This was researcher was completed by the United Aircraft Corporation in the late 60's and early 70's before it was canceled by Nixon along with the Mars program. It was under a NASA contract for space exploration so the literature is in the context of a rocket engine but it is even more compelling as a terrestrial reactor as it uses a tiny amount of fuel (tens of kilos instead of tens of tonnes) and actively keeps that fuel at supercritical so if power is lost the entire thing fizzles out. This is a fast neutron design with an extremely high neutron cross section, far beyond that of any other reactor, easily allowing you to feed nuclear waste into it and very efficiently transmute much of it into fuel or more manageable waste that is then separated out by centrifuges (which are already in the design to separate usable UF6 from the neon exhaust). UAC was set to win a contract to test the reactor with nuclear fuel when NASA pulled the plug so the anti-nuclear crowd isn't to blame for that line of development dying.
However, all of the technological breakthroughs in computation, material science, and nuclear engineering needed to make this happen at an industrial scale have all been discovered since the project was canceled. If it weren't for all the anti-nuclear hysteria, we might have actually had someone willing to take the risk to bring the nuclear lightbulb reactor to market. Sadly, almost all of the scientists and engineers that worked on this design have passed on so the institutional knowledge is gone and the design was classified for a while so no other nations picked up on it in time. You may be able to find the original papers on NASA/JPL's archives but AFAIK they were reclassified a few years ago.
I believe they have a project in the works. I just watch documentaries, I am not a nuclear physicist or anything. It sounds like it is safe and efficient. We've got a huge supply of thorium.
Every time we have a massive nuclear disaster the defense (a valid one!) Is that the disaster happened from a poorer technology that isn't used anymore today.
If we had built out nuclear earlier we would have had a lot more nuclear disasters.
The problem with nuclear is solely that by the time the technology became good enough that it could be used fairly safely it became way more expensive than almost all competitors including most other renewable sources.
And this is even before including the geopolitical limitations of nuclear. Would we be living in a better world if every country including countries like Afghanistan and Pakistan had easy access to nuclear.
As of May 2017, the People's Republic of China has 37 nuclear reactors operating with a capacity of 32.4 GW and 20 under construction with a capacity of 20.5 GW.[1]
Compare:
As of 2016, there are four new reactors under construction with a gross electrical capacity of 5,000 MW, while 33 reactors have been permanently shut down.
I'm lead to believe the reason China can have 5 times the number of new nuclear builds is because China seems to be able to get shit done while infrastructure in the US languishes. I could be wrong, I'm just going by what internet would have me believe.

Then we would have even more problems with final disposal than we already have, that's the topic none of the pro-nuclear people ever want to touch on because they fully realize it's quite an issue.
As is, it's already bad enough how plant operators socialize these long-term costs while keeping all the profits private, which is the only way these operations can turn a short-term profit. Case in point: http://www.dw.com/en/german-government-does-nuclear-waste-de...
It's even more infuriating to see that quote of Sigmar Gabrial boasting that "society alone doesn't have to bear the costs". How generous of them to pay a little bit into a fund for the disposal of their own waste, while the German taxpayer will end up picking the brunt of the bill when, as always, everything ends up going way over the estimated costs.
Just take a look at Fukushima: TEPCO has a book equity of $US20 billion, total cleanup costs are estimated at $US250 billion, who's paying for that? Right, the Japanese government aka the tax payer.
If we had invested more in Nuclear it would be less of an issue. We've invented much safer reactors, and more efficient ones that produce much less waste. Probably much more would have been developed if the investment was there.
Many make this claim, but I do not buy it.
Take Australia as an example: relies on coal for around 85% of electricity production [1], also has some of the most expensive electricity in the western world [2] at around 29c / USD Kilowatt hour (that is over 2x the US national average).

I live in Tasmania now, I think most of our electricity comes from hydro. Thirty hydropower stations operating in Tasmania[1], but we still pay ~26 cents a kilowatt-hour here.
Also, agreed. Australia is a mess. I grew up in Newcastle, living in Toronto Canada now and love looking at where our energy comes from: https://www.cns-snc.ca/media/ontarioelectricity/ontarioelect...
No coal, beautiful!
I'll admit that no new hydro is arguably a good thing for certain aspects of sustainability, but it could be argued that new hydro is better than new coal or gas. That's sort of a false dichotomy because there are other options:
An in-principle agreement has been reached to build a new 144MW wind farm in central Tasmania[2], the first new wind project in the state in almost a decade[3].
The Franklin Dam project was to be 180MW, with arguable much greater capacity factor than wind.
