5 Control Room / In-Plant System JPM Outline (9/19/2014)

Comment Resolution For JPM S-2, I dont see how an ARC Changing this one. Done and is now Sat.

1 pump is part of reactor water level control Safety Function 2.

For JPM S-3, I dont see how adjusting Words not right but it is actually changing MT recirc pump seal pressure is part of pressure so it is okay.

2 reactor pressure control Safety Function 3.

For JPM S-4, can you give me the KA for Changing this one. Done and is now Sat.

this JPM and its importance rating? I 3 dont think this relates enough to Safety Function 4 for heat removal from the core to be on the NRC exam.

Why on the last three exams have there Two boards not modeled in simulator so that been exactly two control room JPMs? is why they did it this time. Dont have a 4 standard for doing this every time so not sure why it has occurred. Discussed the idea of predictability and they understand.

For JPM C-2 how is this a Safety This is an instrument failure that causes the 5

Function 7 Instrumentation JPM? rod to have to be bypassed so it is okay as OBDI 202 - IOLE Process Rev 1

written.

Too many Low power sim JPMs? Six out Changing to four JPMs at low power. Done of eight total are low power. and is now Sat.

Requirement is at least one but most of 6

them at low power is not good either.

Should have a better balance of low and normal power JPMs.

For S-1 JPM: Do you use an Abnormal Yes. It is okay as written.

7 Ops Procedure for this JPM? If not then this is not an E JPM.

Simulator Scenario Outline Comments (9/19/2014)

Comment Resolution General comment for scenarios-it helps you and us if you include a short narrative (as page 2 of the D-1 form) that 1

explains the basics for each event, the TS calls, and includes the critical tasks, their bases, and bounding conditions.

Scenario 1- Yes-going to add another TS call. Dont want a) Only one TS call in this scenario? to change the SRV for now since its leakage b) For event 3 RHR A pump trip, issue becomes the total failure in the major.

make that a shaft shear to be They agreed to change the pump trip to shaft different that previous exam shear. Done and is now Sat.

2 events on RHR pump events.

c) Discuss changing the SRV that fails open (ie make it a different one than 51C to challenge the scenario a little more)

Scenario 2- Yes-need to add one more TS call. Done and 3

a) Only one TS call in this scenario? is now Sat.

Scenario 3- Okay on the shaft shear change. For the a) For event 7, make it a shaft shear pump swap it is okay as written and when the instead of simple trip for Stator update is submitted for the outlines it will be water pump A. clear what happens with the pumps. Done 4 b) If event 1 is a swap from A to B and is now Sat.

stator water pump, how can event 7 have a trip of the A pump- it wouldnt be running would it? OBDI 202 - IOLE Process Rev 1

Scenario 4 - Licensee looking at the bean balance to see if a) Need better balance for the BOP they need to change one. The ATC does the position on the front-end of the turbine MVAR event so it is correct for this scenario. Need to remove an panel as written.

ATC event and replace with a 5 BOP event.

b) Question - Does the ATC control turbine and reactor at RBS (event 2 has the ATC adjusting MVARs-not normally what we are used to seeing)? OBDI 202 - IOLE Process Rev 1
