ABSTRACT (Maximum 200 words) The Maritime Administration owns and maintains the Nuclear Ship Savannah (NSS), the world’s first nuclear powered merchant ship. The NSS was powered by a pressurized water reactor (PWR) that was originally operated from 1962 to 1970, after which it was deactivated, defueled and partially decontaminated in accordance with the best practices of the day. In 2002, the Agency decided to re-evaluate its circa 1975 long-range decommissioning plan. Therefore, a planning process was initiated to determine the preferred end use of the vessel as well as consideration given for the decontamination and disposal of the remaining low-level radioactive material. The Agency has proposed to prepare the NSS for decommissioning, i.e. final nuclear decontamination, and is using the NEPA process to evaluate potential impacts of the alternatives. At this stage of the planning process, MARAD will be conducting an analysis of the proposed decommissioning of the NSS. Therefore, MARAD has decided to prepare an Environmental Assessment (EA), in accordance with the requirements of the NEPA, as amended (P.L. 91-190). 14. SUBJECT TERMS 15.
