均匀裸堆单组扩散方程的普遍解及其分析

在现行核反应堆理论文献中,对有奇异源时中子扩散方程的解讨论甚少,本文对此作了补充,并给出普遍解公式。这对于深入了解有奇异源时堆的临界行为和中子通量的时空特性,以及堆在次临界启动时的物理性能,均具有重要的参考价值。

General Solution and its Analysis of One-Group Diffusion Equation in a Bare Homogeneous Reactor

In present references of nuclear reactor theory,the solution of neutron diffusion equation with singular source has been discussed very little. This paper supplements above problem and deduces the general solution formulas. It is highly important for us to understand thoroughly critical behaviour of reactor,time-space dependence of neutron flux and physical property during subcritical reactor startup with singular source.
