URANIUM DENSITY OF SYSTEMS INVOLVING MUTUALLY INSOLUBLE MATERIALS

摘要

Critical masses, as they apply to the establishment of safe geometries, are altered by the involvement of hydrogen as a moderator. Theoretically, uranium compounds and hydrogen compounds which exhibit mutual insolub¬ility should make proportional contributions to the composite uranium density of any system wherein they are combined. The uranium densities of four such systems were determined experimentally and the results obtained support the validity of the theory. Certain fundamental considerations are examined which are potential sources of error in the application of these physical principles.
