Radiochemical reaction products of T2/DT and CO under different tritium pressures

Abstract

The radiochemical reaction products of T2/DT-CO system with different tritium pressures were studied in this work. The results show that the pressure of tritium and reactant was the key factor affecting the reaction rate of T2/DT-CO system, and the reaction products were closely related to the initial tritium concentration. Gradual evolution of reaction products including multi-carbon and multi-oxygen organic compounds were jointly affected by tritium decay in reactant molecules and bond breaking of reactant molecules by β-rays released from tritium decay. In addition, the tritium concentration in the deuterium-tritium mixture also affected the reaction products. High tritium concentration was conducive to the formation of multi-oxygen organics, while low tritium concentration was helpful to produce multi-carbon organics.
