X-energy gets green light to build its first small modular nuclear reactors

By · Via TechCrunch · Published by Everything Blog

In short

The project targets commercial operations in the early 2030s, with each helium-cooled unit producing 80 megawatts of electricity and 200 megawatts of heat. Major tech firms like Amazon are backing the technology to address surging power demands from data centers, with Amazon leading a $500 million funding round. Despite this milestone, the advanced reactor sector faces skepticism, leaving X-energy’s shares trading at less than half their initial public offering value.

Nuclear startup X-energy announced Monday that it had been given the go-ahead from federal officials to build its first four commercial reactors.

The Nuclear Regulatory Commission (NRC) approved the construction permit application for four of X-energy’s Xe-100 reactors at a Dow chemical plant in Texas. Each reactor will be capable of generating 80 megawatts of electricity and 200 megawatts of heat. X-energy says the approval is the first for an advanced nuclear reactor at an industrial site in the United States.

The U.S. nuclear industry has pinned its hopes on small modular reactors — or SMRs — like those being developed by X-energy. By shrinking the reactor, proponents say it will speed construction and reduce costs, though those advantages have yet to be proven. No SMR is currently in operation in the U.S., and X-energy says Dow’s reactors won’t be operational until the early 2030s.

X-energy claims that its reactor design, which flows helium gas over uranium-containing fuel pellets, is safer than many existing reactors, but the Union of Concerned Scientists questioned the claim and the speed with which X-energy…
