The first task of a nuclear weapon design is to rapidly assemble a supercritical mass of fissile (weapon grade) uranium or plutonium. A supercritical mass is one in which the percentage of fission-produced neutrons captured by other neighboring fissile nuclei is large enough that each fission event, on average, causes more than one follow-on fission event. Neutrons released by the first fi… WebNuclear can be built.weapons proliferation There are two types of nuclear weapons: Fission bombs (“atomic bombs”) harness the energy released in fission reactions; the Hiroshima and Nagasaki bombs were fission weapons.
