摘要

研究反应堆的安全分析需要对停堆后沉积在实验和反应堆结构中的热量进行估算。对反应堆几何结构中沉积能量的准确评估可以更好地确定散热要求，并确保有效冷却。然而，根据具体情况进行实验安全分析往往费时费力。本文介绍了一种基于创建通用材料辐照数据库的方法，以加快这一过程。辐照数据库是通过计算单个化学元素实验中的延迟加热而创建的。然后，创建的数据库可以快速计算任意材料成分实验的延迟加热。本文展示了两个应用程序，以演示延迟加热计算工作流程并验证通用材料辐照数据库方法。这些应用包括一个简单的演示练习和一个高级试验反应堆实验。结果表明，通用材料辐照数据库方法与各种实验的参考值之间总体上具有良好的一致性。

Generic material irradiation database for delayed heating calculations

Safety analyses in research reactors require the estimation of heat deposited in experiments and reactor structures after shutdown. The accurate assessment of the deposited energy across a reactor geometry better determines the heat removal requirements and ensures effective cooling. However, the development of experiment safety analyses on a case-by-case basis often proves to be effort and time-consuming. This article introduces a method based on the creation of a generic material irradiation database to expedite the process. The irradiation database is created by calculating the delayed heating in experiments of individual chemical elements. Then, the created database enables the quick calculation of the delayed heating of experiments of arbitrary material composition. This article showcases two applications to demonstrate the delayed heating calculation workflow and verify the generic material irradiation database method. These applications include a simple demonstration exercise and an Advanced Test Reactor experiment. The results display an overall good agreement between the generic material irradiation database method and reference values for a wide variety of experiments.

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.
