After an attempt to use this element instead of tungsten in lamp filaments was unsuccessful, the Westinghouse Lamp Plant in New Jersey supplied this element to the government during World War Two. An isotope of this element decays into barium, krypton, and three neutrons. This element's depleted form is used in dense weapons, while its enriched form is used by nuclear power plants. Name this element just before neptunium
