Mooneyham, A O

Criticality requirements for cylindrical, air-cooled, room temperature, homogeneous uranium carbide-graphite reactors utilizing completely enriched uranium and having graphite reflectors were determined. Results are presented in the form of graphs relating uranium weight, total reactor weight, reactor size, core composition, refiector thickness, and free flow ratio. The data are intended only for assisting in the selection of design points from a wide range of variables, and are not considered adequate for prediction of critical masses in actual critical assemblies. Some neutron flux spatial distributions are given. Also included are neutron flux energy distributions, fissioning energy distributions, and mean times between fissions for several reactors without reflectors. (auth)
