Westinghouse eVinci™ Design Reaches Key US Licensing Milestone

Approval of Principal Design Criteria Simplifies Licensing for Customers

CRANBERRY TOWNSHIP, Pa.--(BUSINESS WIRE)--Westinghouse Electric Company announced today that the U.S. Nuclear Regulatory Commission (NRC) approved the Principal Design Criteria (PDC) Topical Report for the eVinci™ microreactor design.

As an integral part of the licensing process, PDCs define a reactor’s design bases, or how each part of the reactor’s structures, systems, and components will function. PDCs ensure that the design conforms to design bases outlined in NRC regulations. The approval of these PDCs provides a clear path to licensing the eVinci microreactor for deployment as well as simplifying and streamlining the licensing process for customers.

“Approval of our PDC topical report gives our customers confidence that the eVinci microreactor can be licensed for deployment in a highly streamlined and repeatable manner,” said Jon Ball, President of eVinci Technologies at Westinghouse. “This will allow customers to take advantage of the eVinci microreactor’s small size and transportability to rapidly deploy when and where they need them for cost-competitive and resilient power.”

This announcement is the latest in a series of licensing milestones for the eVinci microreactor, including the approval of the state-of-the-art eVinci Advanced Logic System^® Version 2 instrumentation and control platform.

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 data centers, the oil and gas industry, mining operations, remote communities, universities, industrial 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. 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.
