“Westinghouse is pursuing a disciplined APX technology strategy built on the proven AP1000 reactor and extended through the AP300 SMR,” said Dan Sumner, President and Chief Executive Officer of Westinghouse. “We continue to make investments to strengthen our proven APX platform, and our ongoing collaboration with Amentum is expected to accelerate the licensing of the AP300 SMR with the NRC. Separately, our two companies will work together to enhance our engineering and execution capabilities for delivering 1-gigawatt reactors at scale.”
“Amentum’s expertise spans the full spectrum of the nuclear project lifecycle, accelerating the development and deployment of advanced nuclear solutions, strengthening energy security and powering the growth of AI and other energy critical industries,” said John Heller, Amentum Chief Executive Officer. “There is an expanding global market for firm baseload power, and our collaboration with Westinghouse will enable us to help meet that demand.”
The Westinghouse APX strategy offers a single technology platform enabling the fleet delivery of the AP1000 reactor and the AP300 SMR. The APX platform is based on the proven innovations and technology of the AP1000 plant, including validated engineering, components, licensing strategies, fuel design and supply chain. The APX strategy offers the grid-scale, commercially available AP1000 reactor for near-term global fleet deployments, while developing the AP300 SMR to address additional market segments with smaller energy requirements. Amentum’s engineering capacity and nuclear experience will strengthen the industrial base and delivery model, enabling the repeatable deployment of the APX technology suite.
Under the most recent agreement, Westinghouse and Amentum will collaborate to obtain regulatory approval for the AP300 SMR by the U.S. Nuclear Regulatory Commission, a major milestone in bringing the technology to market.
Westinghouse and Amentum have an established history of partnership on nuclear projects worldwide, including nuclear power and decommissioning projects in the United States, United Kingdom, Poland, Slovakia, Lithuania and South Africa.
