Investing money in nuclear instead of solar/wind is literally a gift to the fossil fuel industry. Solar/wind are cheaper per MWh output (4x cheaper unsubsidized than NuScales pre-construction claimed price estimate) and faster to construct, so for the same amount invested you phase out far more fossil fuels.

Plus you can't even use nuclear plants as economically viable dispatchable power: cost per MWh directly scales upwards as capacity factor drops, because basically all the costs are fixed not variable depending on how often you run it. So if at 90% capacity factor it's $120/MWh (as the Utah NuScale is, pre-sunsidy), at 60% capacity factor it's $180/MWh. Compare to wind and solar at around $30-40/MWh and it's just a bad look.

There's a reason the initial pumped-hydro energy storage plants were built in the US to allow dispatchability of nuclear power... And now that same kind of storage idea can more cheaply be applied to solar/wind. ie, nuclear doesn't actually solve the storage issue in the way that proponents like to claim, so it doesn't even have that going for it.

And nuclear plants have never shown a positive learning curve, where repeated builds decreased costs over time.

It's not even small amounts we are talking about investing, that could be seen as OK for initial demonstrator plants. The Utah project cost estimate is now over $9 billion.

The nuclear industry needs to be allowed to die due to its lack of economic competitiveness.

It's safe, and low-carbon, but a bad use of money/time/workforce/effort.

"US pushes forward with wasting money on over-expensive small nuclear reactors, rather than cheaper renewables"

Not uplifting.

For just the subsidy amount here, not including any of the private investment, you could produce more solar or wind power than the NuScale reactor will produce. Adjusted for capacity factor.

It's a bad investment.

Ahem,...(Me looking northwest and east of Maine)....

You know, there are literally two Canadian provinces (Quebec and New Brunswick) a relatively short drive away filled with millions of French speakers. Not like it's that rare of a thing, just saying.
