用于放射性废物处理的HIC容器设计优化

Optimization of HIC Container Design for Radioactive Waste Treatment

核能作为清洁、高效的能源,是不可再生能源的重要替代品之一,也是我国优化能源结构、合理进行能源保护、开发与利用的有效选择,同时放射性核废物的处理也成了核电发展的一个重要环节。相比于传统的水泥固化技术,高完整性容器(HIC)能够直接盛放干燥后的放射性废树脂和浓缩液干燥盐,具有更高的废物最小化水平,成为放射性废物管理的主要的发展方向之一。本文针对目前混凝土高完整性容器体积较大、防上浮效果不佳以及内容物包覆性差的缺点,进行设计优化,开发出具有更高性能的混凝土高完整性容器并进行了一定的工程应用验证,为核电厂和化工厂产生的放射性废物的高效处理提供了技术支持。

As a clean and efficient energy,nuclear energy is one of the important substitutes for non-renewable energy,and it is also an effective choice for optimizing energy structure,rational energy protection,development and utilization of our country.At the same time,the treatment of radioactive nuclear waste has become an important part in the development of nuclear power.Compared with traditional cement curing technology,high integrity container(HIC)can directly hold the dried radioactive waste resin and concentrated liquid drying salt(has a higher waste minimization level),which has become one of the main development directions of radioactive waste management..In view of the shortcomings of the current high integrity concrete container,such as the large volume of the container,poor anti-floating effect and poor covering property of the contents,this paper carried out design optimization,developed a concrete high integrity container with higher performance and conducted certain engineering application verification,providing technical support for the efficient treatment of radioactive waste generated by nuclear power plants and chemical plants.
