Critical Task No. 1: Emergency Depressurizes the Reactor when RPV level cannot be restored and maintained above -25 inches.
Time Position Applicants Actions or Behavior
- 1. Safety Significance Emergency depressurization is not performed while RPV water level is above the top of the active fuel because:
! The core will remain adequately cooled as long as RPV water level remains above the Minimum Steam Cooling RPV Water Level.
! The time before RPV water decreases to the top of the active fuel can best be used to line up additional injection sources. If the decreasing RPV water level trend can be reversed, emergency depressurization may not be required.
The emergency depressurization requirement in this step is predicated upon three conditions:
! RPV water level has dropped at least to the top of the active fuel.
! At least one injection source is available.
! The available injection sources cannot restore and maintain RPV water level above the MSCRWL if a blowdown is not performed.
- 2. Cues
- Procedural Compliance
- Decreasing RPV Water Level Trend
- 3. Measurable Performance Indicator At or before a RPV Water Level of -25 inches, at least 5 Safety Relief Valves (preferably all 8 Automatic Depressurization Valves)

Critical Task No. 1: If a primary system is discharging into the secondary containment and has not been isolated, then enter PEI-B13 and scram the reactor.
Time Position Applicants Actions or Behavior
- 1. Safety Significance In the event a primary system is still discharging into the annulus or surrounding containment following previous direction to isolate all systems discharging into the affected area, action is directed to enter PEI-B13 RPV Control (Non-ATWS). Entering RPV Control assures that, if possible, the reactor is scrammed and shutdown by control rod insertion. A scram will reduce the energy level of the RPV to decay heat levels. This accommodates the parallel execution of RPV Control with Containment Leakage Control
