The oxygen potentials and lattice parameter of oxide fuels (UO 2 and UO 2 -2 w/0Gd 2 O 3 ) irradiated in commercial BWRs have been measured by using a solid electrolyte galvanic cell technique and X-ray diffractometry. The fuel burn-up was 13-30 GWd/t for the former measurements and 6-35 GWd/t for t...
