s weapons-grade fissile material still being produced today?
Yes. India and Pakistan openly produce such material for weapons, as does North Korea. Russia continues to produce 1.2 tons of weapons-grade plutonium each year, because the reactors that produce it provide essential heat and power for nearby communities. Israel refuses oversight of its nuclear activities, and is probably still producing plutonium. Iran is actively working to produce it. The U.S. stopped producing fissile material for nuclear weapons in 1992. In addition, facilities in several countries separate tens of tons of weapons-usable plutonium from civilian reactor fuel every year, and this plutonium is piling up in storage — to the point that it will soon exceed all the world’s stockpiles of weapons plutonium combined.
