Deck Covers: E-1, ECA-1.1, ECA-1.2, ECA-1.3, ES-1.1, ES-1.2, ES-1.3, ES-1.4, FR-Z.1, FR-Z.2, FR-Z.3
What are the SI termination criteria given in ES-1.1 (SI Termination)
- Subcooling greater than 40 deg F
- Heat Sink Established (240k PPH OR 13% [28% ADVERSE] NR Lvl)
- RCS Pressure Stable or Rising
- Prz Level greater than 16% (20%) OR ADVERSE 28% (24%)
While in E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if the SG pressure boundary IS NOT intact
- If the faulted SG IS NOT isolated then go to E-2 (Faulted SG)
While in E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if the SG levels are NOT intact
- Maintain feed flow greater than 240k PPH until 13% [28% ADVERSE] NR Lvl
- If level rises in an uncontrolled manner then go to E-3 (SG Tube Rupture)
While in E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if subcooling, heat sink, RCS pressure, and Pzr Level are satisfactory
- Go to ES-1.1 (SI Termination)
In E-1 (Loss of Reactor or Secondary Coolant) what is the purpose of the procedure loop that has you check:
- SG Pressure Stable OR Rising
- RCS Pressure Stable OR Lowering
AND what would the consequence be if you proceeded on with either condition NOT MET (i.e., instead of going to the RNO)
- If SG Pressure is lowering then you need to re-check for a faulted SG
- If RCS Pressure is Rising then you need to re-check if SI termination criteria are met
- Proceeding past this step will transition you to ES-1.2 (Post LOCA Cooldown and Depressurization) which has MORE restrictive SI termination criteria than needed
While in E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if Cold Leg Recirc capability is unavailable
- Go to ECA-1.1 (Loss of Emergency Coolant Recirc)
In E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if there is an Aux Building LOCA
- If ES-1.3 (transfer to Cold Leg Recirc) HAS been completed continue with E-1 (Loss of Reactor or Secondary Coolant) while the PET evaluates the leakage
- If ES-1.3 (Transfer to Cold Leg Recirc) HAS NOT been completed go to ECA-1.2 (LOCA Outside Containment)
In E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if RCS pressure is greater than the shutoff head of the RHR pumps (300#)
- Go to ES-1.2 (Post LOCA Cooldown and Depressurization)
In E-1 (Loss of Reactor or Secondary Coolant) what actions are taken if RWST level is less than 30%
- Go to ES-1.3 (Transfer to Cold Leg Recirculation)
In E-1 (Loss of Reactor or Secondary Coolant) what actions are taken at 7 hours after the event
- Go to ES-1.4 (Transfer to Hot Leg Recirculation)
In ES-1.2 (Post LOCA Cooldown and Depressurization) what actions are taken if Cold Leg Recirc capability is unavailable
- Go to ECA-1.1 (Loss of Emergency Coolant Recirculation)
In ES-1.2 (Post LOCA Cooldown and Depressurization) what actions are taken if there is an Aux Building LOCA
- Consult with the PET to determine source of leakage and go to ECA-1.2 (LOCA Outside Containment)
While in ES-1.2 (Post LOCA Cooldown and Depressurization) what actions are taken if the SG levels are NOT intact
- Maintain feed flow greater than 240k PPH until 13% [28% ADVERSE] NR Lvl
- If level rises in an uncontrolled manner then go to E-3 (SG Tube Rupture)
In ES-1.2 (Post LOCA Cooldown and Depressurization) after the cooldown is started and subcooling is verified greater than 40 deg F what actions is taken if ECCS is in service
- RCS Depressurization using Pzr Spray/PORVs begins
In ES-1.2 (Post LOCA Cooldown and Depressurization) ANY time after SI has been reset AND ECCS pumps have been removed what actions are required if subcooling is lost OR Pzr Level is less than 20% [24% ADVERSE]
- ECCS flow must be MANUALLY established
In FR-Z.1 (Response to High Containment Pressure) if ECA-1.1 (Loss of Emergency Coolant Recirc) is in effect what actions are required
- Operate CTS in accordance with ECA-1.1 (Loss of Emergency Coolant Recirc) while continuing in FR-Z.1
