Abstract

The proliferation resistance (PR) of several small modular reactors (SMR) is investigated in terms of material characteristic and other extrinsic parameters with COMPRE methodology developed by KINAC. In this work, plutonium (Pu) production amount and isotopic yield are newly introduced as key metrics in material characteristic. Their functionalization is performed with a linear regression method based on sparse core depletion data. Nevertheless, a clear discrepancy is observed in Pu buildup and its quality depending on SMR type and core burnup status. Some of the non-light water SMRs exhibit a higher proliferation concern and their PR score trends are clearly different compared to conventional pressurized water reactors (PWR). Other extrinsic parameters are evaluated based on development status of representative SMRs. At present, liquid metal cooled-fast reactor (LMFR) and molten salt reactor (MSR) receive low scores due to their limited technical maturity in reactor design and related I&C equipment. We conclude that distinct safeguards approaches, suitable for a wide range of SMR designs should be developed for commercial use in the near future.

在钚生产的辅助下，利用 COMPRE 方法评估 SMR 的抗增殖能力

利用 KINAC 开发的 COMPRE 方法，从材料特性和其他外在参数的角度研究了几种小型模块化反应堆（SMR）的抗增殖性（PR）。在这项工作中，新引入了钚（Pu）生产量和同位素产量作为材料特性的关键指标。它们的功能化是通过基于稀疏岩芯损耗数据的线性回归方法实现的。然而，根据 SMR 类型和堆芯燃烧状态的不同，钚的积累及其质量也存在明显差异。一些非轻水 SMR 表现出更高的扩散关注度，其 PR 分数趋势与传统压水堆（PWR）明显不同。其他外在参数则根据具有代表性的 SMR 的发展状况进行评估。目前，液态金属冷却快堆（LMFR）和熔盐堆（MSR）的得分较低，因为它们在反应堆设计和相关 I&C 设备方面的技术成熟度有限。我们的结论是，应在不久的将来开发出适用于各种 SMR 设计的独特保障方法，以供商业使用。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
