A study of 1000MWe-class tokamak fusion-fission hybrid reactor

A fusion-fission hybrid reactor is considered the shortest way to realize the practical use of nuclear fusion energy since it can significantly mitigate engineering difficulties which pure fusion reactors face such as a large size of the fusion island and heavy neutron loading on the first wall. We studied basic requirements of a thermal fission light-water blanket as well as plasma and plant performance for a 1000MWe-class electricity-producing hybrid reactor. The results show that a 1000MWe-class commercial hybrid reactor can be realized at the same technology level as the ITER. (author)
