Description

UO2 fuel fragments extracted from intact and defected irradiated CANDU elements were heated in air. The temperature range was 175 to 2500C for times in excess of 1200 h. Maximum pre-test burnups and linear powers were 190 MW.h/kg U (8000 MW.d/TeU) and 45 kW/m, respectively. Rates of weight gain varied from about 10-4 wt %/h to 2 x 10-2 wt %/h at 175 and 2500C respectively. All data are described by a process with an activation energy of about 130 kJ/mol. Irradiation and fragment size had significant effects on the rate of weight increase. The results have application to the station handling, transport and dry storage of irradiated nuclear fuel in the temperature range to 2500C. 6 references, 7 figures, 2 tables
