Abstract Monte Carlo calculations on the tritium breeding ratio in the blanket and the heating rate in the first wall were carried out for moving ring reactor, KARIN-1. The blanket adopted in this calculation consists of a 2-cm thick silicon carbide (SiC) first wall, a 25-cm thick lithium (Li) layer, and a 10-cm thick lithium oxide (Li2O) layer. It was found that the tritium breeding ratio in the blanket and the heating rate in the first wall are changing cyclically with a 1 s period. The maximum tritium breeding ratio obtained is 1.12, the minimum is 1.01, and the average value over a 1 s period is 1.10. As for the heating rate at the center of the burning section, the maximum is ∼26 W/cc, the minimum ∼10 W/cc, the average ∼ 15 W/cc, and the ratio of the maximum to the minimum is ∼2.6. The corresponding values at the entrance of the burning section are ∼24 W/cc, ∼4 W/cc, ∼12 W/cc, and ∼6.7, respectively. These results provide the basic information for thermal and mechanical design of the reactor system.
