It is well known: it is a "political" deal between two party: the PS, that ruled between 2012 and 2017, and IIRC EELV, a "green" political party, one of the kind that do not like nuclear. The "green" party even wanted to completely dismantle the mox industry, but the PS eventually told them niet. Then it has not been reversed by the current ruling party.
