Abstract—This study evaluated the change of micro structure caused by the deterioration factors in the structure of nuclear power plant out of concrete structure. Because the nuclear power plant is influenced more seriously than general structures when the deterioration phenomenon occurs, the deterioration of its concrete should be reevaluated by the viewpoint of micro structure rather than by the existing deterioration evaluation method. Accordingly, this study estimated the diffusion behavior of toxic ion based on the mechanical properties such as concrete strength in order to develop an estimation model of time-based micro structure of the concrete used for nuclear power plants.
Index Terms—Nuclear power plant, concrete structure, deterioration, micro structure and mathematic model.
