Initial Conditions: Plant is at 100% power. Stator Water Pump B Pump is tagged out due to oil leak.
ESW A & ECC A are running. I&C tech is performing SVI-D23-T1213, Suppression Pool Average Temperature. eSOMS Narrative Log is down. PRA Risk is Green and the Grid Risk is Normal Planned Activities: Start RCIC in CST to CST Mode for vibration testing. Page Jeff Reeves when RCIC is running. NLO has been briefed and is on station to support pump start. When contacted by SCC, lower power to 93% per the Reactivity Plan and IOI-3 Power Maneuvering, for upcoming surveillances. Make any Narrative Log entries on your note pads.
Critical Tasks: 1) Insert control rods.
- 3) Close MSIVs before exceeding 100 °F/Hr. Cooldown rate Event No.

Initial Conditions: Plant is at 85% power. Containment Pressure transmitter 1E12-N062D failed its Surveillance as it could not be adjusted within the allowable value yesterday. PLCO (P19-E12-010) has been generated. eSOMS Narrative Log is down. PRA Risk is Green and the Grid Risk is Normal.
Planned Activities: Shift Fuel Handling Building Exhaust Fans A/C to B/C for planned work. When contacted by SCC raise power to 93% per the Reactivity Plan and IOI-3 Power Maneuvering and hold there for upcoming surveillances. Make any Narrative Log entries on your note pads.
Critical Tasks: 1) Isolate leak into Sec. Containment.
- 2) Isolate Main Steam to SJAE.
- 3) Insert Control Rods Event No.

(BOP)
Initial Conditions: Plant S/U in progress; Main turbine @ 1800 rpm. Ready for Main Generator synch per IOI-3, Step 4.3.35. RFPT A is out of service; installing insulation. TBCC Pump C is out of service for bearing replacement. eSOMS Narrative Log is down. PSA Risk is Green and the Grid Risk is Normal.
Turnover: Planned activities; raise reactor power per IOI-3. Reactor Engineering concurs with gang rod withdrawal where not prohibited. Then synchronize to the grid and continue power ascension.
Make any Narrative Log entries on your note pads.
Critical Tasks: 1) Initiate Suppression Pool leak isolation,
- 2) Insert control rods,
- 3) Manually isolate the Main Steam Lines,
- 4) (Contingency) Initiate Emergency Depressurization Event No.
