浓缩回收铀的M级联的近似算法

Approximate Calculation Method of M Cascade for Enrichment of Recycled Uranium

浓缩回收铀最有效的级联形式是带附加供料流的级联,它以天然铀为主供料,回收铀为附加供料。基于回收铀浓缩的特殊性,提供一种用于浓缩回收铀的带附加供料流的M级联的近似算法。数值计算表明,近似算法与工程优化算法得到的结果非常接近,最大相对偏差不超过0.1%。近似算法相对于工程优化算法更简单、方便和快速。

The most effective cascade scheme for the enrichment of recycled uranium is the cascade with an additional flow, in which the natural uranium is supplied as a base feed flow and the recycled as an additional feed flow. Based on particularities in the en richment of recycled uranium, an approximate calculation method of M cascade for the enrichment of recycled uranium was presented. Numerical calculations indicate that the results obtained by using the approximate method and the engineering optimization method are very approach, and the maximum relative error is less than O. 1%. But com- pared with the engineering optimization method, the approximate method is more simple, convenience and faster.
