U238 > Pu239 Fast Spectrum Molten Salt Reactor

Post by matthewwight » Mar 15, 2019 10:06 am

Why can't we do Uranium 238 > Plutonium 239 in the fast spectrum using Molten Salt?

What are the disadvantages to doing this over LFTR?

This would require chloride salts. There is experience with molten chloride salts, for example, in manufacturing aluminum. As far as I know, no one has ever built a chloride reactor. Mastering the chemistry of high radiation, actinides and fission products will be challenging.

Fast spectrum reactors can also use fluoride salts. The following link includes some information on possible salts for fast spectrum fluoride reactors.
page 24 of 46 or the pdf or page 8 of the report.

Hope it helps.
