铀氢锆堆栅距对堆芯物理性能的影响

Influence of Pitch on Physical Behavior of Core forUranium Zirconium Hydride Reactor

使用铀氢锆堆（即脉冲堆）物理计算程序包ＰＲＰＳ，首先计算了栅距对有效增殖因子的影响、栅距与堆芯温度系数的关系，然后计算了由中国核动力研究设计院设计建造的我国第一座铀氢锆反应堆的冷却剂温度系数、燃料温度系数和等温温度系数，并且与实验值进行了比较，结果表明两者符合得相当好。

Influence of pitch on effective multiplication factor and temperature coefficient of uranium zirconium hydride reactor are calculated primarily by meane of physical calculating code PRP S for uranium zirconium hydride reactor,and then coolant temperature coefficient,fuel temperature coefficient and isothermal temperature coefficient of first uranium zirconium hydride reactor designed and built by nuclear power institute of china are calculated,in comparison with experimental value,calculating result agree very well with experimental value.
