Determination of tritium production in the liquid blanket of fusion reactor is necessary for the nuclear material accounting system. In this paper, an equivalent measurement method is proposed, which is based on measuring the isotope abundance of lithium before and after irradiation. Theoretical analysis of the feasibility of the method is carried out, including complex nuclear reactions of neutron and lithium, the influence of the lead matrix, and the influence of gradient of the lithium isotope abundance before and after irradiation.
