The Analysis on Uranium Enrichment Product Abundance Control

Starting from the practical production and operation of centrifugal cascade, based on the value function formula, the expression of separation work loss due to abundance fluctuation in concentrate receiving container is drawed, which indicates that the abundance fluctuation will lead to the separation work loss in the concentrate container, and has a linear relationship with the total weight of concentrate, whereas a quadratic function relationship with the abundance fluctuation. It is also analyzed whether the variation of various factors causing the fluctuation of concatenated concentrate abundance will cause the change of separation work loss in cascade. The analysis shows that the parameter of change will influence the pressure and the flow rate of cascade internal unit, which will be readjusted automatically and enter a new steady state. As a result, the cascade deviates from the ideal condition, the separation capacity decreases and the mixed separation power loss increases accordingly. Therefore, the optimization strategy for the abundance control of concentrate flow products is put forward. In the actual operation in the future, the abundance fluctuation should be controlled in a given range, and the variation of parameters affecting the abundance of the product should be diminished as much as possible in order to reduce the loss of separation work.
