Steam from the nuclear reactor turns turbines. These turbines either turn the propeller directly or turn generators that produce electricity to power electric motors which turn the propellor.
Nuclear power is used to create large amounts of heat which generate steam. Basically, the steam is then used to spin steam turbines attached to generator sets, which generate power.
They typically run on steam power, using nuclear reactors to create the steam. Prior to the development of the nuclear power systems, they used electric motors through batteries, that were charged using diesel engines. On the surface the diesel also propelled the shafts.
Heat from the nuclear reaction changes water to steam.
The key to the range and duration of the modern nuclear submarine is the nuclear reactor. The reactor generates heat through nuclear fission, and this does not use air (or the oxygen in it). The heat is used to make steam, and the steam drives conventional steam turbines. With a large power source and no requirement to be on the surface, the boats can stay down for an extended period limited only by the amount of provisions they can stow aboard prior to deployment.
Actually, superheated steam is used in nuclear power plants. It is part of the goal of extracting the most energy possible from the steam cycle.
The Navy uses Nuclear Power to create steam. Steam is then used to power steam turbines, which in turn power the ship's screws and generators. The US Navy has steam plants, gas turbines, diesel and nuclear powered vessels.
Steam in nuclear power plants is used to drive turbines for generation of kinetic energy.
Heat from the nuclear reaction changes water to steam.
Nuclear reactors produce heat, the heat then is used to make steam, turning turbines. Therefore, the waste of a nuclear power plant is excess steam.
Sorry, but that information is classified.
The steam turbines (which use the steam produced by the hot nuclear pile).
It is used for electricity in nuclear power plants == == Nuclear power is used to heat steam which then turns turbines, which generate electricity in nuclear power stations and also to provide propulsion and power on board nuclear submarines.
