Utilization of atmospheric dispersion simulations for nuclear emergency countermeasures

Hamuza, E.-A.; Nagai, Haruyasu  ; Sagara, Hiroshi*

WSPEEDI atmospheric dispersion simulations related to radionuclide discharge from nuclear power stations can be used for the consideration of crisis management. WSPEEDI can output crucial information regarding environmental distributions of radionuclides and weather patterns for nuclear emergency counter measures. This study will make use of such information to assist in the planning of crisis management for local governments. Data of atmospheric dispersion simulations from a nuclear power plant will be assembled according to WSPEEDI's output. The output will be assembled in such a way that will show experts the most important of information during a crisis, one example would be of air dose rate in a residential area. This will essentially help experts determine the best course of action in regards to evacuation in case a nuclear emergency does occur.
