs).
Cues are provided for counter-clockwise motion of the control switches, but there does not appear to be a time when CCW motion is expected. What is the purpose of these cues? Initial motion of the switches is full clockwise through AUTO and into CLOSE, but the next move is again clockwise motion to AUTO. Should this be CCW motion? Was this the purpose of the cues and the performance standards are incorrect?
Response: Corrected initiating cues (both locations).
Corrected performance standard for step 4.3.1.a and 4.3.2.a to indicate the candidate rotates the switch CCW.

- 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.

NRC: TRM 8.1.1 Condition A is required to be entered since RWST auto transfer when VCT level fails off scale is adversely affected. This is a valid TS event and the 3.3-1 and 3.4-1 documents should be properly updated. Per NUREG 1021 TS events include those in which the TS and/or TRM are entered (ODCM entries do not count). This would also make the new event 3 - RCS Flow Instrument failure unnecessary.

Response: If the ATC elects to open 2-QRV-303 to maintain VCT level and pressure, the valve will have to be closed and re-opened repeatedly during the boration in order to keep level and pressure within the control band.

Running CCW Pump Fails (w/ Stby Pump Auto Start Failure)
X E
S Manual start of Standby CCW pump by BOP NRC: What will be the alignment of the standby CCW pump?
Will it be aligned to the simulator unit (unit 2)? The east CCW pump is clearly inoperable. The west CCW pump is also inoperable (unless your TS basis say something else) since it did not auto start. Therefore, if the standby pump is not aligned then it can be argued that there are 2 required trains inoperable and therefore the crew would be in TS 3.0.3 until the spare pump is aligned and in standby.
Response: The standby CCW pump is in Automatic prior to the event. It is dedicated as a Unit 2 pump. After manual start the pump will supply the Unit 2 CCW headers through discharge cross-tie valves without further operator action.
Tech Spec Bases 3.7.7 (ITSA-U2-Bases.pdf) Page 488 states the following:
The pumps are also started on a low header pressure signal, but this is not required for OPERABILITY of the CCW System Since the failure in the scenario is failure of the pressure switch, the West CCW pump remains operable.
5 VCT Level Channel Fails High X

S NRC: For CT2 what is the minimum number of required AFW pumps under postulated plant conditions? Must all three pumps be started or is some lesser configuration acceptable if SG WR level remains above 17%?
E-0, Attachment A the Form 3.3-2 indicates that the applicant should note that Containment Isolation Phase B is actuated.
Why would Phase B be actuated and if it was wouldnt that require RCPs to be shutdown?
Response: According to the ATWS analysis contained in the Westinghouse Emergency Response Guidelines Background (WERG-BD.pdf Page 2497), Auxiliary feed water flow is assumed to begin within 60 seconds at a rate of 1760 gpm
(~880,000 pph). In order to achieve this flow rate, both MDAFPs and the TDAFP must be running. Therefore, in order to comply with the ATWS analysis, all three AFPs must be started if available. In this scenario, all three pumps are available.
