Geopolymer curing method for fluorine-containing radioactive waste liquid
The invention relates to a geopolymer curing method for fluorine-containing radioactive waste liquid, which belongs to the field of radioactive liquid waste curing treatment, and comprises the following steps: (1) mixing aluminosilicate mineral or aluminosilicate industrial waste with volcanic ash activity, an alkali activator and fluorine-containing radioactive waste liquid, uniformly mixed aluminosilicate inorganic polymer slurry is obtained; (2) transferring the aluminosilicate inorganic polymer slurry with certain flowability into a forming mold or an appliance to be compacted, and discharging internal bubbles; and (3) curing the aluminosilicate inorganic polymer slurry under a certain condition to form a geopolymer cured body. By adopting the method disclosed by the invention, the fluorine-containing radioactive waste liquid generated in the molten salt reactor operation and spent fuel post-treatment process can be stably and efficiently solidified and treated.
本发明涉及一种含氟放射性废液的地质聚合物固化方法，属于放射性液体废弃物固化处理领域，包括以下步骤：(1)将具有火山灰活性的硅铝酸盐矿物或硅铝酸盐工业废物、碱激发剂和含氟放射性废液混合，得到混合均匀的硅铝酸盐无机聚合物浆料；(2)将具有一定流动性的硅铝酸盐无机聚合物浆料转移至成型模具或器具中振实，排出内部气泡；(3)将硅铝酸盐无机聚合物浆料在一定条件下养护成地质聚合物固化体。采用本发明所述的方法，可以稳定、高效地固化处理熔盐堆运行和乏燃料后处理过程中产生的含氟放射性废液。
