Palo Verde 2021-04 Draft Operating Test Comments NOTE: This summary is being provided in lieu of Form 301-7, Operating Test Review Worksheet, because the licensees operating test submittal was reviewed and overall deemed SATISFACTORY.
Scenario 1:
Enter event 2 as soon as level >70 for event 1 Event 3: BOLD RCB-PI-101B in second block (page 10)
Event 3: PPS bypass procedure needs to be evaluated to remove TS 3.3.5 Event 4: Add note that B CEDM ACU cannot be overridden Event 4: include Appendix C steps that could affect TS Event 5: Change bounding criteria; restore power to FSAR time limit (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />)
Event 5: Add information about how the crew will handle the Main Generator Output Breakers in SPTAs since the generator is not synched to the grid Event 5: Add examiner note indicating how Controlled Bleedoff is isolated following the loss of power (SPTAs)
Scenario 2:
Event 2: add steps to lower turbine load if needed Event 4: add time limits for loss of NC water (10 min. to trip RCPs; 3 min. if no NC + no CHV)
Event 4: Fix order of steps on page 13 (if cross-connecting and Ensure that no more than one)
Event 4: Add note about the crew not stopping the last Charging Pump until cooling water has been restored to the RCPs Event 4: add not to initiate event 5 if reactor is manually tripped in event 4 Event 5: add alternate success path for CT-2 Event 5: Add note for driver not to energize HPSC isolation valves (if directed during SPTAs) until SIAS/CIAS actuated to ensure CT-1 is valid Event 5: Add HPSC isolation valve numbers for CT-2 Event 5: add CT-3; 30 min. time limit to trip RCPs on loss of NC Scenario 3:
Event 1: make note for examiner to follow up if TS 3.6.3 is conservatively entered Event 2: add steps to place CEDMCS and SBCS in auto (may need SM prompt)
Event 6: Delete trip of RCPs as a CT (not critical for this event)
Event 7: Delete 5 min. delay on CS pump trip Add start/stop times for CS CT
Scenario 4:
Event 3: Add note NOT to transition to event 4 until procedural step to address DNBR is entered Delete the three blocks on page 13 (unnecessary)
Event 4: add note - dont go to event 5 until boron equalization terminated (page 14)
Event 5: add list of components that could be realigned due to sequencer failure Terminate scenario when Thot is at 540° Make spare scenario JPM S-1:
Step 13: add examiner note to supply applicant with alternate path procedure Step 16-18: possible cues from outside operator that HPSI pump UC fuses are ON Step 22: add which valves are applicable JPM S-2:
Initial Conditions should say tripped ON overcurrent instead of tripped IN overcurrent Step 10 should list the valve numbers Step 12 - Does it need some sort of minimum flow (Figure 2)? Is there a high limit on flow?
Validation time 8 minutes JPM S-3:
Add in task standard: secure aux spray before reaching low Rx trip setpoint (app. 1960)
Make step 1 non-critical Add step 10 to secure aux spray prior to reaching low pressure Rx trip setpoint Make JPM non time critical (time bounded by potential automatic reactor trips)
JPM S-4:
JPM Step 6 and JPM Step 11 procedure note is wrong (copy and paste error)
Add except where specified at the end of the task standard JPM S-5:
Steps to start AFN-P01 need to include downcomer valves Need to ensure the SG is actually being fed prior to initiating Key 1
Consider adding information about potentially going to AFB with degraded performance/sheared shaft Add what do you recommend cues as appropriate during the alternate path Examinee may ensure the downcomers are closed prior to attempting to restart AFN Insert inadvertent SIAS after MFPs are secured JPM S-6:
Change validation time to 8 minutes JPM S-7:
Add note to Step 10 that the synch key may have been placed in ON during Step 7 to restore frequency indication for the B EDG In Step 5 task standard add (skill of the craft)
JPM S-8:
In initiating cue, add time permits all procedurally directed actions prior to exiting the control room JPM P-1:
RCA JPM Not time critical. Time critical tasks bounded by twice validation time Terminate JPM after step 7 (inform CRS)
JPM P-2:
Revise to ensure the trip throttle valve is manually closed, reset, and opened by using Appendix 40 JPM P-3:
Step 1 cue should be light is lit Steps 2-7 need to indicate valve handles are in line with the pipe for task standard Step 11 cue as you see it Step 14 cue all annunciators extinguished and EDG is rumbling GENERAL ADMIN JPM COMMENT
For all applicable JPMs, add answer key that can easily be compared to applicants submittal JPM A-1:
JPM A-2:
JPM A-3:
JPM A-4:
Change validation time to 10 minutes JPM A-5:
JPM A-6:
JPM A-7:
JPM A-8:
JPM A-9:
Update cover sheet to indicate time critical JPM
