Re-processing method for spent nuclear fuel

Creators

Description

Purpose: To re-process spent oxide or mixed oxide fuels at a reduced cost while decreasing the amount of secondary radioactive wastes generated. Method: Oxide fuels, etc. to be re-processed are once converted into chlorides so that simple electrolytic refining method can be applied. Then, deposition products are again converted into oxides and regenerated as fuels. This method can simplify the re-processing step as compared with the conventional Purex process and can reduce the cost. In addition, conversion into chlorides can eliminate the requirement of using organic solvents which are degraded remarkably with radioactive rays as in the Purex process and can conduct re-processing while reducing the amount of the secondary radioactive wastes generated.
