Appendix D Scenario Outline Form ES-D-1 Scenario summary:
Plant is at 100% power, End of life (EOL). Emergency Diesel Generator (EDG) B is tagged out/out of service for Maintenance - Preventative Maintenance (PM). Expected return is six hours. Technical Specifications (TS) 3.8.1 condition A & B entered. STS NB-005, Breaker Alignment Verification, complete (due in seven hours).
Motor Drive Auxiliary Feedwater Pump (MDAFWP) B is tagged out/out of service due to Emergent work (SM Concern). Expected return is six hours. Technical Specification 3.7.5 condition B entered.
Pressurizer (PZR) controlling level channel BB LI-459A fails high. Crew responds using OFN SB-008, Instrument Malfunctions, Attachment J.
- Attachment J: Select an alternate level channel as the controlling channel.
- Crew stabilizes the plant.
Condensate pump A trips. The crew responds by entering OFN AF-025, Unit Limitations.
Attachment A will require a downpower evolution.
Downpower guidance per OFN AF-025: If one condensate pump is lost, reduce power as necessary to maintain Main Feed Pump (MFP) suction pressure greater than 340 psig on AEP0006 for A MFP and AEP0005 for B MFP.
- Crew responds by performing a downpower.
- Crew stabilizes the plant.
A seismic event occurs resulting in an inadvertent reactor trip. EMG E-0, Reactor Trip or Safety Injection is entered. (Major event)
Post trip, both NB01 and NB02 busses trip. Due to the Maintenance PMs (see Turnover item),
Emergency Diesel Generator B will not start and load onto NB02 bus. The Control Room must manually start Emergency Diesel Generator A and then it will load onto NB01 bus.
As the scenario progresses, the Turbine Driven Auxiliary Feedwater Pump (TDAFWP) trips due to broken linkage and the Motor Driven Auxiliary Feedwater Pump A will trip due to shaft seizure and BOTH cannot be restarted. Motor Driven Auxiliary Feedwater Pump B cannot be started (see Turnover item). No Auxiliary Feedwater (AFW) to the Steam Generators is available. Note that the running CCP (CCP A) trips off due to overcurrent.
The crew enters EMG FR-H1, Response to Loss of Secondary Heat Sink (Major event).
Mitigation strategy: the crew uses the Foldout page of EMG FR-H1, Bleed and Feed.
EMG FR-H1, Response to Loss of Secondary Heat Sink, Major Actions:
- Attempt restoration of RCS bleed and feed flow to the S/Gs
- Initiation of RCS bleed and feed heat removal
- Restore and verify secondary heat sink 3
- 1. Starting the EDG A to re-energize NB01 bus before placing safeguards equipment in pull-to-lock or prior to any needless Orange or Red path entry conditions.
- 2. Establish RCS bleed and feed before Steam Generators (SG) dry out establishing a heat sink for the core.

ROs must serve in both the at-the-controls (ATC) and balance-of-plant (BOP) positions; Instant SROs must serve in both the SRO and the ATC positions, including at least two instrument or component (I/C) malfunctions and one major transient, in the ATC position.
If an Instant SRO additionally serves in the BOP position, one I/C malfunction can be credited toward the two I/C malfunctions required for the ATC position.
- 2. Reactivity manipulations may be conducted under normal or controlled abnormal conditions (refer to Section D.5.d) but must be significant per Section C.2.a of Appendix D. (*) Reactivity and normal evolutions may be replaced with additional instrument or component malfunctions on a 1-for-1 basis.
