Abstract
At the time of nuclear emergency, it is important to identify the type and the cause of the accident. Besides with these, it is also important to provide adequate information for the emergency response organization to support decision making by predicting and evaluating the development of the event and the influence of the release of radioactivity for the environment. Recently, a new type of nuclear disaster prevention support system called MEASURES (Multiple Radiological Emergency Assistance System for Urgent Response) was developed which provides not only the current state of the nuclear power plant and the influence of the radioactivity for the environment, but also the future prediction of the accident development. In order to provide the accurate results of these analyses quickly, MEASURES utilizes the various techniques, such as multiple nesting method, which narrows down the calculation area gradually, and parallel processing computer for three-dimensional analyses, such as air current distribution analysis. In this paper, the outline and the feature of MEASURES are presented, especially focused on the usage of parallel processing computer for the threedimensional air current distribution analysis with Regional Atmospheric Modeling System (RAMS) developed by Colorado State University.
