Fission Product: An atom produced through the splitting (fissioning) of a larger atom. Fuel Assembly: A number of nuclear fuel rods grouped together. Fuel Cladding: A long metal tube encasing the nuclear fuel rod. Cladding designed to prevent fission products which migrate from the nuclear fuel from escaping to the primary coolant system. Fuel Pellet: A cylindrical pellet of nuclear fuel typically consisting of uranium dioxide. Fuel Rod: A stack of cylindrical fuel pellets encased in fuel cladding.
