摘　　要：乏燃料后处理过程产生的放射性废气中含有多种属性差异较大的放射性核素,其处理方法各有特点。本文介绍了乏燃料后处理厂放射性废气中^(85)Kr、~3H、^(129)I、^(14)C的国外先进处理方法,重点论述了碘和氪的处理方法,分析了需要关注的化学安全问题,并讨论了相应的预防措施、探测手段和纠正措施,为商用后处理厂废气处理系统的设计和事故分析提供了参考和建议。Radioactive gas wastes are generated during reprocessing spent nuclear fuel. The treatment approach is different due to different radionuclides. In the paper the several advanced foreign treatment approaches of the main radionuclides of the radionuclides gas waste are described, including 85Kr, 3 H, 129 I, and 14 C. The treatment approach of 85 Kr and 129I are discussed in detail and main chemical safety problems are analyzed. Preventive measures, detection means, corrective measures are also discussed. The reference is offered to the design and accident analysis of nuclear fuel reprocessing plant.
