S>Effects of gamma and neutron radiation are calculated for a Plutonium Reclamation Facility. Shielding requirements to give a dose rate around the equipment of approximately 2 mrem/hour for each of three design alternates are given. With 1/2 inch of lead on the hermetically sealed equipment, the working area dose rates are lowered to below 1.0 mrem/hour. With the one inch of lead shielding presence of fission products in the plutonium stream becomes a controlling factor in the extent to which gamma dose rates can be reduced in the working area. The impracticality of performing glove box operation through an 8- inch hood wall as necessary with a 6-inch plexiglas neutron shield requires either acceptance of a 10 mrem/ hour minimum radiation dose rate through one inch of lead or a change of design to reduce neutron dose rates. Extrapolation of potential dose rates to the hands for plutonium indicates a possible exposure of 100 mr/hour or more in terms of equivalent body dose rates. Elimination of all glove box operations with the hermetic equipment approach suggests its eventual adoption on all plutonium processing facilities involving contact mainteance. (auth)
