Cameco Corporation, GE Hitachi Nuclear Energy (GEH), GEH SMR Technologies Canada Ltd. (GEH SMR Canada) and Synthos Green Energy (SGE), have entered into a Memorandum of Understanding (MOU) to evaluate the potential establishment of a uranium fuel supply chain in Canada capable of servicing a potential fleet of BWRX-300 small modular reactors (SMRs) in Poland. Synthos, a manufacturer of synthetic rubber and one of the biggest producers of chemical raw materials in Poland, is interested in obtaining affordable, on-demand, carbon-free electricity from a dependable, dedicated source. In 2019 SGE and GEH agreed to collaborate on potential deployment applications for the BWRX-300 in Poland. SGE and GEH signed a strategic agreement in 2020 that further advanced the cooperation. Cameco supplies uranium, uranium refining and conversion services to the nuclear industry worldwide. In July 2021, Cameco, GEH and Global Nuclear Fuel-Americas (GNF-A) agreed to explore several areas of cooperation to advance the commercialization and deployment of BWRX-300 SMRs in Canada and around the world. 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 and innovative design simplification, GEH projects the BWRX-300 will require significantly less capital cost per MW when compared to other SMR designs. By leveraging the existing ESBWR design certification, utilizing the licensed and proven GNF2 fuel design, and incorporating proven components and supply chain expertise, GEH believes the BWRX-300 can become the lowest-risk, most cost-competitive and quickest to market SMR. This MOU is non-exclusive and non-binding.
