Nixon canceled the Mars program where the vast majority of cutting edge nuclear research was happening - tech like the nuclear lightbulb (search my comments for details) that could have matured and saved us by now. He was no friend to nuclear, just the entrenched nuclear industry.
- pfdietz 4y agoThis is magical thinking. No, nuclear light bulbs would have made absolutely no sense for use on Earth.
- akiselev 4y agoYes, they would have. Still do. In fact, they built several experimental setups and were just short of testing fissile material before the program was canceled. If anyone would like a starting point for research instead of lobotomized rhetoric like "this is magical thinking", request this paper: https://ntrs.nasa.gov/citations/19750027209 https://ntrs.nasa.gov/citations/19750027209
- pfdietz 4y agoYes, let's vaporize nuclear fuel. What could possibly go wrong with this stunning large brain engineering. It is surely no more burdensome on materials than solid fuel sealed away in metal tubes. /s
- akiselev 4y agoYes that's how civilization was built. By pushing material science further and further. Do you think pressurized steam turbines just magically appeared? Read the papers, they explain it all and characterize the tests.
- pfdietz 4y agoCivilization advances by trying huge numbers of things, most of which are horrible and bad. The rare winning technologies survive. Implying that nuclear lightbulbs for terrestrial generation would have been in this elite group of winning technologies is just ludicrous.
- akiselev 4y agoVaporizing nuclear fuel is how we enrich it. Uranium => Uranium Hexaflouride sublimed at 57C => Gaseous centrifuge to separate the isotope. We've been doing it since the Manhattan Project, since before nuclear power plants were even a thing. https://en.wikipedia.org/wiki/Enriched_uranium#Centrifuge_techniques https://en.wikipedia.org/wiki/Enriched_uranium#Centrifuge_te...
- pfdietz 4y agoComparing uranium hexafluoride vapor at 57 C to incandescent vaporized uranium + fission products at 22,000 C. The materials problems with the latter are just a bit more severe!
