// Strategic Significance
Sequoyah Nuclear Plant on Chickamauga Lake north of Chattanooga operates two pressurized-water reactors as part of TVA's nuclear fleet. The plant sits on the Tennessee River system which flows through multiple states. Chattanooga is within the 10-mile emergency planning zone making Sequoyah one of the nuclear plants closest to a major urban center in the TVA region.
// Civilian Impact Assessment
Chattanooga Tennessee sits within or very near the 10-mile EPZ of Sequoyah making it one of the US nuclear plants with the largest city directly in its emergency planning zone. The Tennessee River downstream supplies water and supports recreation across multiple states. The 50-mile ingestion zone encompasses portions of northern Georgia and northeastern Alabama.
// Evacuation & Shelter Guidance
10-mile EPZ: Chattanooga residents in the EPZ evacuate immediately via I-75 or US-27. Monitor Tennessee Emergency Management Agency broadcasts. 50-mile zone: Northern Georgia and northeast Alabama residents monitor TEMA and Georgia GEMA guidance. Chickamauga Lake and Tennessee River fish consumption restrictions would apply.
