Low level radwaste disposal problems are complex. Many important issue, such as radionuclide migration in the geosphere, must be carefully evaluated before making decision. This project will explore the use of a hydrogeological decision support system for solving these complex problems. The system will integrate hydrogeological analysis tools, geographic information system, mathematical models, stochastic and statistic methods, graphical interface, and decision system. By using the system, it is expected that many different alternatives can be efficiently analyzed and evaluated, and results can be presented much more effective to decision makers, while compared with the conventional presentation. Basing on the prototype system developed in the last two years, this project will integrate more analysis tools and improve the functions of the system.

中文摘要低放射性废料处置所牵涉之问题甚为广泛且复杂，其中又以放射性核种於地下水中迁移所造成之风险性分析最为重要，一般而言，一个水文地质决策支援系统将结合水文地质、地理资讯系统、数学模式、序数及统计、图形介面、优化及决策分析等理论及工具，方能使该系统迅速分析各种不同方案，并以最有效方式将分析结果呈现於决策者；因此，本计画预计延续八十二年至八十三年间，初步完成之整合风险分析模式之决策分析系统刍形，并於其基础上继续整合及发展一些关键技术及工具，以增加系统必备之功能，使其系统更趋完善，达到实用之目的。
