French public multinational industrial conglomerate Arvea has used CHARLI robot for extraction of sodium from EDF's nuclear installation in France.

The robot was used for EDF's laser cutting operations in the reactor vessel of the Superphenix fast neutron reactor, which is currently being dismantled at Creys-Malville in France.

CHARLI is a concatenation of two French abbreviations: “CHAR” referring to the remote operated vehicle used for the cutting and “LIposo” referring to the interconnection piping between the primary pumps and the base frame that supported the fuel assemblies.
