Where I’m working we are developing a liquid sodium cooled reactor to process “spent” nuclear fuel.
It Pours when it Rains.
The Alvin Weinberg Foundation is a London-based charity advocating for Gen IV reactors and thorium fuel, lists seven current international MSR projects: Ian Scott’s Moltex project in the UK, Elsa Merle-Lecotte’s EVOL project in France, the US Transatomic Power project, David LeBlanc’s Terrestrial Energy project in Canada, Kirk Sorensen’s Flibe Energy project in the USA, Motoyasu Kinoshita’s Fuji Reactor project in Japan, and Hongjie Xu’s MSR Project in China.

In addition to these another US based outfit called Thorcon by Martingale has thrown their hat in the ring. Beyond their first announcement a month or so ago, there’s little information on them. However, their staff is pretty impressive. It includes a guy who helped Edward Teller write his last paper on thorium reactors back in 2004 and a guy who has been in charge of a number of big projects for Google.http://nucleargreen.blogspot.com/2015/01/thorcon-moving-forward.html

My understanding is that the msr reactors can burn both spent uranium and thorium. Some more. Some less depending on the design.
Wouldn’t a salt solution be water soluble? The fuel mixture might solidify upon leakage, but what if it leaks into standing water? I see a potential for ground water contamination here. Was this addressed in the talks?
....and what happened to those Italian guys that had a mystery bottle of water with special electrodes that produced electricity and heat....?
For later.
This is not table salt.
Most research has focused on FLiBe, because lithium and beryllium are reasonably effective moderators, and form a eutectic salt mixture with a lower melting point than each of the constituent salts. Beryllium also performs neutron doubling, improving the neutron economy.
FLiBe is a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF2). It is both a nuclear reactor coolant and solvent for fertile or fissile material. It served both purposes in the Molten-Salt Reactor.
FLiBe salt has low hygroscopy and solubility in water.
The main goal of a prism-style or FBR is disposition of plutonium and other transuranics, but in principle they can be used to recycle and consume all actinides.
Not a much different concept than the old FFTF at Hanford, WA.

...after it melts everything below it between here and China.....
The fuel salt must be within a special moderator confinement to reach criticality, otherwise no reaction is supported. A leak of reactor salt-diluent fuel with short-term reaction side products will still rapidly cool ( below 459 °C for FLiBe )and form solid.
No “metallic core meltdown” implied in the movie effects of “The China Syndrome” nor Chernobyl’s “positive void coefficient” design flaw allowing a runaway reaction.
As long as the rain isn’t self-boiling.....
Would changing the pH have any effect on its solubility in water?
You would change PH of the mixture by adding other components. But you haven’t changed the chemical composition of the salts so the would not be affected.
