Context and challenges
The rehabilitation and dismantling of old installations is a regulatory requirement in the perspective of sustainable development.
These operations currently concern the old UNGG "Natural Uranium Graphite Gas" type reactors on a nuclear site and in particular the G2 and G3 reactors (40MW power - commissioned from 1959/60 and shut down in 1980 and 84). Before launching the phase related to the dismantling of the naves, this client wanted to demolish the control buildings.
This client called on Assystem for a project management assistance mission in the context of the demolition of UNGG nuclear reactor control buildings.
