About awarded research

After the accident at the Fukushima Daiichi Nuclear Power Plant, concrete used in nuclear power plants was contaminated by radioactive materials. Although some disposal or reuse of these concretes must be considered in the end, there are currently many unknowns regarding the interaction between radioactive materials and the concrete components, and it is difficult to estimate the amount of contamination. In the FY 2020 Research Program "Quantitative Evaluation of Long-Term Condition Change of Contaminated Reinforced Concrete Considering Actual Environment for Reasonable Disposal," many findings were obtained to solve these problems. This paper describes how radioactive materials, Cs and Sr, penetrate and interact with concrete, including cracks and cracked areas.

Your impression & future plan

We believe that the post-treatment of the Fukushima Daiichi Nuclear Power Plant accident, which is the background of this research, is an issue for which Japan must fulfill its responsibility. In particular, since concrete is a material available in large quantities, we would like to continue our research to respond appropriately to these issues.
