Westinghouse Electric Company announced today that it has received formal approval from the U.K. Department of Energy Security and Net Zero (DESNZ) to commence the Generic Design Assessment (GDA) for its AP300™ Small Modular Reactor (SMR). This marks the first step in a two-stage GDA process, which will involve collaboration with the Office for Nuclear Regulation, the Environment Agency, and where applicable, Natural Resources Wales. The AP300 SMR leverages the proven Gen III+ AP1000® technology, previously approved in the U.K., U.S., and China, as well as meeting European Utility Requirements (EUR) standards, significantly reducing delivery risks for customers across various industries.
Dan Lipman, Westinghouse Energy Systems President, expressed gratitude to DESNZ for the rapid approval and emphasized the importance of the U.K.’s familiarity with the AP300’s technology. The approval follows the AP300’s selection by Great British Nuclear and Community Nuclear Power, Ltd. (CNP) for projects in Northeast England, which will capitalize on Westinghouse’s long-standing nuclear manufacturing presence in the U.K.
The AP300 SMR is distinguished as the only SMR based on an operational, advanced Generation III+ reactor, the AP1000, which allows for streamlined licensing and reduced technical risks. This established technology base ensures the first operational unit is anticipated by the early 2030s, offering competitive economics and reliability. The AP300 SMR is also under consideration by potential customers in the U.K., Europe, and North America.
Westinghouse Electric Company, a global leader in nuclear and clean power technologies, continues its legacy of innovation, having supplied the world’s first commercial pressurized water reactor in 1957. With over 135 years of expertise, Westinghouse remains a key player in advancing carbon-free energy solutions worldwide.
