Radiation Shielding Applications

Heavy concrete is standard concrete in which conventional aggregate (typically gravel) is replaced with aggregate composed of a dense material such as DUO2. While manufacture of heavy concrete for a given application is expected to be more expensive than standard concrete, there are circumstances where the reduced volume of the heavy concrete is expected to yield compensating cost reduction or other advantages. The purpose of this task is to bring heavy concrete technology to the point where a demonstrated technical basis for deployment exists. In particular, there is a need to establish (a) the ability to manufacture and the long-term behavior of large heavy concrete shapes to provide confidence in the reliability and safety, and (b) the cost of such shapes.
