Abstract An integrated waste management approach for irradiated graphite was developed during the European Commission project ‘Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste’. This included the identification of potential options for the management of irradiated graphite, taking account of storage, retrieval, treatment and disposal methods. This paper describes how these options can be assessed using multi-criteria decision analysis (MCDA) for a case study relating to a generic power reactor. Criteria have been defined to account for safety, environmental, economic and socio-political factors, including radiological impact, resource usage, economic costs and risks. The impact of each option against each criterion has been assessed using data from the project and the wider literature. A linear additive approach has been used to convert the calculated impacts to scores. To account for the relative importance of the criteria, example weightings were allocated. This application has shown that MCDA approaches can be used to support complex decisions regarding irradiated graphite management, accounting for a wide range of criteria. Use of this approach by individual countries or organisations will need to account for the specific options, scores, weightings and constraints that apply, based on their national strategies, regulatory requirements and public acceptability.

开发用于评估辐照石墨综合废物管理方案的多标准决策分析框架

摘要 在欧盟委员会项目“辐照石墨和其他碳质废物的处理和处置”期间开发了辐照石墨废物综合管理方法。这包括确定辐照石墨管理的潜在选择，同时考虑到储存、检索、处理和处置方法。本文介绍了如何使用多标准决策分析 (MCDA) 对与通用动力堆相关的案例研究进行评估。已定义标准以说明安全、环境、经济和社会政治因素，包括放射性影响、资源使用、经济成本和风险。已经使用项目数据和更广泛的文献评估了每个选项对每个标准的影响。已使用线性加法方法将计算的影响转换为分数。为了说明标准的相对重要性，分配了示例权重。该应用表明，MCDA 方法可用于支持有关辐照石墨管理的复杂决策，考虑到广泛的标准。个别国家或组织使用这种方法需要根据其国家战略、监管要求和公众接受度考虑适用的具体选项、分数、权重和限制。该应用表明，MCDA 方法可用于支持有关辐照石墨管理的复杂决策，考虑到广泛的标准。个别国家或组织使用这种方法需要根据其国家战略、监管要求和公众接受度考虑适用的具体选项、分数、权重和限制。该应用表明，MCDA 方法可用于支持有关辐照石墨管理的复杂决策，考虑到广泛的标准。个别国家或组织使用这种方法需要根据其国家战略、监管要求和公众接受度考虑适用的具体选项、分数、权重和限制。
