Unit 2 is at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump are tagged out for preventative maintenance. Turnover: Unit 1 just below POAH, BOL. Unit 2 at 100%. 1B NI (Safety Injection) Pump and the 1D RC (Condenser Circulating Water) Pump tagged out. The crew is to shift operating KC (Component Cooling) pumps by starting the 1B2 KC pump and securing the 1B1 KC pump and then increase power 1%. Event 1 Shift operating Component Cooling pumps per OP/1/A/6400/005 (Component Cooling System), Enclosure 4.17 (Shifting KC Pumps). Event 2 Raise reactor power to 1%. Crew will use rods since unit is below POAH. Event 3 1D S/G W/R level signal fails LOW; associated Feed Reg. Bypass Valve opens. RO takes manual control to stabilize and restore 1D S/G level. AP/06 (Loss of SG Feedwater) Case III entry. This failure is internal to the DCS and does not indicate on the W/R level board indication. Event 4 AP/20 (Loss of Nuclear Service Water) entry. TS evaluation will indicate no LCO entry required. Event 5 1B Main Feedwater Pump trips, along with the failure of the 1B AFW pump to auto start. AP/06 Case I entry. A TS evaluation required due to failure of the 1B AFW pump to start. Event 6 1A NV Pump (Charging) trips. BOP manually starts the 1B NV pump to restore charging and letdown. AP/12 (Loss of Charging or Letdown) will be entered. TS evaluation required. Event 7 1NC-36B (PZR PORV) fails open. RO attempts manual closure of the PORV. This will not be successful. AP/11 (Pressurizer Pressure Anomalies) entry. This is the major event because the PZR PORV cannot be closed, nor will the manual block isolation close. Recognizing a LOCA, the crew will determine that the reactor must be tripped. Event 8 1A NI (Safety Injection) Pump fails to auto start on the SI signal. BOP manually starts to establish intermediate head injection flow. Event 9 1CA-152 (S/G 1D CF BYP TO CA NOZZLE) fails to close on the feedwater isolation. RO manually closes the valve. Critical Task 1 Establish flow from at least one intermediate head ECCS pump prior to transition from E-0. Critical Task 2 Trip NC pumps on loss of subcooling with S/I flow verified per E-0 within 5 minutes of criteria met.
