Westinghouse Electric Company has successfully completed the front-end engineering and experiment design (FEEED) phase for its innovative eVinci™ microreactor, paving the way for potential testing at Idaho National Laboratory (INL) in 2026.
The eVinci microreactor is among three designs being readied for trials at the world’s first microreactor test bed.
The FEEED process is integral in supporting developers with design and planning for the fabrication, construction, and testing of fueled reactor experiments.
This milestone includes developing a detailed schedule, budget, design, and test plan, along with a preliminary safety report to ensure secure operations.
“Completing the FEEED process marks a critical step to bringing the Westinghouse eVinci Microreactor to commercial operation,” said Jon Ball, President of eVinci Technologies at Westinghouse.
“We are targeting deployment of multiple eVinci microreactors across the world by the end of the decade, and continuous collaboration with NRIC, INL, and the Department of Energy is crucial to our efforts.”
Westinghouse will continue refining the design and preparing long-lead procurement items for the possible installation at DOME.
Meanwhile, Radiant and Ultra Safe Nuclear Corporation are also expected to finalize the FEEED process by year’s end.
The eVinci microreactor stands out for its compact size and capability. Designed to operate on sites as small as two acres, it can produce 5 megawatts of electricity for at least eight years before needing refueling.
This makes it an excellent choice for powering remote communities, mining operations, and data centers.
Additionally, its TRISO fuel offers increased resistance to corrosion, oxidation, and high temperatures, enhancing safety and reliability.
The microreactor can function without water, making it suitable for arid regions. Upon fuel depletion, the reactor can be simply removed and replaced, further simplifying its operational model.
With shutdown rods added for transit security and deep geological repositories planned for long-term fuel storage, the eVinci microreactor prioritizes safety in every aspect.
In 2023, Westinghouse announced plans to install the first eVinci microreactor in Saskatchewan, Canada, with the Saskatchewan Research Council approving a CAD 80 million project to build this pioneering facility. The microreactor is projected to be operational by 2029, supporting the broader goal of cutting 55,000 tons of CO2 emissions annually through this and future deployments.
DOME, the renovation project at INL, is designed to facilitate these experiments and help reduce the risks associated with developing new reactor technologies. Operated by NRIC, DOME will play a critical role in accelerating the development and commercialization of advanced nuclear technologies.
As the date for testing approaches, Westinghouse and its partners remain committed to delivering clean and innovative energy solutions, heralding a significant leap forward in the field of nuclear energy.
