RELATIONSHIP OF REFLECTOR THICKNESSES LESS THAN 30 CENTIMETERS TO CRITICAL MASS FOR THE 300 MEGAWATT P&WA FIREBALL REACTOR

Technical Report ·
OSTI ID:4795827
In order to decrease the over-all size and weight of the Fireball Reactor, a decrease in the size of the reflector was considered. The resulting change in critical mass was studied. A spherical mock-up of the PWAR was used for this study. Four cases involving four different reflector sizes were run on the IBM-701. A curve was plotted which showed that the per cent change in critical mass increased rapidly as the thickness of the reflector was decreased. (M.C.G.)
