GEH begins licensing process for BWRX-300 SMR

07 February 2020

GE Hitachi Nuclear Energy (GEH) recently announced that it has officially begun the regulatory licensing process for its BWRX-300 small modular reactor.

The BWRX-300 is a 300 MWe water-cooled, natural circulation SMR with passive safety systems that leverages the design and licensing basis of GEH’s U.S. NRC-certified ESBWR. Through dramatic design simplification, GEH projects the BWRX-300 will require significantly less capital cost per MW when compared to other water-cooled SMR designs or existing large nuclear reactor designs.

By leveraging the existing ESBWR design certification, utilizing licensed and proven nuclear fuel designs, incorporating proven components and supply chains and implementing simplification innovations the BWRX-300 can, GEH believes, become cost-competitive with power generation from combined cycle gas plants and renewable energy platforms.

As the tenth evolution of GE’s first Boiling Water Reactor (BWR) design, GEH’s BWRX-300 represents the simplest, yet most innovative BWR design.
