EOP Intoduction Flashcards
Define Optimal Recovery Procedures
EOP’s written to treat specific symptoms
Define Functional Recovery Procedures
Undiagnosed or multiple events
Define Lower Mode Functional Recovery Procedure
Events during M4,5, or 6 with LTOP’s in service
When a Safety Function isn’t meeting its Acceptance Criteria, when can we NOT use the FRP or re-diagnose?
Reason for not meeting is known
Actions available to return to acceptance criteria
CRS determines function will be recovered (imminent)
When EOP’s are performed, they are evaluated in Sequential Order, except for when?
- Continuous Action Steps (Monitor, Maintain, Control)
- Trigger Steps (Values, Times passed)
- Hold Point Steps (Must be complete before proceed)
What are “Bracketed Values”? And when are they used?
Values account for uncertainties during DBA’s
Used them during EOP’s to control plant parameters when CTMT is Harsh
How do we obtain a parameters value during a ORP?
AVG of available Qualified Class 1 Indicators (scan)
What is a “Safety Function”?
Condition or Action that prevents core damage or minimizes radiation release to the public
What is a SFSC?

Who reviews and assesses SFSC’s? How often?
CRS (normally assigned to STA)
Checked every ~ 15 minutes
If an EOP step can’t be performed as written, the CRS requires concurrence from whom?
Shift Manager
During EOP’s, when do we worry about Tech Specs?
When specifically required to be reviewed per the EOP
When can we MANUALLY actuate ESFAS signals?
ANYTIME a setpoint is discovered exceeded.
If ESFAS actuation is IMMINENT, what is required to manually actuate?
CRS Concurrence
When can we use an AO or OP during an EOP?
Limit to essential equipment protection, personnel safety and placing systems in Safe condition
