模拟放射性树脂特种水泥固化提高包容量的研究

Study on Efficient Cementation of Simulated Radioactive Resins Using ASC Cement

摘要: 研究了用ASC特种水泥固化放射性废树脂过程中增加树脂包容量对固化体强度、核素浸出率和水化热温升的影响。研究结果表明:增加树脂包容量将使固化体强度有所降低,但当树脂包容量不大于60%的时候仍然可以满足废物处理和处置的要求;增加树脂包容量对核素浸出率影响很小,并且可使固化过程中的水化热温升有所降低。

Abstract: The strength, leaching rate of Cs~(+) ions and temperature rise were measured for ASC cementation matrix loading of resins. The results show that the strength of matrix is decreased when the loading of resins is increased, but the strength can meet the demands for disposal while the loading of resins does not excess 60%. Loading of resins does not affect leaching rates of ions in matrix. The temperaturerise resulted by hydration of cement will decrease when the loading of resins is increased.
