What has the NWS done so far (prior to the current Review Cycle)?

France definitively ended its nuclear testing in 1996 and dismantled in an irreversible manner its nuclear testing facilities in French Polynesia.

France built simulation capacities which are it presents as a sustainable substitute to nuclear testing to ensure the safety and reliability of its nuclear arsenal, without resorting to nuclear testing.

What is the NWS doing on this action in the current Review Cycle?

France has continued to refrain from nuclear-weapon testing and to use and develop its simulation programme.
