摘要
介绍了非饱和浸出实验条件下水泥固化体试块周围水的饱和度 f对137 Cs浸出影响的一些结果,包括累积浸出份额Ft、浸出通量分数Jn和等效扩散系数De。结果表明:Ft随f的增大而增大;Jn随着浸出时间的增加明显降低,随f的增加略有增加;De随f的增加而增大。
Some leaching results about effect of saturation around the solid cementitious waste form on leaching of 137Cs under unsaturated condition are introduced in the paper, including cumulative leaching fraction, Ft, leaching flux fraction, Jn, and effective diffusion coefficient, De. The results show that F, increases with saturation, f; Jn decreases obviously with time, and increases slightly with f; as well as De increases with f.
