We implement a burnup calculation model by the MMPA method in SHIKOKU2 in order to improve the accuracy of the cooling calculation and to shorten the calculation time. We perform burnup calculation and cooling calculation using SHIKOKU2 after the model improvement, and we confirmed that the calculation time can be shortened with the same accuracy as the conventional method.
