摇摆对自然循环核热耦合平均功率的影响
Influence on Natural Circulation Nuclear Thermal Coupling Average Power Under Rolling Motion
摘要
Abstract
By performing simulation computations of single-phase flow natural circula-tion considering nuclear thermal coupling under rolling motion conditions ,the influence factors which have great effect on the average heating power of this circulation system were studied .The analysis results indicate that under rolling motion conditions ,the average heating power which considers the nuclear thermal coupling effect is in direct proportion to the average flow rate and average heat transfer coefficient ,w hile it has an inverse relationship with the ratio between temperature-feedback coefficient of modera-tor and that of fuel .The effect of rolling parameters on the average heating power is related with the ratio between temperature-feedback coefficient of moderator and that of fuel .When the effect of the variation of the average heat transfer coefficient on the reactivity plays a leading role in the process , the stronger the rolling motion is , the higher the average heating power is .However ,when the effect of the variation for the average friction coefficient on the reactivity takes the lead , the stronger the rolling motion is ,the lower the average heating power is .关键词
