Lateral expansion and impact toughness correlation of VVER-1000 reactor pressure vessel materials
Impact toughness and lateral expansion of the irradiated surveillance specimens for VVER-1000 reactor pres-sure vessel have been defined using Charpy impact test. The analysis of experimental data has revealed a linear correlation of these characteristics. It was shown that a slope of the regression...

| description | Impact toughness and lateral expansion of the irradiated surveillance specimens for VVER-1000 reactor pres-sure vessel have been defined using Charpy impact test. The analysis of experimental data has revealed a linear correlation of these characteristics. It was shown that a slope of the regression line is practically unchanged due to irradiation. Using the upper shelf energy test data it was also demonstrated the lateral expansion and impact toughness decrease simultaneously under the neutron irradiation. |
