Pressurized water reactor - Wikipedia
A pressurized water reactor (PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan, India and Canada).

2023年2月9日 · Pressurized Water Reactors. Printable Version. Typical Pressurized-Water Reactor. How Nuclear Reactors Work. In a typical design concept of a commercial PWR, the following process occurs: The core inside the reactor vessel creates heat. Pressurized water in the primary coolant loop carries the heat to the steam generator.
This chapter will discuss the purposes of some of the major systems and components associated with a pressurized water reactor. There are two major systems utilized to convert the heat generated in the fuel into electrical power for industrial and residential use.
Reactor pressure vessel - Wikipedia
Of the main classes of reactor with a pressure vessel, the pressurized water reactor is unique in that the pressure vessel suffers significant neutron irradiation (called fluence) during operation, and may become brittle over time as a result.

Pressurized water reactor: How does a PWR reactor work?
2017年6月16日 · How does a pressurized water reactor work? The pressurized water reactor (PWR) works in 4 steps: The reactor core within the reactor vessel generates heat through fission reactions. The high-pressure water from the primary circuit transports this thermal energy to a steam generator outside the pressure vessel.
Pressurized Water Reactor - an overview | ScienceDirect Topics
Pressurized water reactor employs a closed loop of pressurized water that delivers heat to the steam generator and steam cycle. The operating process in this reactor is quite simple. The pressure vessel contains vertically arranged fuel elements and control rods, which are admitted from the top to control the reaction.
The reference pressurized water reactor (PWR) generating system is a dual cycle plant based on the Westinghouse nuclear steam supply System. It consists of a reactor vessel and up to four closed coolant loops connected in parallel (primary cycle) and a separate power conversion system (secondary cycle).
Pressurized Water Reactor - an overview | ScienceDirect Topics
Water enters the reactor vessel (Fig. 6) at the inlet nozzle, flows downward along the inner vessel wall, is distributed at the lower vessel plate, flows up through the fuel assemblies gaining heat energy, and exits at the outlet nozzle.
