SMR nuclear gets approval but costs are still going up

Modular reactor pioneer NuScale finally got one of its designs certified by the Nuclear Regulatory Commission, but the company is still years away from a deployment.

NuScale’s unprecedented design approval is a good reason for stakeholder celebration — but the company isn’t out of the woods just yet. It’s already had to revise its projected project costs and hit a regulatory snag.

NuScale has an agreement to build a first-of-its-kind 462-megawatt project in Idaho with Utah Associated Municipal Power Systems (UAMPS), a group of 50 municipal utilities across seven Western states. Higher materials costs, interest rates and inflation have already forced NuScale to raise its projected cost from $58 per megawatt-hour to $89 per megawatt-hour; UAMPS’ project management committee approved the cost increase earlier this month.


Has the fuel issue been resolved? Russia turned out to be the only supplier. And US replacement a few years away.
