High Quality Content by WIKIPEDIA articles! Nuclear propulsion includes a wide variety of propulsion methods that use some form of nuclear reaction as their primary power source. Many military submarines, and, owing to crude oil prices and emissions, aircraft carriers and a growing number of large civilian surface ships, especially icebreakers, use nuclear reactors as their power plants (see nuclear marine propulsion for civil use and nuclear navy for military use). In addition, various types of nuclear propulsion have been proposed, and some of them tested. Anatolij Perminov, head of Russian Space Agency announced that RKA is going to develop a nuclear powered spacecraft for deep space travel. Design will be done by 2012, and 9 more years for development (in space assembly). The price is set to 17 billion rubles (600 million dollars).
