Calculating reaction rates and fusion power from neutron yields of fusion reactions that power future fusion reactors

By calculating the neutron yields of fusion reactions D(d,n)3He and T(d,n)4He, the reaction rates and fusion power were calculated in the range of fusion plasma temperatures inside the reactor core. Although it is essential to reactor performance, it is extremely difficult to measure the neutron yield of each fusion reaction independently and instantly. Therefore, accurate theoretical calculations of these neutron yields are required, and the Monte Carlo technique is the ideal method for achieving such calculations. In this work, the 3-D Monte Carlo code MCUNED was used to calculate the neutron yield of each fusion reaction within the operating temperature range of the reactor core. The optimum ratio of deuterium (D) to tritium (T) fuel mixture, fusion reaction rates, and fusion power ratio of fusion reactions were studied. The optimal operating temperature to achieve the best reactor performance (highest fusion reaction rates and highest fusion energy) was investigated.
