Abstract This work presents an illustration of Nagra’s AMAC (Advanced Methodology for Activation Characterization) approach to the South Korean pressurized water reactor Kori-1 decommissioning. The results achieved are supported by the existing experience from the detailed AMAC applications to Swiss NPPs and are used not only for a demonstration of the applicability of AMAC to South Korean NPPs, but also for a first approximation of the activated waste volumes to be expected from Kori-1. A packaging concept based on the above activation characterization is also presented, using the AMAC algorithmic optimization software ALGOPACK leading to the minimum number of waste containers needed given the selected packaging constraints. Nagra’s AMAC enables effective planning before and during NPP decommissioning, including recommendations for cutting profiles for diverse reactor components and building structures. Finally, it is expected to lead to significant cost savings by reducing the number of expensive waste containers, by optimizing a potential melting strategy for metallic waste as well as by significantly limiting the number of radiological measurements. All information about Kori-1 used for the purpose of this study was collected from publicly available sources.

Nagra 的 AMAC 方法根据其在瑞士核电厂的详细应用中获得的经验对 Kori-1 核电厂退役进行说明

摘要 这项工作展示了 Nagra 的 AMAC（活化表征高级方法）方法对韩国压水反应堆 Kori-1 退役的方法。取得的结果得到了从详细 AMAC 应用到瑞士核电厂的现有经验的支持，不仅用于证明 AMAC 对韩国核电厂的适用性，而且还用于对预期的活化废物量的初步近似。科里-1。还提出了基于上述激活特性的包装概念，使用 AMAC 算法优化软件 ALGOPACK 导致在给定选定的包装约束条件下所需的废物容器数量最少。Nagra 的 AMAC 能够在核电厂退役之前和退役期间进行有效规划，包括对各种反应堆组件和建筑结构的切割轮廓的建议。最后，通过减少昂贵的废物容器的数量、优化金属废物的潜在熔化策略以及显着限制放射性测量的数量，预计将显着节省成本。用于本研究目的的有关 Kori-1 的所有信息均从公开来源收集。
