Most of the plants in operation are light water reactors, meaning they use normal water in the core of the reactor. Different reactor technologies are in use abroad, such as the heavy water reactors in Canada. U.S. reactors account for more than one-fourth of nuclear power capacity in the world.

The Nuclear Reactor processes Uranium-based Reactor Rods into Energy for use by a Seabase. The reactor is constructed with the Habitat Builder, and can only be placed in the centre of a Multipurpose Room. The Nuclear Reactor generates energy at different speeds depending on how many reactor rods are installed. Up to four rods can be installed for maximum power output. It does not affect power in creative mode.

Renewable energy sources will usually be sufficient for maintaining a small outpost. For everything else there's nuclear power. 1  Powered by up to four replaceable uranium reactor rods. 2  Do not attempt to replace reactor rods without a full radiation suit.  Do not attempt to overclock the reactor.

Commercial nuclear power plants range in size from about 60 megawatts for the first generation of plants in the early 1960s, to over 1000 megawatts. Many plants contain more than one reactor. The Palo Verde plant in Arizona, for example, is made up of three separate reactors, each with a capacity of 1,334 megawatts.

How a nuclear reactor makes electricity. A nuclear reactor produces and controls the release of energy from splitting the atoms of uranium. Uranium-fuelled nuclear power is a clean and efficient way of boiling water to make steam which drives turbine generators. Except for the reactor itself, a nuclear power station works like most coal or gas-fired power stations. Several hundred fuel assemblies containing thousands of small pellets of ceramic uranium oxide fuel make up the core of a reactor.

American power plants are using over 40 million pounds of uranium fuel each year. Much more uranium is likely to be available beyond our proven reserves. Uranium comes in two forms, U-235 and U-238. As found in nature, uranium is more than 99 percent U-238; unfortunately, U-235 is what is used in power plants.

Because uranium atoms are so large, the atomic force that binds it together is relatively weak, making uranium good for fission. In nuclear power plants, neutrons collide with uranium atoms, splitting them. This split releases neutrons from the uranium that in turn collide with other atoms, causing a chain reaction.

After the steam is used to power the turbine, it is cooled off to make it condense back into water. Some plants use water from rivers, lakes or the ocean to cool the steam, while others use tall cooling towers. The hourglass-shaped cooling towers are the familiar landmark of many nuclear plants.

1 This nuclear reaction was the first of the two to be discovered. All commercial nuclear power plants in operation use this reaction to generate heat which they turn into electricity.  Fusion is the combining of two small atoms such as Hydrogen or Helium to produce heavier atoms and energy.

Nuclear energy's contribution to global electricity supply. Nuclear energy supplies about 11% of the world's electricity. Today 31 countries use nuclear energy to generate up to three quarters of their electricity, and a substantial number of these depend on it for one-quarter to one-third of their supply.
