Radiological Emergency Preparedness

FEMA coordinates the national effort to provide state, local and tribal governments with relevant and executable radiological emergency preparedness planning, training, and exercise guidance. We also help set policies necessary to ensure that adequate capabilities exist to prevent, protect against, mitigate the effects of, respond to and recover from incidents involving commercial nuclear power plants.

About PrepToolkit

The Preparedness Toolkit (PrepToolkit) is an online collaborative environment in which individuals from all levels of government and the private and nonprofit sectors can prepare for risks in their communities. It serves as a platform for technology toolkits aligned to each area of the National Preparedness System.

The PrepToolkit provides an avenue to execute preparedness activities efficiently and easily and to share this work with others.

PrepToolkit is a secure, role-based system that is accessible over any internet connection. 

The Validating Capabilities (exercises) component is an IT platform for whole communities that supports implementation of HSEEP and aid exercise planners regardless of the threat/hazard type:

  • Program Management
  • Design & Development
  • Conduct
  • Evaluation
  • Improvement Planning

Radiological Emergency Preparedness (REP) National Public Information Map

An open source national interactive mapping application that connects and informs users to State, Local, Tribal Territorial & Federal radiological preparedness resources (FEMA Public ArcGIS Online) overlay with hazard, demographic & specific REP information.

The REPP PIM consolidates information and data from numerous public resources into one common picture and presents as a preparedness tool that can help strengthen our future community planning and decisions in emergency management.

About the Radiological Emergency Preparedness Program

Nearly three million people live within 10 miles of an operating nuclear power plant. In 2021, there were 56 commercial nuclear power plants in 29 states producing approximately 20 percent of the nation’s power.

To help ensure that the health and safety of people living around commercial nuclear power plants would be adequately protected in the event of a nuclear power plant accident, FEMA established the Radiological Emergency Preparedness (REP) program, through which the agency:

  • Educates the residents in the neighboring communities about what they need to do to prepare for the possibility of a nuclear power plant accident, which would emit dangerous levels of radiation.
  • Coordinates the national effort to provide state, local, and tribal governments with planning, training, and exercise guidance and policies to increase their capability to prevent, protect against, mitigate the effects of, respond to, and recover from commercial nuclear power plant incidents.
  • Evaluates the emergency plans and level of preparedness of state, local and tribal governments, applicants, and licensees to respond to a nuclear accident within the emergency planning zones surrounding, and outside and beyond the boundaries of, a nuclear power plant.

The 2022 Annual Report and 2021 Annual Report provide an overview of the program, showcases significant accomplishments, and highlights the engagement and impact of the program within REP communities. In addition, this report summarizes what the REP Program brings to the emergency preparedness community as it continues to evolve, as well as provides examples of strong relationships, collaborative efforts and impacts on all hazards from the local level.

Federal Radiological Preparedness Coordinating Committee

The Federal Radiological Preparedness Coordinating Committee (FRPCC) is a national-level forum for the development and coordination of radiological prevention and preparedness policies and procedures. It also provides policy guidance for federal radiological incident management activities in support of state, tribal and local government radiological emergency planning and preparedness activities. The FRPCC is an interagency body consisting of the coordinating and cooperating agencies discussed in this Nuclear/Radiological Incident Annex (NRIA), chaired by DHS/FEMA.
