Distribution of fissionable material in thermal reactors of spherical geometry for uniform power generation

McCready, Robert R., Spooner, Robert B., Valerino, Michael F.

The two-group equations for reflected thermal reactors of spherical geometry are solved for constant power generation over the reactor-core volume. Illustrative calculations are made for specified core and reflector compositions and a range of reflector thicknesses to obtain the distributions of fissionable material over the reactor volume required to give uniform power generation. The calculations show that for reactors with moderate or thick reflectors substantial increase in reactor power output can be achieved.
