Long learning process during 40 years of operation of surface

repositories

Surface repositories accomodate most of the waste being produced in

France, including medical waste.A solution for all operating waste from NPP.

A solution for most of dismantling waste.

Experience gained in closure and long term monitoring of disposal

sites.

Allows to accept very large pieces (vesselhead, steam generators, etc)
