  A nuclear reactor produces heat that drives a steam turbine, which in turn drives a propeller. There are three main types of marine reactors: pressurized water reactors, natural circulation reactors, and liquid metal reactors.   Typically, uranium produces heat in a nuclear reactor by nuclear fission of submarine . In a nuclear reactor, the uranium is surrounded by a moderator, which is required to slow down the reacting neutrons so that they can interact with the uranium more efficiently. In most reactors, the moderator is water, which is also used to remove the heat of reaction. This heated water is called the primary circuit water. The water, which is under pressure to prevent boiling, flows through a heat exchanger where the heat is transferred to a separate secondary water circuit. The heat exchanger is essentially a boiler, and the secondary circuit or loop actually provides the steam that drives the turbine. As long as proper seals are ensured, water from the prim...
