Pressurized water reactors, like all thermal reactor designs, require the fast fission neutrons to be slowed (a process called moderation or thermalizing) in order to interact with the nuclear fuel and sustain the chain reaction. Water in the reactor core reaches about 325°C, hence it must be kept under about 150 times atmospheric pressure to prevent it boiling. This is a cheap and simple reactor.

Boiling Water Reactor History and Line-UP Simple & Reliable Nuclear-Power Generation System One of the world's most common types of nuclear power generating plants, boiling water reactors, are characterized by a system wherein steam generated inside the reactor is directly passed to the turbine to simplify the process and equipment. Construction and working principle of Boiling Water Reactor (BWR) Figure shows a simplified BWR. A boiling water reactor (BWR) uses steam generated in the reactor to directly supply the turbine, unlike a pressurized water reactor (PWR) that has steam generators where the steam is generated. In the PWR, water at high pressure and temperature removes heat from the core and is transported to a steam generator. In boiling water nuclear reactors (BWRs), the heat generated by the splitting of uranium atoms is used to boil water within the reactor … Light-water reactors (LWRs) are power reactors that are cooled and moderated with ordinary water.There are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). Pressure . Boiling water reactor boils light water that is fed to the reactor. Modern boiling water reactors (BWRs) have no steam generators, so that the reactor coolant system is more compact than that of pressurized water reactors (PWRs).The containment building can be correspondingly smaller. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. English: Diagram of a typical Boiling water reactor (BWR) Mark I Concrete Containment with Steel Torus, as used in the BWR/1, BWR/2, BWR/3 and some BWR/4 model reactors.

Diagram of the workings of a boiling water reactor (BWR), a type of nuclear reactor. Boiling Water Reactors. A boiling water reactor (BWR) is a type of light-water nuclear reactor developed by the General Electric Company in the mid 1950s. This large amount of heat is absorbed by the coolant and it is circulated through the core. The resulting steam is generally used directly to drive a turbine. These reactors signify about 12% of the nuclear reactors globally. Power reactors Light-water reactors PWRs and BWRs. The steam passes through a condenser, which uses water from a cooling pond (lower right), before being passed back into the reactor chamber. Example: Nuclear Power … In the primary cooling circuit the water is also the moderator, and if any of it turned to steam the fission reaction would slow down. This turns a turbine, which drives an electricity generator (white). Training Course Series No. Schematic diagram of a boiling water reactor (BWR) - German only Source: Deutsches Atomforum e. V..
