Abstract Most part of nuclear power sites around the world have multiple reactors, requiring different approaches to deal with plants interdependencies during its decommissioning. Usually, decommissioning strategies are proposed based on previous experiences. A strategy that would organize the decommissioning process is often proposed based on previous experience of similar projects. Different management tools for decommissioning cost estimation are found in literature but none of them focus on strategy proposal, which considers in a properly way plants interdependencies as well as mathematical models for costing the process. To overcome of these difficulties, the present work presents a method for decommissioning strategy proposal which could be used integrated with a mathematical model for cost estimation. Five strategies were obtained with the proposed method. The cost to decommissioning a case study site and its plants is also provided considering the Brazilian context.

考虑具有相互依存工厂的多反应堆场址的退役策略建议和成本估算方法

摘要 世界上大部分核电站都有多个反应堆，需要不同的方法来处理退役期间的工厂相互依存关系。通常，退役策略是根据以往经验提出的。组织退役过程的策略通常是根据类似项目的以往经验提出的。在文献中可以找到用于退役成本估算的不同管理工具，但它们都没有关注战略建议，战略建议以适当的方式考虑了工厂的相互依赖性以及计算过程成本的数学模型。为了克服这些困难，目前的工作提出了一种退役策略建议的方法，该方法可以与用于成本估算的数学模型结合使用。使用所提出的方法获得了五种策略。考虑到巴西的情况，还提供了使案例研究场地及其工厂退役的成本。
