// Strategic Significance
Fort Calhoun Nuclear Station north of Omaha permanently closed in 2016 and is undergoing decommissioning. Like Cooper Nuclear it sits on the Missouri River and was surrounded by floodwaters in 2011. Fort Calhoun's closure left Nebraska with only one operating nuclear plant. Spent nuclear fuel remains stored on site and the decommissioning process will take years.
// Civilian Impact Assessment
The Omaha metropolitan area north of Fort Calhoun falls within the 50-mile ingestion zone. The Missouri River at this location flows past Omaha and downstream. Offutt Air Force Base home to US Strategic Command is downstream from Fort Calhoun creating an interesting overlap of nuclear waste storage and nuclear command infrastructure.
// Evacuation & Shelter Guidance
10-mile EPZ: Evacuate via US-75 south toward Omaha or north away from metro area. Monitor Nebraska EMA broadcasts. Decommissioning sites maintain emergency plans for spent fuel storage accidents. Omaha area residents should be aware of both Fort Calhoun decommissioning status and Offutt AFB flood risk as separate emergency planning considerations.
