Popis: Technological aspects of 99Mo production from 235U at the VVR-ts nuclear reactor are considered. The nuclear target design with which the formation of liquid and solid wastes is reduced to a minimum and the forced system for cooling of nuclear targets in experimental channels of the nuclear reactor are reported. Schemes of 99Mo isolation from 235U fission products and of 235U regeneration after 99Mo isolation are described. The 99Mo and, correspondingly, 99m Tc produced from the regenerated 235U fully meet the technical specification and pharmacopoeial monograph for sodium pertechnetate.
