Non-Destructive Testing of Concrete Irradiated by Neutrons
Popis výsledku v původním jazyce
Two types of concrete samples were irradiated in Jeep II nuclear research reactor in Norwegian town Kjeller. Concrete cylinders were exposed to combined neutron and gamma radiations in order to determine their effect on concrete properties. Three different irradiation periods were employed to simulate various durations of nuclear power plant operation. Several destructive and non-destructive testing methods were proposed for post irradiation examination of concrete samples. One of the non-destructive testing methods was ultrasonic pulse velocity measurement. Radioactive samples were tested in controlled area, behind radiation shielding walls. Mechanical properties of concrete samples decreased by several tens of percent due to neutron radiation. The correlation between destructive and non-destructive testing results is provided in the paper.
