Reactor Oversight Process

The Reactor Oversight Process (ROP) is the NRC way issuing finding and violations at a low significance level but also provide a measurement which leads to higher enforcement actions.

Framework

NRC's Overall Safety Mission - Public Health and Safety as a Result of Civilian Nuclear Reactor Operation

Strategic Performance

• Reactor Safety
• Radiation Safety
• Safeguards

Cornerstones

• Barrier Integrity
• Emergency Preparedness
• Initiating Events
• Mitigating Systems
• Occupational Radiation Safety
• Physical Protection
• Public Radiation Safety

Cross-Cutting Areas

Describes the general cause of issues in one of these areas. Branches into cross-cutting aspects.

• Human Performance
• Safety Conscious Work Environment
• Problem Identification and Resolution

Inputs to ROP

Inputs are labeled with a significance; green, white, yellow, red

Findings

Findings are evaluated and given a significance

=Performance Indicators (PI)

Initiating Events

• Unplanned Scram
• Unplanned Power Change
• Unplanned Scrams with Complication

Mitigating Systems

• Safety System Functional Failure
• Emergency AC Power System
• High Pressure Injection System
• Heat Removal System
• Residual Heat Removal System
• Cooling Water System

Barrier Integrity

• Reactor Coolant System (RCS) Activity
• Reactor Coolant System (RCS) Leakage

Emergency Preparedness

• Drill/Exercise Performance
• Emergency Response Organization (ERO) Drill Participation
• Alert and Notification System Reliability

Public Radiation Safety

• Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual (RETS/ODCM)

Occupational Radiation Safety

• Occupational Exposure Control Effectiveness
