Week 7: Emergency Procedures Flashcards
What are the 4 main emergency procedures?
E-0, Reactor Trip or Safety Injection
E-1, Loss of Reactor or Secondary Coolant
E-2, Faulted Steam Generator Isolation
E-3, Steam Generator Tube Rupture
What is the purpose of E-0?
To verify automatic actions as initiated by the protection and safeguard systems
To identify appropriate optimal recovery guideline
To shutdown unnecessary equipment and continue trying to identify optimal recovery guideline
What is the purpose of E-1?
To monitor plant equipment for optimal mode of operation
To check for subsequent failure
To determine optimal method of long term plant recovery
What is the purpose of E-2?
To check main steamlime isolation
To check for at least one non-faulted SG
To Identify and isolate faulted SGs
To check for SGTR
What is the purpose of E-3?
To identify and isolate ruptured SGs
To cooldown and establish RCS subcooling margin
To depressurize RCS to restore inventory
To terminate SI to stop primary to secondary leakage
To prepare for cooldown to cold shutdown

When do you terminate PZR spray flow in E-3?
Both RCS pressure less than ruptured SG and PZR level greater than 4%, or
PZR level greater than 76%, or
RCS subcooling less than 30F
List the major action categories of E-3.
Identify and Isolate ruptured SG
Cooldown
Depressurize
Terminate SI
Prepare for Cold Shutdown
