Quoted from mbwalker:Small Modular Reactors (SMR) are interesting approach instead of the gigantic 1000 MW sites. Built to a standard on a production line. A lot smaller in size, in the 60 MW range. U.S. Nuclear Regulatory Commission (NRC) approved a design a couple of years ago, but can't say I've followed it much.
I do want the hot tub reactor.
