1Title:  Draft environmental assessment on the disposal of naval reactors plants from USS Enterprise (CVN-65) Add
 Summary:  This document provides information on the preferred disposal plan for the eight defueled reactor plants in the USS Enterprise, the world's first nuclear-powered aircraft carrier. It lays out the timeline for Enterprise's deactivation; it "is expected to enter dry dock at Newport News Shipbuilding in Virginia for inactivation in 2013. Defueling will be conducted at Newport News Shipbuilding. Inactivation is expected to be complete in about 2017 or 2018" (1-1). At that point, Enterprise will be towed to the Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF) for removal of the already-defueled reactor compartments. The compartments will be packaged and shipped to the Department of Energy's Hanford Site. The actual shipment of the packages to Hanford is estimated to occur between 2023 and 2027. The assessment includes information on the estimated exposure required for the preparation and packaging of the compartments (about 300 rem of collective radiation exposure") (2-2). Page 2-6 includes a diagram that shows the locations of the eight reactor compartments on board the Enterprise, which are paired in four propulsion plants. The assessment describes the methodology for transporting the packages to Hanford and describes transport challenges and accident scenarios. The document also describes an interim "no-action alternative" to the preferred plan: placing the Enterprise in waterborne storage at the PSNS & IMF facility. This alternative has the disadvantage of "only delay[ing] ultimate permanent disposal" (2-17).
