摘要
分别计算了燃料温度、控制棒棒位、铀重量比、燃料棒半径和燃耗对瞬发负温度系数的影响,并且对结果进行了理论分析。研究表明:对于铀氢锆堆瞬发负温度系数,起主要作用的是铀的重量比、燃料温度和控制棒棒位,其次是燃料棒半径,而燃耗的影响较小。
The influence of fuel temperature,control rod position,weight percentage of uranium,fuel rod radius and burnup on prompt negative temperature coefficient are calculated respectively in this paper,and then the results are analyzed theoretically,indicated that for prompt negative temperature coefficient of uranium zirconium hydride reactor,weight percentage of uranium,fuel temperature and control rod position are primary,fuel rod radius is secondary,the influence of burnup is very small.
