AI Technical Summary

Technical Problem

The prior art is difficult to effectively carry out engineering barrier treatment of cesium radioactive solid waste in complex natural near-surface environments to prevent radioactive elements from leaking into the surrounding environment.

Method used

A disposal unit is set up in a radioactive decommissioned mine, and an anti-seepage layer and an anti-diffusion layer are laid at the bottom in turn. The cesium-containing radioactive solid waste is placed on the anti-diffusion layer, and the mixed filler is filled, and a bentonite and clay mixture layer and fly ash layer are laid to design layers of anti-seepage and leakage-proof structures.

Benefits of technology

Effective disposal of cesium-containing radioactive solid waste is achieved, preventing radioactive substances from oozing out, and ensuring the safety of the disposal environment and the protection of the surrounding environment.

Abstract

The invention discloses a method for treating cesium-containing radioactive solid waste, which comprises the following steps: filling solid waste in a packaging barrel or directly placing the solid waste in a uranium mine, designing and laying an impermeable layer and an anti-diffusion layer, filling a filler, covering a mixture of bentonite and clay, fly ash and the like, thereby achieving the effects of layer-by-layer seepage prevention and leakage prevention. And the cesium-containing radioactive solid waste is well treated.
