Accurately estimating the required tritium breeding
ratio (TBR) Lr in fusion reactor systems is necessary to
guide fusion research and development and to assess the
feasibility of fusion reactors as a self-sufficient energy
source. This is especially true when one considers the
limits imposed by the present-day breeding performance
of breeder blanket candidates. Studies of this subject have
