Westinghouse is advancing its eVinci microreactor development through criticality testing at Los Alamos National Laboratory, validating its design and supporting future licensing and deployment. The process reduces uncertainty by refining models and confirming performance of key components like HALEU TRISO fuel and heat pipe technology.

This Wire brief sits within Fusion42's coverage of Clean Energy.

◆ ◆ The Wire takeaway

You need to rethink timelines and costs in microreactor projects as criticality testing cuts development guesswork for Westinghouse's eVinci. This moves the market from concepts to viable products you can build on.
