【摘要】 本文对在我国高放废液分离流程中产生的中低放非α废液的大体积浇注水泥固化，在实验室小试条件下进行了可行性研究。结果表明，经浓缩、脱硝及中和处理后，非低α中放废液可用大体积浇注水泥固化进行处理和处置。推荐的固化配方为：水灰比１．０～１．１，盐灰比０．１８～０．２０，及占水泥重量０．５％（ｗｔ）的水泥高效缓凝减水剂。固化体第４２ｄＣｓ的浸出率为１０－３～１０－５ｃｍ／ｄ，Ｓｒ的浸出率在３．１×１０－３～６．５×１０－３ｃｍ／ｄ之间，改进抗浸出性能尚待进一步研究。更多还原

【Abstract】 Immobilization feasibility for non α low and intermediate level liquid waste fractions generated from Chinese high level radioactive liquid waste total separation process was studied. After concentration, denitration and neutralization, the non α ILLW generated from separation process can be immobilized by means of large volume pour of cement solidification. The introductive solidification parameter was water to ash ratio 1.0～1.1,salt to ash ratio 0.18～0.20 and retarding reduce hydrate addition was 0.5 %(wt) of cement. The leach rate of Cs is 10 -3 ～10 -5 cm/d and Sr is (3.1～6.5)×10 -3 cm/d in the solids at the 42 d. Improving of the leachability is further studing. (更多还原
