Method for preparing high radioactive waste curing treatment base material

Abstract

The invention relates to a method for preparing high radioactivity waste solidification treating base material which comprises the following steps: preparing the material: using nature hyacinth, CaCO3 and TiO2 as raw material and extracting them by weight ration: nature hyacinth: CaCO3:TiO2 =26-32:29-35:35-42; correct grinding: loading each raw material into the correct grinding device, adding the grinding ball to do correct grinding 30-60 minutes; burning: burning at the temperature 1150 deg. to 1350 deg. 20-60 minutes to obtain the product.

Description

technical field

[0001] The invention relates to the treatment of radioactive waste, in particular to a method for preparing a base material for solidification treatment of high-level radioactive waste. The method prepares perovskite zircon (CaZrTi 2 o 7 ), titanite (CaTiSiO 5 )-based minerals, especially suitable for solidification of high-level radioactive waste. Background technique

[0002] The radioactive waste produced by various nuclear reactors, nuclear power plants and other devices is quite harmful and cannot be discharged directly to the environment. It must be solidified by a suitable method and stored in isolation by an appropriate device until the radioactive elements in it decay to no effect on the environment. up to the hazard. The solidification treatment and disposal technology of low-level radioactive waste is relatively mature and has been widely used. The solidification treatment and disposal technology of high-level radioactive waste is still in the ...
