摘要
在放射性废固处理处置问题愈发突出的情况下,聚乙烯高整体性容器(HIC桶)在ALARA (合理可行尽可能低)、废物最小化、可操作性、系统复杂性及成本等各方面具有优势,HIC桶在美国等核技术发达国家广泛使用,具备良好的工程应用业绩,拥有被不断验证和改进的成熟配套设备,同样,在我国从山东海阳核电站开始,HIC桶将会陆续应用在放射性废物处理和处置上,这不可避免的会涉及HIC桶的贮存问题,根据GB14500-2002和GB14589-93的规定,低、中放固体废物的贮存期一般不宜超过5年。本文结合国内的标准规范和海阳核电厂的工程应用,阐述了HIC废物桶在核电厂产生后的贮存要求和暂存库的设计考虑。
Under a more challengeable situation of radwaste treatment and disposal, high integrated con-tainer (HIC drum) has advantages in respect of ALARA, waste minimization, operability, system complexity and cost. In countries with nuclear technology highly developed, such as USA, HIC is widely used and has abundant project references, the complete equipment of which is continuously verified and improved. Likewise in China, since firstly used in Shandong Haiyang nuclear power station, HIC will be subsequently applied in other radwaste treatment and disposal projects, which inevitably brings about the problem of HIC storage. In accordance with the specifications of GB14500-2002and GB14589-93, storage period of low and intermediate radioactive solid waste shall not be more than 5 years. By combining standards and regulations in China as well as project application of Haiyang nuclear power station, this article states the storage requirements of HIC waste drum generated in nuclear power plant and design considerations of interim store.
