Eastern Idaho nuclear reactor project downsized
A project to build a first-of-its-kind nuclear reactor in eastern Idaho has been significantly downsized.
The initial plan for the Carbon-Free Power Project was to build 12 interconnected miniature nuclear reactor modules to produce a total of 600 megawatts. It would be the first small modular reactor in the United States. After the company tasked with manufacturing the plants said it could make the reactors more power-efficient, planners reduced the project down to six module reactors that could produce 462 MW total.
“After a lot of due diligence and discussions with members, it was decided a 6-module plant producing 462 MW would be just the right size for (Utah Associated Municipal Power Systems) members and outside utilities that want to join,” said LaVarr Webb, UAMPS spokesman.
The project between UAMPS and Portland-based reactor producer NuScale received $1.4 billion from the U.S. Department of Energy last year. The reactor is planned to be built on the DOE’s 890-square mile desert site west of Idaho Falls at Idaho National Laboratory. The plant is expected to be running by 2029.
“A 6-module plant allows us to get to full subscription faster, but we would have reached full subscription regardless,” Webb said of the project’s ability to achieve full financial commitment from partners. “Before joining a next-generation, first-of-a-kind nuclear plant, utilities obviously want to be certain the plant is feasible and will be built. Now that we have made significant progress, including a large cost-share award from the Department of Energy, and NuScale has received design approval from the (Nuclear Regulatory Commission), we’re seeing more and more utilities express interest in the plant.”
