Development of a computer code concerning the diffusion of radioactive effluents and radiological exposure following an accident

Technical Report:

Abstract

Cheap and clean energy can be supplied with nuclear power plant whose accident probability is very low comparing with that of the other industrial facilities. However, the consequences of severe accident of nuclear power plant may result in a critical impact on population and ecosystem over a wide area due to the radioactive effluents released into the atmosphere as was in the case of the Chernobyl accident. Therefore, it is necessary to prepare an effective computer analysis system for real-time dose assessment against a potential severe accident of nuclear facility. The objective of this study is a development of the real-time assessment system of environmental exposure dose in an emergency and the installation of its prototype system. Wind field model satisfying the mass conservation and Monte Carlo diffusion model to save computing time were developed in order to assess real-time diffusion of radioactive effluents in an accident. Comparing studies were done in 3 kinds of typical topographic situation dependent on every atmospheric stability. Data library of exposure doses was documented by several computer calculation so that computation time could be reduced considerably. These results of the computation with data library showed a good agreement with the real calculation by the  More>>

These results of the computation with data library showed a good agreement with the real calculation by the existing mode in which numerical integration model was used. And a graphic package was established that enabled to display the wind vector, concentration field of radioactives, and distribution of exposure dose every time step on the color graphic terminal. Work station was composed of host computer CDC-CYBER, graphic application processor - TEK 4301, graphic CRT - TEK 4125 and hard copier - TEK 4693 D. (Author).}
