Keywords:JENDL-4.0, CASMO5, PWR, BWR, UO2 fuel, Burnup calculation, Measured isotopic composition

As part of uncertainty evaluation of the assembly nuclear calculation code CASMO5 coupled with a JENDL-4.0 base library, burnup calculations on PWR and BWR fuels irradiated in the domestic and foreign light water reactors were performed and the calculated isotopic compositions were compared with those measured to evaluate the uncertainty in the calculated isotopic compositions.
