Study Notes
Definitions Overview
- Back Stop: The maximum time allowed to complete actions regardless of RICT. It's set at 24 hours for safety function loss and 30 days for other conditions.
- Barrier: Physical components that protect a system from initiating events, not specified in Technical Specifications.
- Configuration Risk Management Program (CRMP) Software: Tool for assessing the impact of equipment configurations on plant safety during maintenance activities.
Core Damage and Risk Metrics
- Core Damage Frequency (CDF): Predicts the likelihood of accidents causing core damage in one reactor year, calculated using CRMP or PRA methods.
- Degraded Barrier: A barrier that needs repair or adjustment for maintenance.
- Incremental Core Damage Probability (ICDP): The risk change attributable to out-of-service SSCs or certain conditions, reflecting a specific plant configuration impact.
Operational Risk and Management
- Opportunities for Risk Management Actions (RMA): Measures aimed at reducing risks associated with maintenance and functioning of plant equipment.
- Risk Informed Completion Time (RICT): Time frame for addressing conditions needing entry into Technical Specifications, capped by 1E-5 ICDP or 30 days.
- Planned RICT: RICT used for pre-planned maintenance tasks, distinguishing itself from emergent conditions.
Risk Definitions
- Instantaneous Risk: The expected core damage or large early release frequency at a specific timeframe without duration consideration.
- Probabilistic Risk Assessment (PRA): A quantitative risk evaluation associated with plant operations.
- Zero-Maintenance Risk: The baseline risk level assessed when all relevant components are in service without special conditions.
Work Management and Constraints
- Plan of the Day (POD): A document that outlines current and impending work, especially regarding maintenance systems.
- Front Stop: Prescriptive period for completing a Required Action outlined by Technical Specifications (e.g., 72 hours).
Risk Management Approaches
- Non-Fire RMA Levels: Actions to minimize initiating events, categorized into three levels based on impact on risk awareness and control.
- Common Cause RMAs: Focuses on the resilience of redundant systems in the event of a failure.
- Risk Managed Technical Specifications (RMTS): Enhancements in Technical Specifications derived from probabilistic assessments.
Risk Assessment Timing
- Event Start Date: Marks when the first LCO exceeds its front stop.
- Risk Management Action Time (RMAT): The point at which risk action thresholds are activated, requiring intervention.
Software and Interfaces
- CRMP Interfaces: Software connections for integrating work scheduling and clearance processes, ensuring seamless communication of plant configurations.
Other Important Concepts
- Environmental Change: External conditions significantly increasing risk, such as severe weather.
- Emergent RICT: A reactive RICT triggered by unanticipated equipment failures requiring immediate entry into LCO.
