There is certainly a lot of talk about micro reactors. I have yet to see anything materialize in the US. The MARVEL test reactor is meant for something puny like 100kw. Nuclear is something that benefits from scale -larger installations are just going to have better economics per watt.

No it really does not look that way. It sort of sounds like it might look that way at some point in the future but micro reactors are not useful for utility generation today.
