In the core of the HTTR, there is large temperature difference. However, the core calculations of the HTTR by Monte-Carlo method have been performed with only uniform temperature condition. Then, we have performed first full core burnup calculation with temperature distribution by Monte-Carlo method. As a result, we have revealed the effect of temperature distribution.
