The Effects of Different Nuclear Reactions on Thermonuclear Burn-up Conditions of Deuterium–Tritium Fuel.

The effects of different nuclear reactions on thermonuclear burn-up conditions of equimolar mixture of deuterium–tritium are investigated. The minimum requirements are determined by three parameters: fuel initial density, initial temperature and hot spot size. The four-temperature theory is used to calculate the critical burn-up parameter or the product of the initial density and the minimum hot spot radius. It was shown that by considering the effect of all nuclear reactions, attaining the minimum conditions required for beginning of nuclear ignitions is faster than those cases in which the effect of reactions is considered individually.
