Galen, so what your suggesting is that we build a nuclear power plant based on OLD technology, and bad planning.
I, on the other hand believe that a lot has been learned and is being learned every day about safer use of nuclear based products.
Alan's thorium salt concept was well on it's way to being introduced in the US, if not for the particular moronic POTUS of the day, (and they say Mr T's bad) who decided to stop funding and research into thorium and divert the money or funding to nuclear weapons instead.
The full story is on Google from memory.

Imagine I'm a terrorist, wanting some U233 to make a bomb? I'm going to need kilograms of it!

And we have come to our senses, have built a dozen or so in our arid outback?

Monsour terroriste, has decided he can get past security and collect some from a molten salt reactor where the U233 is also liquid and operating in the safe zone between 700-1200C. Ouch, ouch that's F-ing hot he screams as he tries to extract a couple of spoonfuls, drop the lot on his foot (well, it's a liquid) then dances the highland fling at just below light speed as he reacts to his left foot evaporating, going up in smoke!

Defeated, he hops to it and makes a roo like escape hopping around on his remaining good foot, gets half a mile from the facility and drops dead from the ultra massive gamma radiation dose he received from exposure to unshielded U233!

Ok decides Monsour Teroriste mark two. I'll use a robot, heh, heh.
Robbie trundles in announcing danger, danger, Will Robinson, alien attack etc. And is beheaded by a laser beam as he tries to get past the metal detector and the massive ceiling-mounted electromagnet, placed there for just such an eventuality!

Moral, don't lose your head over a few grams of red hot liquid! Some things are too hot to handle, and nuclear material can be thermally and radioactively hot and just not safe outside the reactor and environs, safety features!

Yes, if we build a few thorium burning MSR's not too many geniuses are going to try and steal something they need to precipitate from solution and then challenge the Gamma radiation they could be exposed to! I don't see why they'd bother!

I mean it would be vastly easier and less challenging to build a fusion bomb! First, they'd have to get here, then beat the arid outback and our security, then get away unharmed! I mean given the turbines could be powered with hot, or super chilled, or both, air! That's where I'd build them.

Pardon the levity.

Alan, you are still dreaming.
