// Strategic Significance
Callaway Nuclear Plant is Missouri's only nuclear power plant generating approximately 12% of the state's electricity. Located in central Missouri between Columbia and Jefferson City it supplies power to much of the state. The plant sits on the Missouri River — the longest river in the United States — raising contamination concerns for the downstream Missouri-Mississippi river system in the event of a major release.
// Civilian Impact Assessment
The 50-mile ingestion zone from Callaway encompasses Jefferson City the state capital and Columbia home to the University of Missouri. The Missouri River downstream of the plant flows through Kansas City and eventually joins the Mississippi. Any significant water release could affect drinking water sources for millions across Missouri.
// Evacuation & Shelter Guidance
10-mile EPZ: Evacuate via US-54 east or west away from Callaway County. Monitor Missouri State Emergency Management Agency broadcasts. 50-mile zone: Jefferson City and Columbia residents monitor SEMA guidance. Avoid Missouri River fish and water recreation during any event. Columbia area residents near University of Missouri monitor institutional emergency communications.
