Zion Illinois was the site of the Zion Nuclear Power Plant — two nuclear reactors on Lake Michigan that operated from 1973 to 1997 and are currently being decommissioned. The site still contains spent nuclear fuel in dry cask storage. Lake County's position on Lake Michigan creates flooding and storm risk. The proximity to Naval Station Great Lakes and the decommissioning nuclear site creates unique emergency planning requirements for this Lake County community.
