Webster, J W; Schulze, O A

Results of criticality calculations are given for an intermediate energy BeO moderated reactor of 2.69-ft core diameter and for numerous variations of its parameters. The subjects quantitatively studied are: effect of core composition and core size, effect of xenon and uranium lumping effect of reflector, and effect of iteration of the source term. Graphs are given for normalized fissioning spectrum, spatial power distribution and leakage spectrum on each reactor assembly where significant. Also included is a graph showing the effect of reflector thickness on reactivity and a graph showing the convergence of the fission distribution with its iteration as the source distribution. The method of calculation is a 31-group numerical multigroup technique essentially that used by KAPL with modifications to adapt it to IBM computation. (auth)
