NRC Performance Goals Ensure protection of the public health and safety and the environment Ensure the secure use and management of radioactive materials PRIMARY GOALS OTHER GOALS
- Ensure openness in NRC regulatory process
- Ensure that NRC actions are effective, efficient, realistic, and timely
- Ensure excellence in NRC management to carry out the NRCs strategic objective
Reactor Oversight Process The NRC monitors plant performance in three The NRC monitors plant performance in three major areas:
major areas:
Reactor Safety Reactor Safety (avoiding accidents or transient &
(avoiding accidents or transient &
reducing their consequences if they occur) reducing their consequences if they occur)
Radiation Safety Radiation Safety (both plant workers & the public (both plant workers & the public during routine operations) during routine operations)
Security Security (protection of the plant against sabotage or (protection of the plant against sabotage or other security threats).....

Reactor Oversight Process
Reactor Oversight Process The ROP includes two separate sources of The ROP includes two separate sources of information:
information:
- Inspections conducted by NRC personnel Inspections conducted by NRC personnel
- Performance Indicators developed from data provided by Performance Indicators developed from data provided by licensees licensees Inspectors can be Site Inspectors can be Site--based or Region based or Region--based based Together they provide a composite picture of how the Together they provide a composite picture of how the plant is being operated plant is being operated
