May be, but it's just a small version of the classic design.
So, it potentially could have the classic problems. I'm more impressed with a revolutionary design, e.g. Terrestrial Energy. Molten salt is both coolant and fuel. But, it's Canadian! :) Alex "There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge." -- Isaac Asimov |

I like the safety design of the cooling issues, lose power motor quits holding up

Like (at least one design for) the brakes on an elevator
It's held up by the middle of a leaf spring. If the cable snaps, the leaf spring flattens out pushing the ends against the rails. -- Drew |

That simple Idea made Otis rich. I had an Idea once; why ain't I rich?
(I thought it would be cool to use quite more of The Sun™); no solar panels, Jeez! ..but at least there were water-or-other heat exchangers: a friend used to schlep items to Pacific Isles --for the natives' kick-start -- screw petroleum imports. Next one: save/later sell Water before it's competing with Gold/Aurum (or the Rare Earth elements). |

Excuse me?
You need a cooling pool and a generator. That thing does not exist on its own and the only thing it puts out is steam in a closed loop. |

The rods will fall automatically if power is lost.
And there are other safeguards built around the coolant in the reactor itself. Regards, -scott Welcome to Rivendell, Mr. Anderson. |

Decent pr page
https://www.nuscalepower.com/technology/technology-overview I was doing some reading a few days ago and it showed it at a large scale plant which included it needed to be immersed in a pool of coolant. Can't find that now. |

I saw that, or one like it
The point was that site selection, design and prep becomes lots easier, then you truck in the pre-built reactors (plural) and set them up in the pool. Some existing generator sites could be converted, reusing the existing distribution infrastructure. -- Drew |
