核动力装置退役中的低污染金属废物处理

Disposal of Low-Polluting Metal Wastes in Decommissioning of Nuclear Power Plants

核动力装置退役拆解时将产生大量金属废物,对于其中存在放射性污染的部分的处理应遵循相应的分类与处理准则。在分析国际国内标准要求的基础上,提出了可行的分类与处理方案,重点在于如何对低污染金属废物进行有限制再利用。通过某核动力装置退役工程的实际应用,验证了其实现废物最小化、降低处置成本的作用。

Nuclear power plant decommissioning will produce large amounts of metal wastes, and the disposal of the parts with radioactive contamination should follow the appropriate classification and processing guidelines. Based on the analysis of international and domestic standards, this paper puts forward the feasible classification and treatment plan, focusing on the restricted use of low-polluting metal waste. The practical application in a nuclear power plant decommissioning project verified that it can minimize the wastes and reduce the cost of disposal.
