Pressurized Water Reactor Nuclear Energy Britannica The core inside the reactor vessel creates heat. pressurized water in the primary coolant loop carries the heat to the steam generator. inside the steam generator, heat from the primary coolant loop vaporizes the water in a secondary loop, producing steam. In a pwr, water is used both as a neutron moderator and as coolant fluid for the reactor core. in the core, water is heated by the energy released by the fission of atoms contained in the fuel. using high pressure (around 155 bar: 2250 psi) ensures that the water stays in a liquid state.
Pressurized Water Reactor Diagram Quizlet Hot pressurized water flows to the special heat exchanger called steam generator (a part of an nsss). within this water to water heat exchanger, the coolant transfers heat to the second loop and, being cooled down, is pumped back to the reactor. the first loop is therefore completely closed. The initial circuit, known as the primary loop, circulates the pressurized water directly through the reactor core to absorb heat. this superheated, high pressure water then flows through a steam generator, which acts as a specialized heat exchanger. One aspect of reactor operation concerns what is commonly referred to as core “management”, which is aimed at making the best possible use of fuel. in a pwr, fresh fuel is loaded into the reactor at regular, rather long intervals – between 1 and 2 years. The resulting water is pumped out of the condenser with a series of pumps, reheated, and pumped back to the steam generator. the reactor's core contains fuel assemblies that are cooled by water circulated using electrically powered pumps.

Pressurized water reactor uses enriched u as fuel. in this reactor, water is used as coolant and moderator. the water passes through the reactor core and becomes hot water. the hot water flows to a heat exchanger (steam generator) where its heat is transferred to the feed water to generate steam. The principle of the pressurized water reactor is that the coolant circuit containing light water is pressurized to prevent boiling at the prevailing temperatures. the hot pressurized coolant is then used to generate steam in a secondary circuit at a lower pressure. Which in turn drives generate electricity. the major characteristic of a pwr is that the primary cooling water that comes into direct contact with the fuel rods, and the secondary cooling water that drives the turbines as steam, are completely separated. pwrs are used by hokkaido electric power co., kansai electric power co., c power co., a. Pressurized water reactors (pwr) are generation ii nuclear power reactors that use ordinary water under high pressure as coolant and neutron moderator. the primary coolant loop is kept under high pressure to prevent the water from reaching film boiling, hence the name.
