The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October 1957. Six design iterations, BWR-1 through BWR-6, were introduced between 1955 and 1972. This was followed by the Advanced Boiling Water Reactor (ABWR) introduced in the 1990s and the Economic Simplified Boiling Water Reactor (ESBWR ...
An animation of a BWR power station with cooling towers. A boiling water reactor (BWR) is a type of nuclear reactor used for the generation of electrical power.
English: Nuclear reactor: boiling water type. Water is heated through the controlled splitting of uranium atoms in the reactor core and turns to steam. Pumps force the water through the reactor at top speed, maximizing steam production. Steam drives the turbines that turn the generator that makes electricity.
LWRs can be subdivided into three categories – pressurized water reactors (PWRs), boiling water reactors (BWRs), and supercritical water reactors . The SCWR remains hypothetical as of 2009; it is a Generation IV design that is still a light-water reactor, but it is only partially moderated by light water and exhibits certain characteristics ...
The Vallecitos boiling water reactor (VBWR) was the first privately owned and operated nuclear power plant to deliver significant quantities of electricity to a public utility grid. During the period October 1957 to December 1963, it delivered approximately 40,000 megawatt-hours of electricity.
Boiling water reactors are nuclear technology that use ordinary light water as a nuclear reactor coolant. Like most boiling water reactors, the BWRX-300 will use low pressure water to remove heat from the core. A distinct feature of this reactor design is that water is circulated within the core by natural circulation. This is in contrast to ...
Water is heated through the splitting of uranium atoms in the reactor core. The water, held under high pressure to keep it from boiling, produces steam by transferring heat to a secondary source of water. The steam is used to generate electricity. Cooling water from the river condenses the steam back into water.
Units B and C are, like unit A, boiling water reactors. In this type of reactor, the water flows around the fuel elements, boils, and the steam directly drives the turbines. Thus, in boiling water reactors, in contrast to pressurized water reactors, there is only a single, primary coolant loop. Each unit is loaded with 784 fuel elements.
