NRC Mission Statement The NRC licenses and regulates the Nations civilian use of radioactive materials, to provide reasonable assurance of adequate protection of public health and safety, to promote the common defense and security, and to protect the environment.

NRC Strategic Goals

1) Ensure the safe and secure use of radioactive materials

2) Continue to foster a healthy organization

3) Inspire stakeholder confidence in the NRC

Resident Inspector Program Resident inspectors live in the communities they serve Perform onsite inspections Provide daily oversight of plant activities, including the control room Routinely discuss safety concerns with plant personnel and senior management Observe emergency drills and provide support to NRC decision makers for actual emergencies or urgent issues

Reactor Oversight Process (ROP)

Implemented in each of the NRCs four regions Involves inspection and assessment activities Executed by regional and resident inspectors 1

ROP Framework

ROP Assessment Inputs Inspection Findings Very low safety or security significance finding Low to moderate safety or security significance finding Substantial safety or security significance finding High safety or security significance finding WHITE GREEN YELLOW RED NRC develops findings from inspections Findings evaluated for safety significance using a significance determination process

ROP Assessment Inputs Performance Indicators (PIs)

Performance within an expected level Performance outside expected range Minimal reduction in the safety margin Signals a significant reduction in safety margin in the area measured WHITE GREEN YELLOW RED Licensees collect PI data (17 PIs total)

PI data reported to the NRC quarterly PI data evaluated & integrated with inspection findings to develop NRCs assessment of licensee performance
