A limited investigation of neutron absorption was conducted to examine the relative effectiveness of crucfform and cylindrical control rods. If such data could be firmly established, reactors using cruciform rods could be readily analyzed by transforming the rods to their cylindrical equivalent then applying traditional theories. Conversely, the number of rods required in a reactor and their lceation could be determined for cylindrical rods then transformed to equivalent cruciform rods. In the present context, only the cruciform rods are of engineering interest; the eylindrical rods are namely an analytical device. The Monte Carlo method was selected for this study to minimize the number of approximations required. The asane with which it can handle complex geometries makes this method particularly attractive for the control rod problems, but it often becomes very expensive to follow a sufficient number of neutrons to achieve satisfactory statistics. The project was, in part, an experiment to determine if this tyce of problem could be solved with reasomable accuracy at a reasonable cost with Monte Carlo. (auth)
