Nuclear power plant radioactive organic waste splitting and mineralizing treatment reactor

Abstract

The invention provides a nuclear power plant radioactive organic waste splitting and mineralizing treatment reactor, which comprises a reaction section and an expansion section, wherein a high-temperature water vapor inlet, a nitrogen inlet and an oxygen inlet are formed in the lower part of the reaction section; a resin slurry inlet, a catalyst inlet, a waste oil or waste organic solvent inlet, an anticoagulant inlet, a mineralizing agent inlet and an active carbon inlet are formed in the middle part of the reaction section; the expansion section is located above the reaction section; and thetop of the expansion section is provided with an organic dry waste or waste filter core inlet and a solid and gas outlet. Furthermore, the invention further provides a method for treating nuclear power plant radioactive organic wastes by adopting the nuclear power plant radioactive organic waste splitting and mineralizing treatment reactor.

Description

technical field [0001] The invention belongs to the technical field of nuclear power. More specifically, the invention relates to a pyrolysis and mineralization treatment reactor for radioactive organic waste in a nuclear power plant, which is applicable to the treatment of medium and low-level radioactive organic waste. Background technique [0002] Nuclear power units, research reactors, and some nuclear facilities will produce various types of radioactive waste during normal operation, including: ion exchange resins, activated carbon, filter cores, sludge, waste oil, waste organic solvents, and labor protection products produced by daily maintenance, Wipe down stain remover etc. Most of these wastes are organic wastes, and the conventional treatment methods will have the problems of relatively large capacity increase and high disposal waste. Especially waste resin, although its volume and quantity account for a small share in the whole radioactive waste, the radionuclide...

AI Technical Summary

Problems solved by technology

The cost of this method is low, but the volume of waste after treatment increases greatly, and there is a problem of high nuclide leaching rate in long-term disposal

In addition, radioactive sludge, waste oil, waste organic solvents and other radioactive wastes currently have no effective treatment methods, and can only be temporarily stored in nuclear power plants, pending the application of new technologies.
