Achievement is a Critical Step to Deploy the eVinci Microreactor

Westinghouse Electric Company has received approval for its eVinci^® Microreactor’s Preliminary Safety Design Report (PSDR) from the U.S. Department of Energy (DOE). With this key milestone, Westinghouse becomes the first microreactor developer to secure an approved PSDR for the National Reactor Innovation Center’s Demonstration of Microreactor Experiments (NRIC-DOME) test bed at the Idaho National Laboratory (INL).

The eVinci microreactor builds on decades of industry-leading Westinghouse innovation to bring carbon-free, safe and scalable energy wherever it is needed.

The PSDR provides the detailed design and safety case overview of the eVinci nuclear test reactor required by DOE to locate it at the NRIC-DOME. The eVinci test reactor is a scaled-down 3 MWt heat pipe microreactor designed to demonstrate key portions of the eVinci design and enable the development of the larger commercial eVinci microreactor.

“Becoming the first test reactor to receive approval of its PSDR demonstrates the maturity of our eVinci design and underscores the momentum we have in commercializing and deploying this technology,” said Jon Ball, eVinci Technologies President at Westinghouse. “We appreciate our strong partnership with the teams at INL and DOE and look forward to their continued collaboration in the NRIC-DOME program.”

The eVinci Licensing Department is now developing the draft Preliminary Documented Safety Analysis, which is the third of four DOE submissions needed to site the eVinci test reactor.

The eVinci microreactor builds on decades of industry-leading Westinghouse innovation to bring carbon-free, safe and scalable energy wherever it is needed for a variety of applications, including providing reliable electricity and heating for remote communities, universities, mining operations, industrial centers, data centers, and defense facilities, and soon the lunar surface and beyond. The resilient eVinci microreactor has very few moving parts, working essentially as a battery, providing the versatility for power systems ranging from several kilowatts to 5 megawatts of electricity, delivered 24 hours a day, 7 days a week for eight-plus years without refueling. It can also produce high temperature heat suitable for industrial applications, including alternative fuel production such as hydrogen, and has the flexibility to balance renewable output. The technology is factory-built and assembled before it is shipped in a container.

Westinghouse Electric Company is shaping the future of carbon-free energy by providing safe, innovative nuclear and other clean power technologies and services globally. Westinghouse supplied the world’s first commercial pressurized water reactor in 1957 and the company’s technology is the basis for nearly one-half of the world's operating nuclear plants. Over 135 years of innovation makes Westinghouse the preferred partner for advanced technologies covering the complete nuclear energy life cycle.
