Westinghouse’s AP300 SMR positions itself as one of the world’s most revolutionary SMR solutions ready for deployment.
The company’s AP1000 reactor, a Generation III+ design with fully passive safety systems, is recognized for its efficiency and modular construction, boasting the smallest footprint per megawatt electric among similar technologies. Reed Clay, president of TNA, highlighted Westinghouse’s expertise, stating: “Westinghouse has unmatched nuclear expertise, providing the technology that is used to run nearly half of the world’s operating nuclear plants, including the four commercially operating reactors at South Texas Project and Comanche Peak here in Texas.” He added: “TNA is proud to partner with Westinghouse to ensure safe and reliable nuclear energy continues to power future generations here in Texas.”
Globally, six AP1000 reactors are operating at record levels of performance and availability, with 12 more under construction and six additional units contracted. Building on this technology, Westinghouse has developed the AP300 small modular reactor (SMR), which utilizes the proven engineering and supply chain of the AP1000 to reduce deployment risks. Unlike other SMRs that rely on untested technologies, the AP300 is designed for rapid and reliable implementation.
Westinghouse also offers the innovative eVinci microreactor, which operates with minimal moving parts, functioning similarly to a battery. Capable of delivering continuous electricity for over eight years without refueling, the eVinci provides scalable power solutions, ranging from a few kilowatts to 5 megawatts, suitable for various applications.
Dan Sumner, interim CEO of Westinghouse, emphasized the company’s commitment to Texas, stating: “TNA is providing bold leadership to bring the benefits of reliable, abundant and clean nuclear energy to Texans.” He further noted: “As a company that has been a part of the Texas nuclear ecosystem for decades, Westinghouse stands ready to help the state explore new opportunities – whether it is proven grid-scale technologies like our AP1000 reactor, our AP300 SMR or flexible next-generation innovations like our eVinci microreactor.”
In a separate development, Westinghouse and Ukraine’s Energoatom signed an agreement in July 2025 to strengthen energy security by establishing a new assembly line for VVER-1000 fuel elements at Energoatom’s subsidiary, AtomEnergoMash. This partnership underscores Westinghouse’s global role in advancing nuclear energy solutions.
The collaboration with TNA positions Westinghouse to support Texas in expanding its nuclear energy capabilities, ensuring a reliable and sustainable energy future.
