We are proceeding with the evaluation of nuclide release behavior from irradiated end pieces in geological repository. In addition to the evaluation by the conventional simulation, the radioactive concentration distribution of the irradiated end piece was newly measured using imaging plates. In the obtained distribution, a height dependence is confirmed. In the future, we will proceed with comparison with simulation.
