- *Normal Work Controls**
CDF ≥ 10-6 / LERF ≥ 10-7:
RMAT / RICT apply
Assess non-quantifiable factors
Implements RMAs
- CDF ≥ 10-5 / LERF ≥ 10-6:*
- *Follow Tech specs**
CDF ≥ 10-3 / LERF ≥ 10-4:
Voluntary entry into configuration prohibited
If in configuration due to emergency, implement RMAs

When can risk management actions be applied?
All MODES
Directed by SM and approved by Plant General Manager.
RMAs provide:
- Increased risk awareness and control
- Reduce duration of maintenance activity
- Minimize the magnitude of risk increase
- LOT 802.33 Equipment Maintenance / Operations Interface*
- *
What are schedule levels A/B/C/D?
Level A:
Highest Level of Control
Changes of more than 1 hr require WWM/SM Concurrence
- Level B:*
- *Changes of more than 1 day require WWM/SM Concurrence**
- Level C:*
- *Work included in schedule**
- Most work*
- Level D:*
- *Misc work that may or may not be on schedule**
- LOT 802.33 Equipment Maintenance / Operations Interface*

Can the CRMP be applied if all trains required by the LCO are inoperable?
Yes
≥ 1 train must be PRA Functional
- LOT 802.33 Equipment Maintenance / Operations Interface*
- *
What classifies as emergency maintenance?
Prevent / mitigate an accident
Prevent unplanned release
Protect human life
Prevent significant plant damage
- Authorized by SM
- Does NOT need a work package

What is a work activity risk (WAR)?
Impact on operations during MODES 1 - 4
Primary focus is interruption of power generation
Includes impact of removing / returning equipment.
Work Control / Work week manager develops WAR.
