They are still going for big building size reactors that have site specific details even if the core is built in a "factory". This still doesn't scale well.

I wonder if it can be economical to go smaller still and ship a reactor and power generation (TRG maybe or a small turbine) that then doesn't require much other than connecting wiring and plumbing and its encased in at least one security layer covered in sensors if something goes wrong its all contained. Then its just a single lorry with a box you wire in. That has a chance of being scalable and easy to deploy and I can't help but think there is a market for ~0.5-10 KW reactors if they can get the lowest end down to about $20,000, it would compete OK with solar and wind price wise.

I suspect no one has bothered because the regulatory overhead means it has to be big enough to be worth it and like Wind power scales enormously with the size of the plant. But what I want is a tiny reactor in my basement, add a few batteries for dealing with the duck curve and you have something that will sit there producing power for 25 years and a contract for it be repaired and ultimately collected at end of life.

You can sort of do this today using the Tritium glow sticks and solar cells but it doesn't last long enough and the price is not competitive. Going more directly to the band gap in a silicon or something else semi-conductive and a long lived nuclear material could maybe get a little closer price wise.
