国外快堆退役中废钠处理经验及启示

Experience and Enlightenment of Waste Sodium Treatment in SFR Decom missioning

钠冷快堆因其安全性能好,成为第四代反应堆中研发进展最快、距离商业化核电厂建设目标最近的第四代堆型。依据国外部分钠冷快堆的退役经验,总结了钠冷快堆退役时的放射性分布特点,介绍了退役产生的大量废钠及工艺系统中残留废钠处理的工程经验和启示,结合国内快堆发展情况提出了在设计和运行阶段便于钠冷快堆退役的设想。

Because of its excellent safety performance, the sodium-cold fast reactors(SFR) is the fastest development and the closest to the target of commercial nuclear power plant construction of fourth generation reactor. This paper introduces the experience of some SFR’s decommissioning abroad, summarizes the distribution characteristics of radioactivity in SFR’s decommissioning, introduces the treatment experience and enlightenmeng of primary and secondary sodium and residual sodium in SFR’s decommissioning, and puts forwards the idea of facilitating the decommissioning of SFR in the design and operation stage combining with the development of SFR at home.
