President of the United Nations conference to negotiate a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination released the text of a Draft Convention on the Prohibition of Nuclear Weapons (courtesy of ReachingCriticalWill.org). The conference, established by the UN General Assembly in 2016, held its fist session in March 2017. It will resume its work on June 15, 2017.
Some provisions of the draft address the issue of fissile material production. The annex on safeguards requires parties to submit to safeguards all their source or special fissionable material. It also requires that the equivalent of INFCIRC/153 comprehensive safeguards are applied on all source or special fissionable material in all peaceful nuclear activities within the territory of a State, under its jurisdiction, or carried out under its control anywhere.
