| Abstract: | Possible replenishment schemes ensuring the attainment and maintenance of an equilibrium fuel composition are studied for a subcritical liquid-salt transplutonium burner reactor now under development. The computational model describes fuel burnup in a two-component approximation singling out the transplutonium actinides and the remaining actinide fractions consisting mainly of plutonium. The analysis is limited to instantaneous replenishment control, directly proportional to the criticality and/or fuel composition unbalance. The case of small fuel composition unbalance, allowing linearization of the burnup equations, and the general case where Lyapunov functions are used for stability analysis are studied. It is shown that criticality unbalance control using the transplutonium actinide fraction does not secure fuel-composition stability. Control using the plutonium fraction does secure stability.
