The principal objectives of the study were to develop the preliminary design for a 600,000 DWT nuclear powered ULCC, perform ship safety analyses, develop a preliminary quality assurance program, develop a ship construction schedule of key events, develop the shipyard/reactor manufacturer scope of supply, define the interfaces specifically related to the nuclear propulsion plant. In terms of budgetary estimates, an economic evaluation was performed for ship construction cost, ship refueling and drydocking cost, first of a kind ship construction cost, ship manning cost, and contingencies
