WebDepleted uranium provides relatively poor attenuation for neutrons. Also, activation and transmutation (plutonium production) by neutrons would make it an undesirable shield material for attenuation of neutrons. It can be cast, forged, extruded, and machined. In the machining process protection must be provided against fire and toxicity.
