BWXT to build nuclear steam generators for Rolls-Royce 470 MW reactors

Rolls-Royce SMR, a UK-based company developing a 470-megawatt small modular pressurized water reactor (SMR), has entered into a contract and memorandum of understanding (MoU) with Canadian nuclear engineering firm BWX Technologies Inc. (BWXT) to design and supply nuclear steam generators for its reactor fleet. Each Rolls-Royce SMR unit will use three steam generators, which BWXT’s Ontario-based subsidiary will produce, leveraging its 60 years of experience and over 315 units shipped globally. The MoU also includes plans for localization of manufacturing to support global deployment of Rolls-Royce SMRs. The Rolls-Royce SMR is designed to generate 470 MWe (1358 MWth), providing low-carbon energy sufficient to power one million homes for 60 years, with safety features including multiple layers of redundancy and environmental protections. The reactor uses a three-loop pressurized water system where heat from the nuclear core transfers to water under high pressure
