Inhm and Option for CongHỊt Summary Some Members of Congress particularly on the I louse Al med Sen ices Coinmilice. have expressed interest in expanding he use of nuclear power Co a wider array of Navy surface ships. Including the Na y s planned CG X I cruiser. Section 1012 of the FY2II0K defense authorization act H.R 4986 P.L. ỉ 10-181 of January 28. 2008 makes it U.S. policy to construct the major combatant ship of he Navy including the C itX.1. with integrated nuclear power systems unless the Secretary of Defense submits a notification to Congress that the inclusion of an integrated nuclear power system in a given class of vhip is not in the national interest. The Navy has studied nuclear power as a design option for the CG X . Inn has not yet announced whether It would prefer to build the CGí X as a nuclear-powered ship. The Navy s proposed I Y20H1 budget defers the planned procurement of the first CG X from I Y2011 the scheduled dale under the FY2O09 budget to a year beyond IY2OI5 moM likely FY20I7. A2006 Navy study concluded the following among other things In constant I Y20O7 dollars building a Navy surface combatant or amphibious ship with nuclear power Hither han conventional power would add roughly 600 million to 800 million io its pniiurcrmni cost. The total life-cycle cost of a nuclear-powered medium-size surface combatant would equal that of a conventionally powered medium-size surface combatant it thè cost of etude oil averages 70 per barrel to 225 per barrel over the life of the ship. Nuclear-power should be considered for near-term applications for medium-size surface combatants. Compared to conventionally powered ships .
