•The kinetic model of heavy water radiolysis, including segregated and lumped models, was developed.•From the safety point of view, the segregated model overpredicts the amount of produced deuterium and oxygen in the gas phase compared to the lumped model.•Adding deuterium to heavy water at an optim...
