Attachment 6 OBDI 202 - IOLE Process Rev 2 DRAFT OUTLINE COMMENTS Facility:
CPSES First Exam Date:
6/12/17 Written Exam Outline March 16, 2017 Comment Resolution 1
Replacing K/A 005/K1.08 with K1.01.
While true that RHR is not cooled by service water but CCW; CCW is cooled by service water, so the K/A should not have been immediately discarded.
The Chief Examiner agreed to allow the replacement, but did inform the facility to not be so quick to discard K/As if the link between systems is not direct.
2 For the final outline submittal, do not included the question numbers in parenthesis, only the final question number.
Removed parenthesis Administrative JPM Outline March 16, 2017 Comment Resolution 1
Is it possible to make an RO level Admin JPM in Emergency Procedures / Plan?
One has not been performed in at least the previous 8 exams.
Comanche Peak has been unable to make an Emergency Procedures Plan JPM at the RO level.
2 Please add the total number of type codes used in the ES-301-1 forms for both RO and SRO Added the number of type codes Control Room / In-Plant System JPM Outline March 16, 2017 Comment Resolution 1
Please add the total number of type codes used in the ES-301-2 forms for both RO and SRO Added the number of type codes.
2 The ES-301-2 form shows the criteria for the (EN) code to be - / - / 1. The form should be 1 / 1 / 1.
Corrected the form.
3 JPM S-5 may not be an (EN) code, unless the JPM actually has containment spray components being operated. Please verify in the JPM that the intent of (EN) is met.
Discussed with chief examiner, and determined that it does meet the intent of being an EN JPM.
OBDI 202 - IOLE Process Rev 2 Simulator Scenario Outline Comments (Date)
Comment Resolution 1
Scenario 1: During an ATWS, are operators required to drive rods AND emergency borate? If so, then there are two critical tasks. If not, there is only one. The scenario 1 summary for Events 6, 7, and 8 only describe critical task 1.
Removed Critical Task to Emergency Borate 2
Scenario 1: There are several back-to-back events that are from the same scenarios (events 3&4 from same scenario in 2015, events 5&6 from same scenario in 2015, and events 7&8 from same scenario in 2016). Would like to see the following changes: Swap the order of events 2&3. Swap the order of events 4&5. Can you make the cold leg instrument fail low instead of high? For event 8, make the MFIV fail to close instead of the MSIV.
Re-arranged Scenario events 2 & 3.
Discussed with Chief Examiner leaving events 4 & 5 the same. Failed Cold Leg Instrument low vice high. Removed MSIV fails to close, added MFIV fails to close.
3 Scenario #3: This looks to be the newest or most modified and not my initial choice to be the spare, but will make decision during validation.
