I'd say it's imaginary if they don't exist. Your claim that, "They’re currently being deployed in industrial settings around the US." isn't really accurate, is it?

Edit: some context I was able to find:

"The US has approved a single design for a small, modular nuclear reactor developed by the company NuScale Power. The government's Idaho National Lab was working to help construct the first NuScale installation, the Carbon Free Power Project. Under the plan, the national lab would maintain a few of the first reactors at the site, and a number of nearby utilities would purchase power from the remaining ones.

With the price of renewables dropping precipitously, however, the project's economics have worsened. Some of the initial backers started pulling out of the project earlier in the decade, although the numbers continued to fluctuate in the ensuing years.

The final straw came on Wednesday, when NuScale and the primary utility partner, Utah Associated Municipal Power Systems, announced that the Carbon Free Power Project did not have enough utility partners at a planned checkpoint and, given that uncertainty, would be shut down. In a statement, the pair accepted that "it appears unlikely that the project will have enough subscription to continue toward deployment.""
