Abstract

In this study, we developed a Decommissioning Waste Assessment Module (DWAM) for Heavy Water Reactors (HWRs). To evaluate the waste amount of radioactive structures that make up a significant portion of decommissioning waste, we establish a comprehensive DB containing detailed information on the volume, weight, material type, and radioactivity of each decommissioning waste segment. Decommissioning waste assessment algorithms were developed and applied in the proposed module to optimize the calculated results, and their performance was evaluated to ensure accuracy and reliability. The DWAM currently being developed for the Wolsong Unit 1 commercial pressurized heavy water reactor is a technology that has the potential to be utilized not only for domestic reactors but also for reactors worldwide. In addition, the technology is expected to contribute to the development of technology related to the decommissioning of both radioactive and non-radioactive structures.

开发重水反应堆退役废物评估模块

在本研究中，我们开发了重水反应堆退役废物评估模块（DWAM）。为了评估占退役废物重要部分的放射性结构的废物量，我们建立了一个综合数据库，其中包含每个退役废物部分的体积、重量、材料类型和放射性的详细信息。我们开发了退役废物评估算法，并将其应用于拟议模块中，以优化计算结果，并对其性能进行了评估，以确保准确性和可靠性。目前正在为卧龙一号机组商用压水重水反应堆开发的 DWAM 是一项不仅有可能用于国内反应堆，而且有可能用于全球反应堆的技术。此外，预计该技术将有助于开发与放射性和非放射性结构退役有关的技术。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
