Title:
放射性廃棄物リサイクル施設
Document Type and Number:
Japanese Patent JP6781774
Kind Code:
B2
Abstract:
The alleged invention is related to nuclear power generation technologies and can be used for recycling of low and medium radioactivity waste, in particular, nuclear waste from VVER and RBMK reactors and other nuclear installations.The objective of the alleged invention is to extend the functionality, enhance wear-resistance and efficiency of the recycling plant. The technical result of the invention is to design a flexible operation mode in which nuclear waste with different radioactivity level would be recycled in automatic or automated mode, and to ensure increased wear-resistance of the plant components.This technical result is achieved in the radioactive waste recycling plant which consist of the following components: 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; the recycling plant (in accordance with the invention) is additionally equipped with, 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. The control module is electrically connected with the electric hardware of a waste feed unit, a plasma shaft-type furnace, a receiving tank for molten slug and with the electric hardware of the air supply unit which delivers the air to the furnace and to the combustion chamber, and the slug discharge control is electrically connected with the electric hardware of the slug discharge unit.Utilization of the alleged invention allows to provide a flexible operational mode for the radioactive waste recycling plant.
