In this paper the optimal design problem of the diffusion-fission cross section for a dynamical reactor is considered on the basis of the simple energy static diffusion approximation equation. This problem, mathematically, can be explained as an inverse problem. The existence of the optimal diffusion-fission cross section and the corresponding optimality condition are given.

在快裂变反应堆的临界问题和超临界系统动力学过程的分析中,几何曲率有重要的应用价值。本文用变分法解析求解了均匀裸椭球反应堆的几何曲率,并给出了较详细的推导过程。作为结果的实际应用,我们还把它推广到非均匀裸椭球反应堆和具有无限厚反射层椭球反应堆的情况。解析结果与二维数值模拟结果作了比较,符合得相当令人满意。
