The Technological Hazards Division's Radiological Emergency Preparedness Program has developed and maintained a suite of interactive decision support tools that provide the public and REP community with public authoritative information about operating Nuclear Power Plants (NPPs) from the Nuclear Regulatory Commission and the US Department of Energy's Energy Information Administration. These tools help to centralize relevant and otherwise disaggregate REP information sources from Federal and state, local, tribal, and territorial partners in a single national view for users to explore, understand and learn more about radiological emergency preparedness.

Use the interactive map below to explore the REPP Public Information Map and the Community Nuclear Power Plant Status App.

REPP Data Sources

The interactive maps above contain a large number of authoritative and best available data sources that help support decision making around radiological emergency preparedness. Provided below are a few key data sources for reference:

• REPP Data Layers - This data layers reference document provides additional information on the REPP PIM and resource links. The data layers are categorized into Critical Public Facilities, Hazard and Weather Data, Demographic Data, Radiological Data, and FEMA Operational data.
• Active CSEPP Locations - Identifies the general locations of the current and active U.S. Chemical Stockpile under the Chemical Stockpile Emergency Preparedness Program (CSEPP).
• EPA Radiation Monitors - RadNet has 140 radiation air monitors in 50 states and runs 24 hours a day, 7 days a week collecting near-real-time measurements of gamma radiation
• Operating Nuclear Power Plant Sites by Output (MWe) - Status of US Nuclear Outages based on data from U.S. Energy Information Administration (EIA).
• Nuclear Power Plant Reactor Power Status - Nuclear Plant Power Reactor Status provided by Nuclear Regulatory Commission (NRC). Daily NRC Demographic D
