In order to obtain new post irradiation examination data for validation of burnup calculation codes, isotopic compositions of 9 samples obtained from a 1717 high-burnup lead use assembly (53 GWd/t), which was irradiated in Ohi Nuclear Power Station Unit 4, were measured. The isotopic compositions were also evaluated by burnup calculations with SWAT4.0 code and compared with the measurements.
