The RPV, which contains the reactor core and associated internals, is the largest component within the BWRX-300.
BWXT said work associated with the contract includes engineering analysis, design support, manufacturing and procurement preparations.
In October, GEH announced it had entered into a teaming agreement with BWXT Canada to cooperate on engineering and procurement to support the design, manufacturing and commercialisation of the BWRX-300 SMR.
Earlier this month, GEH announced that the BWRX-300 had achieved a significant pre-licensing milestone in Canada with the completion of phases one and two of the Canadian Nuclear Safety Commission’s (CNSC) vendor design review process.
GEH’s BWRX-300 is a 300 MW water-cooled, natural circulation SMR with passive safety.
Recently, GEH, OPG, SNC-Lavalin and Aecon signed a project delivery agreement for the partners to provide expertise and services to develop, engineer and construct a BWRX-300 SMR, with construction to be complete by late 2028.
GEH said there is growing, global interest in the BWRX-300.
Last month, Fermi Energia announced that it had selected the BWRX-300 for potential deployment in Estonia. Tennessee Valley Authority has begun planning and preliminary licensing for potential deployment of a BWRX-300 at the Clinch River Site near Oak Ridge, Tennessee. SaskPower has chosen the BWRX-300 for potential deployment in Saskatchewan in the mid-2030s.
In Poland, Orlen Synthos Green Energy and its partners have started the pre-licensing process by submitting an application to Poland’s National Atomic Energy Agency for assessment of the BWRX-300. Orlen plans to deploy a fleet of BWRX-300s with the potential for deployment of the first of those units by the end of this decade.
The CNSC and the US Nuclear Regulatory Commission are collaborating on reviews of SMRs such as the BWRX-300 and last month the CNSC and Poland’s National Atomic Energy Agency agreed to cooperate in the review of SMR technologies including the BWRX-300.
