| 摘 要： | 以去离子水为释放环境，研究核电厂废树脂和浓缩液水泥固化体被完全浸泡情景下核素90Sr、137Cs、60Co的浸出行为。分析中以有效扩散系数表征浸出行为。试验结果表明：固化体中的核素累积浸出份额不超过4%，137Cs浸出最快，90Sr其次，60Co最慢；同类废物体的抗压强度越大，核素浸出速率越慢。

| Abstract: | The release behavior of radioactive nuclides 90Sr,137Cs and 60Co in NPP resin and concentrate cement-solidified waste form was studied.The release surrounding is that the waste is totally immersed by deionized water.The effective diffusivity was taken as release behavior.The results show that cumulative leaching fraction of nuclides in test solidified waste is under 4%,the release of 137Cs is the fastest,90Sr is the second and 60Co is the slowest.Nuclides releasing in the same waste sample becomes going down with compressive strength enlarging. |

| Keywords: | solidified waste form radioactive nuclide release diffusivity |
