FMCT

The Fissile Material Cutoff Treaty (FMCT) is a proposed international treaty to prohibit the further production of fissile material for nuclear weapons or other explosive devices. The treaty has not been negotiated and its terms remain to be defined. According to a proposal by the United States, fissile material includes high-enriched uranium and plutonium. According to a proposal by Russia, fissile material would be limited to weapons-grade uranium and plutonium. Neither proposal would prohibit the production of fissile material for non-weapons purposes, including use in civil or naval nuclear reactors.
