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.

Powered by proven and commercially available fuel, the BWRX-300 features an innovative and simplified configuration, resulting in less concrete and steel needed for construction.

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). BWR are thermal neutron reactors, where water is thus used both as a coolant and as a moderator, slowing down neutrons.

For more than 60 years, GE and Hitachi have configured and built the world’s safest-operating boiling water reactors (BWRs). With their simple yet sound configuration, GEH has developed most of the BWRs currently operating today. Net power generation range. Countries licensed for operation. Reactors currently operating.

Table 6.0-1 has been developed to allow comparisons of various BWR functions for the product lines BWR/2 thi'ough BWR/6. The figures in this chapter illustrate most of the more important differences indicated in the tables.

GE Hitachi Nuclear Energy’s GEH’s BWRX-300 is a designed-to-cost 300 MWe water-cooled natural circulation Small Modular Reactor (SMR) utilizing simple natural phenomena-driven safety systems. It is the tenth generation of the Boiling Water …

This chapter will discuss the purposes of some of the major systems and components associated with a boiling water reactor (BWR) in the generation of electrical power. Inside the boiling water reactor (BWR) vessel, a steam water mixture is produced when very pure water (reactor coolant) moves upward through the core absorbing heat.

The BWRX-300 is a design for a small modular nuclear reactor proposed by GE Hitachi Nuclear Energy (GEH). The BWRX-300 would feature passive safety, in that neither external power nor operator action would be required to maintain a safe state, even in extreme circumstances.

“BWR/6: General Description of a BWR,” GE, 1980. Why are the fuel rods spaced out more in a BWR than in a PWR? Why is the core power density lower in a BWR core than in a PWR? What is the purpose of spatial fuel enrichment zoning throughout a BWR fuel assembly? What function do the water rods perform?
