Data

On this page:

The Open Government Directive defines high-value information as "information that can be used to increase agency accountability and responsiveness; improve public knowledge of the agency and its operations; further the core mission of the agency; create economic opportunity or respond to need and demand as identified through public consultation." As a regulatory agency whose processes and decisions are captured primarily in the form of documents, the NRC views its documents as its highest value data and has, up until now, focused the thrust of its public information dissemination program in this area. The agency has made its documents available in widely used format for the public's view.

NRC's High-Value Datasets

A list of full-scale Federal Emergency Management Agency (FEMA) and NRC evaluated exercises required of nuclear facilities is provided. The list includes identification of the date and type of exercise (e.g., plume, ingestion, partial), and the participants. NRC Headquarters and Regional staff members typically participate in four full-scale emergency response plume exercises each year and also participate in select ingestion exposure exercises. Exercise participants may include licensee, State, county and local governmental and emergency response agencies, NRC, FEMA and other appropriate Federal agencies.

Foundations for Evidence-Based Policymaking Act of 2018

On January 14, 2019, the President signed in to law H.R. 4174, the "Foundations for Evidence-Based Policymaking Act of 2018" (Public Law 115-435) (the Act). The Act requires federal agencies to take various steps to enhance federal data and evidence-building functions. In support of its goals, the Act requires the designation of a Chief Data Officer (CDO), the Evaluation Officer (EO), and the Statistical Official (SO). Below are the designations of these key positions at the NRC.

In September 2019, the NRC established a Data Governance Board (DGB) that is comprised of senior-level staff to ensure that the NRC is setting priorities for managing data as a strategic asset in service to the agency's mission. The DGB is chaired by the NRC's CDO and meets on a quarterly basis or as often as necessary. Additional information can be found in the charter established for the DGB.

Datasets from the NRC Information Digest

The U.S. Nuclear Regulatory Commission (NRC) has published the Information Digest annually since 1989. Beginning with Volume 34, the Digest began a 2-year publication cycle. The Digest provides information about agency activities and licensees from the various industries it regulates. It describes the agency’s responsibilities and activities and provides general information on nuclear-related topics. It includes NRC and industry data in an easy-to-read format. The datasets listed below are updated after publication of the Information Digest, and are also available in the NRC reading room.

Demographic data on U.S. commercial nuclear power reactors for which licensing activities have been canceled. The available data include plant name/unit number, utility, location, containment type, capacity, cancellation date, and current status.

NRC Data Strategy

The management and use of data are the collective responsibility of all agency staff in carrying out a wide range of programs and functions. Though data may be captured and created locally, its value to the agency can be derived in innumerable ways through data analytics, data science, and data-driven methodologies. It is therefore the vision of the NRC that "data empowers the enterprise" in that it provides the means and the opportunities to execute the agency's mission and to enable continuous improvement along the way.
