Burnup calculation of the HTTR considering temperature distribution and detailed burning regions was carried out using MVP-BURN code. The results show that the difference in k, as well as the difference in average density of some main isotopes, is insignificant between the cases of uniform temperature and detailed temperature distribution. However, the difference in local density is noticeable, being 6% and 8% for
U and
Pu, respectively, and even 30% for the burnable poison
B. Regarding the division of burning regions to more detail, the change of k
is also small of 0.6%
k/k or less. The small burning region gives a detailed distribution of isotopes such as
U,
Pu, and
B. As a result, the effect of graphite reflector and the burnup behavior could be evaluated more clearly compared with the previous study.
