NuScale's SMR is ~77MW - which is a medium sized data center.

AFAIK, that's typical consumption for data centers being built today.

A site that contained a single NuScale reactor would have unacceptable fixed costs per MW. The UAMPS/NuScale CFPP was planned to have six reactors to amortize those fixed costs (like personnel) over more output.

Note also that the cost figures NuScale gave for that was the cost after 40-50 reactors had been built (and with federal subsidy), not FOAK costs.

If you can build N reactors, the datacenters will suddenly appear nearby if they're allowed to. Power is the current bottleneck in the US
