X-energy submits Xe-100 reactor for UK design assessment

X-energy on June 2 submitted its Xe-100 high-temperature gas-cooled reactor to enter the UK's Generic Design Assessment, the Office for Nuclear Regulation-led licensing pathway that evaluates a reactor's safety, security, and environmental case independent of a specific site. The submission, made with utility partner Centrica, supports plans to deploy up to 6 GW of new nuclear in Britain, with Hartlepool identified as the preferred first site for a 12-unit installation, and the assessment is expected to conclude by the end of 2029. The 80-MWe TRISO-fueled design is also advancing toward its first U.S. deployment with Dow in Texas.
