Nuclear submarines can operate underwater for three or four months in a row and cross oceans with ease. While some conventional submarines can withstand distance, none have comparable submarine resistance. Navy nuclear submarines can remain submerged for long periods of time. Air is not a problem, as they produce their own oxygen and keep the air clean.
The limits for how long they can stay underwater are food and supplies. Submarines generally have a 90-day supply of food, so they can spend three months underwater. While AIP ships may not be able to accomplish everything a nuclear submarine can achieve, having a huge fleet of submarines to chase rival ships and submarines for dominance of the seas can be very beneficial. Naval Nuclear Transportation Oregon Department of Energy This webpage provides information on transporting decommissioned naval nuclear reactors.
Washington State Nuclear Waste, Department of Ecology This site provides information on the Hanford program and other Washington State nuclear waste programs. The Nuclear Waste Program of the Washington State Department of Ecology works to oversee all Hanford nuclear waste activities. Some of the submarines and aircraft carriers in the United States fleet are powered by nuclear reactors. The Department of Energy (DOE) discards some types of contaminated reactor parts from nuclear ships at the Hanford facility in Washington State.
The main difference between conventional submarines and nuclear submarines is the power generation system. Nuclear power proved to be ideal for the propulsion of strategic ballistic missile (SSB) submarines, greatly improving their ability to remain submerged and undetected. The United States maintains 14 nuclear-powered Ohio-class ballistic missile submarines to serve as the maritime stretch of the American nuclear triad. The construction of the world's first nuclear submarine was made possible by the successful development of a nuclear propulsion plant by a group of scientists and engineers from the United States in the Naval Reactor Branch of the Bureau of Ships and the Atomic Energy Commission.
That certainty means that a nation planning a first-strike nuclear attack can be sure that the United States will respond with its own nuclear weapons in kind. The Oregon Department of Energy works with the Navy to ensure the safe passage of barges carrying nuclear waste. Since World War II, nuclear-powered submarines have played a strategic role in the nuclear triad throughout the Cold War, as well as tactically in the War on Terrorism with highly advanced weapon systems. From the late 1950s to the end of 1997, the Soviet Union, and later Russia, built a total of 245 nuclear submarines, more than all other nations combined.
The most excellent dive speed of the German Type 214 is the standard of AIP submarines, at 23 mph (37 km/h). The USS Carl Vinson, an aircraft carrier powered by two nuclear reactors, is docked near San Diego, California.
