Nuclear Power Info Tracker | About this Feature

For more than 30 years, UCS has monitored safety levels at U.S. nuclear power reactors and intervened when safety levels drop lower than federal regulations permit. We have found that, all too frequently, a problem found at one reactor is bound to afflict other reactors as well. In addition, a single reactor often has more than one reason for its safety levels being too low. To help put the issue of nuclear power safety on the map-literally-we created Nuclear Power Information Tracker, a comprehensive, interactive resource for information on U.S. nuclear power reactors.

Nuclear Power Information Tracker allows users to search for reactors using various criteria such as location, reactor type, operational status, and safety concerns. It also gives in-depth information about each reactor, including past and present safety issues, UCS letters to the Nuclear Regulatory Commission (NRC), and testimony to Congress. By showing the extent to which unresolved safety problems affect reactors across the country, it is our hope that this interactive feature will help speed up efforts by both reactor operators and the federal government to resolve these safety issues and ensure they never happen again.

How to use the Nuclear Power Information Tracker

  • Hover—You can simply hover over an icon and the reactor name, city, and state will appear with the safety issue icons. 
  • Zoom—In congested areas, such as the northeast, southeast, and midwest, you can zoom in on the area by using the '+' and '–' buttons in the lower left-hand corner of the map.  By clicking on a state at the U.S. map level, you can zoom into that state and the list of reactors for that state appears below the map.  You can also grab the map and move it up, down, left, and right to position the map for zooming.
  • Click on an icon—You can click on an icon and the map will zoom into that county and provide a more detailed popup window with reactor name, city, state, type of reactor, 10-mile population, and safety issue icons.  From here you have the option to go to a web page with in-depth information on your selected reactor.  You can also access the in-depth pages by clicking on "Reactor page" in the list below the map.
  • Use the selection filters—You can use the selection filters on the right-hand panel.  Select the operational status and reactor type from the drop-down menu, then you may choose any number of safety issues by clicking on the check box. To activate the map, click on the "refresh map" button on the bottom of the panel.  This will sort the map according to your selections and place icons on the map that represent each reactor that has all of the selected criteria.  You can now hover and click on icons as described above.  A list of those reactors will also appear below the map where you can  access the in-depth pages by clicking on "Reactor page" in the list below the map.
  • View the complete list—If you want to see the full list of all U.S. nuclear reactors, you can click on the 'List' link in the navigation banner.
  • Define the safety issues—If you want a definition of safety issues, operating status, or reactor types, you can click on the '?' button next to the safety issue.  Once you select an operating status or reactor type, the '?' button will appear.  Or, if you want to see the entire list, you can click on the "Definitions" link in the navigtion banner.
