The construction and operational data are presented for an experimental reactor using UF/sub 6/ as fissile material. The reactor was constnucted in order to study the chain reaction in gaseous UF/sub 6/, to correct the theoretical calculations, and to carry out research in reactor physics. The first experiments with UF/sub 6/ enriched up to 90% with U/sup 235/ were achieved in August 1957. Reactor characteristics are: diameter of the active core (beryllium), 116 cm; height of the active core, 108 cm; thickness of the side reflector (graphite), 50 cm; thickness of the upper and lower reflectors, 60 cm; the lattice spacing, 8 cm; the number of rectangular cross section channels, 148; the gas volume in the active core, 213 liters; the beryllium weight in the active core, 1370 kg; the aluminum weight in the active core, 62.8 kg; the critical mass (U/sup 235/2.024 kg; the critical mass (UF/sub 6/ with 90% coatent of U/sup 235/), 3.340 kg. Experiments show that by selecting favorable conditions it is possible to secure radiative stability of UF/sub 6/in a reactor. (R.V.J.)
