| 要旨 |
In order to study the radiation effects on concrete structures in nuclear power plants, irradiation experiments using cylindrical specimens have been proposed. However, due to the high temperature in the center caused by gamma-ray, chemical changes in the material must be considered. In this study, a hollow specimen was proposed to reduce the internal temperature, and after predicting the temperature distribution of the hollow specimen, the physical properties of both specimens were compared by analysis that takes into account the aggregate expansion due to neutron irradiation by RBSM. |
