摘要/Abstract

摘要： 从配方水泥改进和提高废物包容量的角度出发,参照《低、中水平放射性废物固化体性能要求——水泥固化体》(GB 14569.1—2011)的要求,从实验室规模冷试、200 L和400 L规模冷试三个阶段,开展了核电厂含硼浓缩液的固化配方改进和水泥品牌替代研究,研究过程中水泥固化工艺模拟核电现场固化工艺。结果表明:配方改进后,替代品牌水泥固化体样品的抗冲击性、抗压强度、抗冻融性、耐γ辐照性和抗浸泡性均满足国标要求,与原配方及原品牌水泥相当;固化废物体积包容量从46.99%提升至57.63%,固化每吨废物的材料成本降低了69.29%。本研究结果可用于核电厂真实废物的水泥固化验证和处理。

Abstract: A study on formula improvement for cement solidification of boron-containing concentrates and cement replacement was carried out. Based on the requirements of GB 14569.1—2011 “Performance requirements for low and intermediate level radioactive waste form-Cement solidification form”, cold tests were conducted with scales from laboratory, 200 L to 400 L, respectively, and the on-site solidifying process in nuclear power plants is simulated. Experimental results showed that the impact resistance, compressive strength, free liquid, freeze-thaw resistance, γ-irradiation resistance and immersion resistance of cement solidified samples meet the requirements of national standards, and the waste containment rate is increased from 46.99% to 57.63%. The cost per ton of solidifying waste materials is reduced by 69.29%. The recommended formula can be used to solidify real radioactive wastes.

Key words: boron containing concentrate, cement solidification waste, containment capacity
