Nuclear Sites Map

DOE nuclear operations are mostly divided between nuclear weapons stockpile maintenance, research and environmental cleanup. The operations are performed within several different facilities supporting nuclear reactor operations, nuclear research, weapons disassembly, maintenance and testing, hot cell operations, nuclear material storage and processing and waste disposal. Each nuclear facility is characterized by the level of hazard they present to the public and workers from the amount and type of nuclear materials present at the facility.

• Hazard Category 1 is assigned to the most hazardous facilities, for example nuclear reactors, that could have a significant impact on the public;
• Hazard Category 2 is assigned when the potential safety impact is to workers within a site boundary; and
• Hazard Category 3 is assigned to the least hazardous facilities where the potential safety impact is to workers within a facility.
