"This is where I did a spit take."

That's understandable. 470 MW is not "small." It's over 50% of the size of conventional PWRs. Also 470 MW is probably not sufficient for "one million homes." It might be sufficient for one million small efficiency apartments, assuming they are well built, equipped with modern appliances and not over occupied. But a conventional detached residential structure is 1 KW+. That's without charging any electric vehicles.

Marketing exaggerations aside, good to see at least some innovation in nuclear design. The design anticipates factory built reactor vessels, which is a fundamental improvement.
