One of the characteristics of HTGR is that HTGR has large temperature difference in a core. However, core burnup calculations of the HTTR by Monte-Carlo method had been performed with uniform temperature condition because of limit of calculation code and computational resource. Improvement of calculation code and computational resource enabled us to calculate with the temperature distribution in a core. We have performed burnup calculation of the HTTR with temperature distribution by Monte-Carlo code of MVP to evaluate power distribution quantitatively.
