Director: Ho Nieh
Deputy Director for Engineering: Mirela Gavrilas
Deputy Director for Reactor Safety Programs and Mission Support: Michele Evans (Acting)

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 Resource Management and Administration

Director: Ashley Roberts
Deputy Director: Frederick Miller

Provides mission and program support to the Offices of Nuclear Reactor Regulation (NRR) and New Reactors (NRO), and the Operating Reactor and New Reactor Business Lines. Enables NRR and NRO to operate efficiently and effectively by overseeing administrative services, human capital management, information management, financial management, performance management, internal controls, and coordinates the annual Regulatory Information Conference.

Division of Safety Systems

Director: Jane Marshall (Acting)
Deputy Director: Michael Waters (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 Engineering

Director: Eric Benner
Deputy Director: Brian Smith

Provides safety evaluations of licensee's implementation of NRC requirements, changes to existing licenses (including license renewals), topical reports, relief requests and new licenses. Reviews and evaluates the design, fabrication, inspection, and repair of mechanical and electrical equipment, instrumentation and controls (analog and digital), and components. Provides technical expertise for issues in the following: Electrical Engineering, Instrumentation and Controls (Analog and Digital), Civil Engineering, Mechanical Engineering, Structural Engineering, and Inservice Testing. Acts as technical liaison with international counterparts, standards committees, and external stakeholders from industry and the public.

Division of Risk Assessment

Director: Michael Franovich
Deputy Director: Russell Felts

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.

Division of Inspection and Regional Support

Director: Christopher Miller
Deputy Director: Gregory Bowman

DIRS is responsible for leading, guiding and coordinating the activities associated with inspecting and assessing licensee performance at commercial nuclear power plants, vendors and new reactors; evaluating plant events and communicating lessons learned to cognizant groups; administering the operator licensing programs; evaluating human factors safety and security issues by conducting licensing reviews of the human factors engineering and organizational structure, and supporting rulemaking, policy development and implementation, and the development and implementation of program documents concerning human factors engineering; and project managing the development and issuance of generic communications.

Division of Licensing Projects

Director: Louise Lund
Deputy Director: MaryJane (MJ) Ross-Lee

Responsible for a diverse set of activities associated with the oversight and licensing of research and test (non-power) reactors, beyond-design-basis event assessment and management, multiple financial qualification aspects of nuclear power plant regulation, licensing processes, such as topical reports, and other special support services. Serves as point-of-contact and provides an overall liaison with vendors, owner's groups, the Nuclear Energy Institute, and the Electric Power Research Institute. Develops processes for, and provides the interoffice interface function with RES, NSIR, NMSS, and NRO; for NRR Continuity of Operations activities, and other special projects of critical importance to the NRC.
