摘要
分析了碱渣中放射性核素构成,并对特定组成体系进行了比活度理论计算,论述了影响碱渣极低放化的因素,对碱渣如何实现极低放化提出了建议,并推导出了尾渣达到极低放水平时的铀含量上限。
The composition of radionuclides in uriniferous alkalescence dreg is analyzed, the theoretical calculation of radioactive activity concentration in a specific component system is carried out, the factors affecting the radioactive activity of uriniferous alkalescence dreg are discussed, some suggestions are put forward to achieve very low-level waste, and the upper limit of uranium content is deduced.
