On 25 March 2005 TENEX and French holding AREVA signed a €50 million contract on technology transfer.

An installation for depleted uranium defluorination is to be assembled at the Electrochemical Plant in Krasnoyarsk and launched into operation in 2009.

The contract envisages a transfer to the Russian party of the design documentation, shipment of technological equipment, follow on during assembly and testing, training of operation and service personnel.

AREVA possesses the world unique plant of such type. The facility located in Pierellate (Drome Department, France) has been since 1984 reprocessing depleted uranium hexafluoride from enrichment plants into highly stable uranium oxide U3O8. The Russian party showed interest mastering such technology on production scale that would help ensure safe storage of this valuable material along with production of hydrofluoric acid much in demand by chemical industry.
