Nuclear study for a small-sized BeO-moderated naturul uranium, CO/sub 2/- cooled power reactor was made. The core parameters, including the bucklings with and without allowances for poisoning and temperature effects, were calculated for several sets of solid rod radii and the channel and cell sizes. Fixing the core size about 3 m high and 3.6 m in diameter, with 90 cm thick graphite reflector and the rod and channel radii at 1.35 cm and 4.0 cm respectively, so as to conform with 2.54 cm thick steel pressure vessel of diameter about 6 m and the heat transfer calculations, it is found that the thermal power output, which is about 33 Mw for the uniform core, can be increased by about 20% on breaking the core into two zones, while the fuel inventory is decreased by about 9%. The extra reactivity required for poison and temperature effects is found to be about 4%. (auth)
