Nuclear Reactor Regulation

On this Page:

Director: William Dean
Deputy Director for Engineering: Brian McDermott
Deputy Director for Reactor Safety Programs and Corporate Support: Michele Evans

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: Robert Taylor (Acting)
Deputy Director: Shana Helton (Acting)

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.

Division of Risk Assessment

Director: Joseph Giitter
Deputy Director: Russell Felts (Acting)

Develops and implements policies and guidance for the use of probabilistic risk assessments in regulatory decision making and rulemaking. Performs and evaluates probabilistic safety assessments for nuclear power plants, evaluates severe accident issues as they relate to new plant designs and current generation plants, evaluates fire protection systems performance, and performs and evaluates accident dose assessments. Develops programs and conducts reviews to ensure the effective consideration of human performance, safety culture, and human factors engineering in nuclear power plant design and operation. Develops and implementing rules, standards, plans, and policy for health physics. Provide expertise for other related purposes such as specific safety issue resolution, special inspections, and event and incident response.
