Irradiation experiments

Description

Irradiation experiments conducted in 1972-1973 in the OSIRIS reactor on fuel plates containing 93% enriched uranium are described. Eight plates contained UAl3-Al fuel with 35 wt% U (1.3 g U/cm3) and 43 wt% U (1.7 g U/cm3) and two plates contained U3O8-Al fuel with 43 wt% U (1.7 g U/cm3). The average burnup of the 235U was 58.5% and the maximum burnup was 70%. Results of the post-irradiation-examinations include data on dimensional measurements and metallographic examinations, the influence of grain size and the percentage of fines below 40 microns in the UAl3-Al plates with 35 wt% U, and the minimum temperature at which swelling appears with the occurrence of blisters after post-irradiation annealing. All of the tested plates behaved satisfactorily under irradiation. (author). 2 refs, 3 figs, 4 tabs
