Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.
Westinghouse Electric Company is the world's leading supplier of new nuclear plants, products and technologies. We provide our utility customers around the world with the most reliable, dependable nuclear power plants, nuclear fuel, plant automation and operating plant products and services. Our AP1000© reactor is the only operating Generation III+ reactor with fully passive safety systems, modular construction design and has the smallest footprint per MWe on the market. Our AP300™ SMR, which launched this year, is single-loop pressurized water reactor that is based on the proven, licensed AP1000 technology. In addition to these advanced LWRs, Westinghouse is also developing non-traditional nuclear technologies in order to meet the needs of diverse and evolving global markets. Specifically, the Westinghouse eVinci™ microreactor is designed to provide approximately 5 megawatts of electricity / 15 megawatts of thermal power 24 hours a day, 7 days a week for eight-plus years without refueling. The Westinghouse Lead-cooled Fast Reactor is a utility-scale (450 MWe) Generation IV plant designed to best complement advanced passive LWRs through enhanced application versatility that combines flexible cost-competitive electricity, high-temperature heat and the capability to support a closed fuel cycle. Our comprehensive and innovative technology portfolio creates a blueprint for a carbon-free ecosystem that serves communities large and small with reliable, cost-effective electricity, district and process heat, and water desalination.
