Deputy Director for Engineering and Corporate Support:
Brian Holian

NRR is responsible for accomplishing key components of the NRC's nuclear reactor safety mission. As such, NRR conducts a broad range of regulatory activities in the four primary program areas of rulemaking, licensing, oversight, and incident response for commercial nuclear power reactors, and test and research reactors to protect the public health, safety, and the environment. NRR works with the regions and other offices to accomplish its mission and contribute to the agency mission.

Division of Safety Systems

Director: Timothy McGinty
Deputy Director: Robert Taylor

Provides nuclear plant systems-related analysis to assess the appropriateness of changes to existing licenses including amendments, exceptions, extensions, and applications for new facilities or designs. This analysis focuses on plant safety-related and non-safety-related systems (containment, ventilation and balance of plant), core physics, and core thermal hydraulics performance. Provides expertise for other related purposes such as specific safety issue resolution, special inspections, and event and incident response. Develops programs and guidelines to improve generic technical specifications and provides interpretations of technical specification requirements.
