摘要

建立了具有连续过相关的三维控制棒撤离反应堆事故的时空扩散方程。本研究的目的是观察控制棒抽离事故中反应堆的行为。通过线性减小三个时区的热吸收截面来模拟抽油杆的抽油过程。当吸收截面线性减小时，中子通量呈指数增长。当吸收截面一定时，中子通量呈缓慢线性增长。

Space-time diffusion equations for three-dimensional control rod withdrawal reactor accident

Space-time diffusion equations for three-dimensional control rod withdrawal reactor accident with SOR (Successive Over Relactation) has been done. This objective of this research is to observe behavior of reactor during control rod withdrawal accident. The rod withdrawal is simulated by linierly decreasing the thermal absorption cross-section over three time zones. When absorption cross-section decreasing linearly, neutron flux increase exponentioally. When absorption cross-section is constant, neutron flux increase slowly linier.
