Radiological Emergency Preparedness Program

About the REP Program

Four different nuclear power plants

The Indiana Department of Homeland Security’s (IDHS) Radiological Emergency Preparedness (REP) Program coordinates efforts to protect and respond to incidents involving commercial nuclear power plants. The REP Program provides the state of Indiana and local communities with plans, training and guidance related to nuclear energy incidents. The program follows federal guidance and policies to ensure capabilities exist to prevent, protect against, mitigate the effects of and respond to and recover from incidents involving nuclear power plants.

Ingestion Pathway Preparation and Planning

Eleven Indiana counties are within the Ingestion Pathway Zone of four commercial nuclear power plants (two in Michigan and two in Illinois).

Each nuclear power plant’s Ingestion Pathway Zone is a 50-mile radius. This 50-mile radius requires specialized emergency planning. IDHS provides guidance and policies to ensure state, local and tribal governments have adequate capabilities to protect, respond to and recover from incidents involving commercial licensed nuclear power plants. The Nuclear Regulatory Commission (NRC) is responsible for the on-site emergency preparedness at all U.S. nuclear power plants. The Federal Emergency Management Agency (FEMA) has the lead role with off-site emergency planning and preparedness.
