7.1 Molten Thorium Salt Reactors
- Molten Thorium Salt Reactors [2016-08]
If you got to go with fission, molten, not solid, thorium seems attractive. Youtube video has been pulled.
- Does not have expensive fuel rods.
- So does not have expensive fuel reprocessing.
- The above reduce profit margins of nuclear fuel industry so makes it hugely undesirable to them.
- Much, much, lower nasty transuranic elements produce, though it has some.
- Lower proliferation issues.
- China is moving on this [2016-08]
If the U.S. does not make and export these to the world, China surly will.
- Known history from 1960s [2016-08]
- Thorium Fuelled Molten Salt Reactors - The Weinberg Foundation Report - 2013 [2016-08]
- Passive Temperature Regulation: no control rods needed, or even wanted.
- No "melt down" problems.... already liquid
- Any overheating simply melts a freeze plug that drains the salt into safe holding area well before serious trouble.
Low tech automatic. All without special power, equipment, or monitoring. Fukushima events impossible. Any leaks are vastly easier to recover from.
- Much lower temperature and pressures than popular reactors.
- Can be made much smaller than Light Water Reactors
- Downsides include some radioactive leftovers, no infrastructure in place, no recent experience though US interest is picking up again.
7.2 Focus Fusion (a.k.a., "Plasma Focus" Fusion, a.k.a., "Dense Plasma" Fusion)
- Skeptical: my initial charm with FF has faded due to chemical and nuclear hazards not addressed in promotional materials
