Description
Thermal diffusivity of simulated DUPIC fuel, which would be tested for irradiation at HANARO research reactor, was measured using the laser flash method in the temperature range from room temperature to 1623 K. Density of simulated DUPIC fuel used in the measurement of thermal diffusivity was 10.16 g/cm3 (94.2% of theoretical density) at room temperature, and diameter and thickness were 10 mm and 1 mm, respectively. Thermal diffusivity decreased from 0.0205 cm2/s at room temperature to 0.0060 cm2/s at 1623 K. Thermal diffusivity of simulated DUPIC fuel was lower than those of UO2 and simulated spent fuel. The difference of thermal diffusivity between simulated DUPIC fuel, UO2 and simulated spent fuel was large at room temperature, and it decreased as temperature increased. (author)
