EOP Intro and Rules of Usage

Question 1

What are the two direct entry EOP procedures?

Answer 1

• E-0 (Rx Trip or SI)
• ECA-0.0 (Loss of All A/C Power)

Question 2

What are the 3 EOP’s that have immediate actions?

Answer 2

• E-0 (Rx Trip or SI)
• ECA-0.0 (Loss of All A/C Power)
• FR-S.1 (Response to Nuclear Power Generation/ATWS)

Question 3

What conditions define Adverse Containment?

Answer 3

• Containment pressure greater than or equal to 5#
• Radiation levels greater than or equal to 10^5 R/hr
• Temp greater than or equal to 196.8F (when in extended loss of A/C)

Question 4

What are the rules of useage regarding exiting Adverse Containment?

Answer 4

• Once pressure <5#, adverse containment may be exited.
• Once radiation <10^5 R/hr, adverse containment may be exited. However, if levels exceeded 10^6 R/hr, adverse containment must remain in effect.

Question 5

Do continuous action steps apply when transitioning to another EOP?

Answer 5

They apply after transition is made to another procedure if the action is NOT inappropriate for or inconsistent with the strategy of the subsequent EOP.

Question 6

List the 6 Critical Safety Functions in order of priority.

Answer 6

• Subcriticality (S)
• Core Cooling (C)
• Heat Sink (H)
• Integrity (P)
• Containment (Z)
• Inventory (I)

Question 7

List the CSF path classifications in order of priority.

Answer 7

• RED: CSF under extreme challenge
• Orange: CSF under severe challenge
• Yellow: CSF off-normal
• Green: CSF satisfied

Question 8

When must the CSFST’s be monitored?

Answer 8

Begins upon exiting E-0 or when directed in E-0.

Question 9

During what EOP network procedures are the CSFST’s monitored for information only?

Answer 9

• ECA-0.0 thru -0.2
• ES-1.3
• ECA-1.3

Question 10

What are the rules of usage for implementing ES-0.0? (Re-diagnosis)

Answer 10

Shall only be used when the crew is unsure that they have made the correct transition to the proper procedure and:
- SI is in service or is required.
- E-0 has been completed (meaning exited).
- E-series EOP is in progress.

Question 11

Describe the procedure hierarchy.

Answer 11

• FRP takes priority over all plant procedures. (Unless ECA-0 series or ES-1.3)
• EOP takes priority over all plant except FRP’s.
• Emergency remote procedures take priority over the remaining plant procedures.
• AOP’s take priority over ARP’s.
• ARP’s take priority over NOP’s.

Question 12

What do the ORP category numbers mean?

Answer 12

• 0 -> Non Accident
• 1 -> Loss of Primary or Secondary Coolant
• 2 -> Faulted S/G
• 3 -> SGTR

Question 13

In regards to EOP’s, what do the E, ES, and ECA mean?

Answer 13

• E: Guidelines
• ES: Sub-guidelines
• ECA: Emergency Contingency Action Guidelines
