The collapse of NuScale’s project should spell the end for small modular nuclear reactors
Although there were problems specific to the Utah Associated Municipal Power Systems project, the financial challenges and cost trends witnessed in that case will afflict any SMR project.

This past November, the Utah Associated Municipal Power Systems, or UAMPS, terminated what was to be “the first NuScale Power small modular reactor plant to begin operation in the United States.” This was a death foretold; the red flags have been obvious for years now. Although there were problems specific to that project, the financial challenges and cost trends witnessed in this case will afflict any small modular nuclear reactor project. In a rational world, no utility or government would invest another dime on these theoretical reactor concepts.

As announced in 2015, the UAMPS project initially involved constructing 12 reactor modules capable of generating 600 MW, with the aim of starting operations “around 2023,” and at an “overnight cost” of $3 billion. In 2018, NuScale announced a design modification with each module now producing 60 MW of electricity, or 720 MW for the whole plant, claiming this would lower the cost “on a per kilowatt basis from an expected $5,000 to approximately $4,200.

The estimated costs of the project rose to $4.2 billion in 2018, then $6.1 billion in 2020, and finally $9.3 billion in 2023, after it was scaled down to 462 MW in 2021. In the end, the costs were clearly too high for UAMPS members to bear.
