// Strategic Significance
Catawba Nuclear Station on Lake Wylie along the North Carolina-South Carolina border operates two reactors and is part of Duke Energy's Carolinas nuclear fleet alongside McGuire Nuclear Station in North Carolina. The Catawba River system below the plant flows through South Carolina supplying water to communities downstream. Charlotte NC is within the 50-mile ingestion zone.
// Civilian Impact Assessment
The Charlotte North Carolina metro area falls within Catawba's 50-mile ingestion zone overlapping with McGuire Nuclear Station's zone creating a region with two nuclear plants and one major metro. The Catawba-Wateree River system below the plant supplies water to communities downstream through South Carolina to the coast.
// Evacuation & Shelter Guidance
10-mile EPZ: Evacuate via SC-274 or SC-49. Monitor South Carolina Emergency Management Division broadcasts. 50-mile zone: Charlotte area and Rock Hill SC residents monitor SCEMD and NC EM guidance. Catawba River fish and water recreation restrictions would apply. Lake Wylie recreational activities would be immediately restricted.
