// Strategic Significance
Byron Nuclear Station in Ogle County operates two reactors on the Rock River in northern Illinois. It is part of Exelon's massive Illinois nuclear fleet which provides over half the state's electricity. The Rock River downstream of the plant flows toward the Mississippi River system. Byron sits in a region of significant agricultural production.
// Civilian Impact Assessment
The 50-mile ingestion zone from Byron reaches the Rockford metropolitan area and extends toward Chicago's western suburbs. The Rock River below the plant supplies water to downstream communities. Agricultural operations in the fertile Illinois farmland within the ingestion zone would face food safety restrictions during any significant release.
// Evacuation & Shelter Guidance
10-mile EPZ: Evacuate via IL-2 or US-20. Monitor Illinois Emergency Management Agency broadcasts. 50-mile zone: Rockford area residents monitor IEMA guidance. Avoid Rock River fish consumption during any release event.
