摘要: 为了提高水泥固化方法对含硼废树脂的包容率,通过改变固化配方,在大亚湾核电厂(GNPS)和岭澳核电厂(LNPS)的放射性废物处理系统进行了现场固化试验研究。结果表明,使用改进后的工艺进行水泥固化,废树脂的包容率从32.4%提高到46.3%,相对于原工艺包容率增加幅度42.9%,固化体体积减少了30%。该方法生产的固化体性能满足GB 14569.1—2011的各项要求。经过6年的工程实践,证明改进后工艺可在不改变核电厂固化系统原设施的情况下使用。

Abstract: In order to improve the resin cement solidified waste for boron tolerance rate, by changing the curing formulations, field solidification studies were carried out at the radioactive waste disposal systems of Daya Bay Nuclear Power Plant (GNPS) and Ling Ao Nuclear Power Plant (LNPS). Results show that the spent resin inclusive rate increased from 32.4% to 46.3%, improved 42.9%, solidified volume decreased by 30%. Performance of the solidified waste satisfies the requirements of GB 14569.1—2011. Six years of engineering practices have proved that the improved cement solidification process can be used in nuclear power plants curing system without changing the original facility situation.

Key words: PWR nuclear power plant, boric acid solution, radioactive spent ion exchange resin, a new technology of cement solidification
