Schematic GE BWR inside a Mark I containment. General Electric's BWR product line of boiling water reactors represents the designs of a relatively large (~18%) [1] percentage of the commercial fission reactors around the world. The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October 1957.
A boiling water reactor (BWR) is a type of nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR).
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
Grand Gulf Nuclear Station is a nuclear power station with one operational GE BWR reactor (General Electric boiling water reactor). It lies on a 2,100 acres (850 ha) site near Port Gibson, Mississippi. The site is wooded and contains two lakes. The plant has a 520-foot natural draft cooling tower. As of January 2023, the plant employs 675 people.
The rods may have the form of tubes filled with neutron-absorbing pellets or powder. The tubes can be made of stainless steel or other "neutron window" materials such as zirconium, chromium, silicon carbide, or cubic 11 B 15 N (cubic boron nitride). [3] The burnup of "burnable poison" isotopes also limits lifespan of a control rod. They may be ...
In 1997, the GE-Hitachi U.S. Advanced boiling water reactor (ABWR) design was certified as a final design in final form by the U.S. Nuclear Regulatory Commission. [4] GE and Hitachi officially established the GE Hitachi Nuclear Energy (GEH) global alliance in 2007 by combining parts of their respective power businesses.
The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor. The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba. The ABWR generates electrical power by using steam to power a turbine connected to a generator; the steam is boiled from water using heat generated by fission reactions within nuclear ...
Unit 1 is a 1,256 MWe net BWR/4 built by General Electric. Construction started on Unit 1 on September 12, 1966 [2] and first powered up for testing on December 20, 1973. Commercial operation began on August 1, 1974. [14] It was licensed to operate through December 20, 2013. [15] Unit 1 was shut down for a year after a fire in 1975 damaged the ...
