Patent application -- technique for reprocessing SNF published August 7, 2014
(proposed as an alternative / improvement vs Purex or other prior art pyroprocessing techniques)

Patent assignee -- COMMISSARIAT A I'energie atomique et aux ene alt

Abstract:

"The invention relates to a process for manufacturing an oxychloride or oxide of actinide(s) and/or of lanthanide(s) from a chloride of actinide(s) and/or of lanthanide(s) present in a medium comprising at least one molten salt of chloride type comprising a step of bringing said chloride of actinide(s) and/or lanthanide(s) present in said medium comprising at least one molten salt of chloride type into contact with a wet inert gas."

Chloride volatility or fractional crystallization would be a more compact methods to partition used nuclear fuel. The products could be of use with MSR. The critical need is to get a concentration of plutonium and trans-uranium elements which can act as the fissile feed for a part of the uranium recovered or for thorium.
