Keywords:TRU waste, geological disposal, hull endpiece, C-14, inventory, activation calculation

A method for analyzing the leaching of isotopes from radioactive waste, such as the hull and endpiece, is currently being developed. The three-dimensional distribution of the isotope inventory was analyzed using Monte Carlo and burnup simulations, and the results were compared with measurement data.
