Core (typically uranium) creates heat that makes steam that turns turbines to make electricity. This is simply a pressure vessel with an electric heating coil at the bottom and a water spray at the top.
The leftover water from the main condenser is recycled back to the stem generator.
Pressurized water reactor employs a closed loop of pressurized water that delivers heat to the steam generator and steam cycle. The boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. Pressurised Water Reactor(PWR) • PWR is the most common type of nuclear reactor, representing about 60% of all nuclear power reactors in the world.  The reactor converts heat (that is generated into fuel) into electrical power. Pressurized water reactors have advantages over the other light water reactors and earlier generation nuclear sites. This water also slows down (or moderates) neutrons (constituents of atom nuclei that are released in the nuclear fission process). Pressurized water reactor (PRW) Nuclear fission produces heat inside the reactor. The Pressurized Water Reactor (PWR) The Pressurized Water Reactor (PWR) PWRs keep water under pressure so that it heats, but does not boil. The pressurized water reactor is commonly used in nuclear power plants over the world. A pressurized water reactor (PWR) is a type of power plant reactor consisting of two basic circuits having light water as the working fluid. In a Pressurised Water Reactor (PWR) like the EPR™ reactor, ordinary (light) water is utilized to remove the heat produced inside the reactor core by nuclear fission. They are cooled and moderated by high-pressure liquid water (e.g. Pressurized water reactors use a reactor pressure vessel (RPV) to contain the nuclear fuel, moderator, control rods and coolant.
The uranium decays into different elements following the uranium It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor. See also: Pressurized Water Reactors Page The reactor vessel of a pressurized water reactor (PWR) power plant contains the nuclear core and requires the utmost reliability, to ensure safe use under extremely harsh conditions including high temperature, high pressure, and neutron exposure. • Water from the reactor and the water in the steam generator that is turned into steam never mix. This water also slows down (or moderates) neutrons (constituents of atom nuclei that are released in the nuclear fission process). This power can be used for industrial and residential purposes. The water is heated to extremely high temperatures, but doesn’t boil because the water … In the PWR, water at high pressure and temperature removes heat from the core and is transported to a steam generator.
