The Possibility of Tritium Self-Sufficiency in a Fusion Reactor

Based on modern data, analysis was carried out of the possibility of tritium self-sufficiency in a fusion D–T reactor. Taking into account the real losses of the tritium isotope during the operation of the reactor shows that at modern technologies and results of materials science studies, the self-sufficiency is impossible even at the maximum tritium breeding ratio $${{K}_{{\text{T}}}} = 1.9$$ .
