摘要： Recycling of low and medium radioactivity nuclear waste from VVER and RBMK reactors and other nuclear installations.
The invention uses a recycling plant consisting of a waste feed unit; a plasma shaft-type furnace with a melter in the hearth of the furnace and a slug discharge unit connected with a receiving tank for molten slug; an air supply unit delivering air to the furnace to a pyrolysis gas combustion chamber; an evaporative heat exchanger for sharp reduction of the flue gases temperature; a gas purification unit with a sock-type filter; a heat-exchanger and a scrubber; pumps and tanks for agents and recycled products; fittings; and at least, one control module which is electrically connected to the slug discharge control module, an interior environment control module, an equipment status control module and, at least, one gas analytical module.
