Technical Report

OSTI ID:4331824
In order to help determine the radial thickness and permissible amounts of poisons for the graphite reflector of the plutonium production core of the UPR, a few twogroup two-region criticality calculations were made. A curve of reflector savings, in per cent of an infinite reflector, as a function of thickness for pure graphite reflectors is given. A curve of savings, in per cent of an infinite pure graphite reflector, as a function of amount of aluminum and water content is given. The results show that a two foot graphite reflector will yield a reflector savings of 85% of that obtainable with an infinite reflector. Five percent aluminum reduces the reflector savings of a pure graphite reflector by approximately 10% and 5% water results in a reduction of approximately 30% in the savings of a pure graphite reflector.
