Abstract Electrochemical corrosion of lower-activity spent fuel simulants, SIMFUELs, has been investigated in support on-going analogous studies a real AGR nuclear electrode. Two electrode coupling methods have investigated, to study the sample 25 GWd/tU SIMFUEL pellet 20/25/Nb cladding replicate setup. Method-1 involves individual standalone electrodes, while Method-2 and within same For both ...
