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.
Final rule was issued on September 16, 2014, after two outstanding problems with GE-Hitachi's modeling of loads on the steam dryer were solved. [8] [9] In January 2014, GE Hitachi paid $2.7 million to resolve a lawsuit alleging it made false claims to the NRC about its analysis of the steam dryer. [10] The NRC granted design approval in ...
Slightly different versions of the ABWR are offered by GE-Hitachi, Hitachi-GE, and Toshiba. [5]In 1997 the GE-Hitachi U.S. ABWR design was certified as a final design in final form by the U.S. Nuclear Regulatory Commission, meaning that its performance, efficiency, output, and safety have already been verified, making it bureaucratically easier to build it rather than a non-certified design.
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 ...
The BWR concept was developed slightly later than the PWR concept. Development of the BWR started in the early 1950s, and was a collaboration between General Electric (GE) and several US national laboratories. Research into nuclear power in the US was led by the three military services.
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 BWRX-300 is a smaller evolution of an earlier GE Hitachi reactor design, note the Economic Simplified Boiling Water Reactor (ESBWR) design and utilizing components of the operational Advanced boiling water reactor (ABWR) reactor. [1] Boiling water reactors are nuclear technology that use ordinary light water as a nuclear reactor coolant ...
