Water reactors use water as both a cooling fluid, and a neutron moderator. They have a negative void coefficient. but as positive moderator coefficient of reactivity. Pressurized water reactors are made from multiple components that include, the reactor, primary coolant loop, primary water pump, and steam generator. PWR technology was developed by the Westinghouse company. Hot water may be corrosive to the metal cladding on the fuel, therefore materials such as zirconium resist corrosion. A pressurized water reactor limits the temperature by providing pressure to prevent boiling. These need high-pressure vessels, as well as piping and heat exchangers. Expensive neutron moderator are not needed. PWR reactors allow for a small reactor core for a given power level.[^4] 98.4% of the nuclear reactors in the world are PWRs.[^5]
