Misspelled dose as does several times in steps 1 and 2. Corrected 2.
Step 2 gives a calculation with the wrong time value. It shows 6 minutes when it should be 8 minutes. This changes the calculated dose from 0.37 R to 0.49 R. This error carries forward and changes the final answer to 1.65 R instead of 1.77 R. Again, the error carries forward and the calculation becomes 1.65/9.51 =

- 2. For the examiner state that the actions listed are from the hard card. Note added for the examiner.
- 3. First step should be for the CD/CB pump to trip and there should be a note/que that the standby pump fails to start automatically as required.
Note/cue added.
- 4. In the JPM Summary the JPM states it is not an Alt path but there is an Alt path for a CD pump trip in the 3.2-2.
Which is it? It is not an alt path per NUREG 1021. It is not an Alt path JPM and the form has been corrected to remove Alt Path

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.

If the ATC is expected to take manual control of letdown then letdown should not be isolated.
Is the ATC expected to be able to take manual control? With the change above and below this comment is now moot 4.
This failure was in the 2019 and the 2021 exam and is now in this exam. Recommend that it not be re-used in this exam.

Form 2.3-3 Instructions for Completing the Scenario Table
- 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.
