Interfacing the output of severe accident analysis with the input of radiological consequence analysis is an important and mandatory procedure at the beginning of Level 3 PSA. Such interfacing between the severe accident analysis code MELCOR and MACCS, one of the most commonly used consequence analysis codes, is relatively tractable since they share the same chemical groups, and the related interfacing software, MelMACCS, has already been developed. However, the linking between MAAP, another frequently used code for severe accident analyses, and MACCS has difficulties because MAAP employs a different chemical grouping method than MACCS historically did. More specifically, MAAP groups by chemical compound, while MACCS groups by chemical element. An appropriate interfacing method between MAAP and MACCS has therefore long been requested by users. This study suggests a way of extracting relevant information from MAAP results and providing proper source term information to MACCS by an appropriate treatment. Various parameters are covered in terms of magnitude and manner of release in this study, and special treatment is made for a bypass scenario. It is expected that the suggested approach will provide an important contribution as a guide to interface MAAP and MACCS when performing radiological consequence analyses.

在 3 级 PSA 开始时，将严重事故分析的输出与放射性后果分析的输入连接起来是一个重要且强制性的程序。严重事故分析代码 MELCOR 与最常用的后果分析代码之一 MACCS 之间的这种接口，由于它们具有相同的化学基团，因此相对易于处理，并且已经开发了相关的接口软件 MelMACCS。然而，MAAP（另一个经常用于严重事故分析的代码）与 MACCS 之间的联系存在困难，因为 MAAP 采用了与 MACCS 历史上不同的化学分组方法。更具体地说，MAAP 按化合物分组，而 MACCS 按化学元素分组。因此，用户长期以来一直要求 MAAP 和 MACCS 之间的适当接口方法。本研究提出了一种从 MAAP 结果中提取相关信息并通过适当处理向 MACCS 提供适当源术语信息的方法。本研究涵盖了各种参数的大小和释放方式，并针对旁路情况进行了特殊处理。预计在进行放射后果分析时，建议的方法将作为 MAAP 和 MACCS 接口的指南提供重要贡献。
