Abstract  

Photodissolution tests of UO2 sintered pellets were carried out in 3M nitric acid solution and at about 50 °C under UV irradiation. The light source was a Hg-lamp emitting a light of 254nm wavelength. In the products, chemicals such as H2O2 and NO2 ion were detected during photodissolution of the UO2 sintered pellets. Based on this result, a new dissolution mechanism of UO2 in nitric acid solution by photochemical reaction was suggested in this study.
