铀氢锆反应堆脉冲参数分析

Analysis of Pulse Parameters for Uranium Zirconium Hydride Reactor

介绍了铀氢锆反应堆计算模型和程序，分析了反应性引入速率、反应性引入量、燃料瞬发负温度系数、燃料热容和瞬发中子寿命对脉冲参数的影响。计算结果表明，脉冲峰功率与反应性引入量的平方成正比；一次脉冲释放能量与反应性引入量成正比；燃料元件热容随燃料温度变化，脉冲峰功率和释放能量随燃料热容增大而增大。

The calculation modle and code are presented at first and then the influence of reactivity insertion rate,reactivity insertion,fuel prompt negative temperature coefficient,heat capacity of the fuel and prompt neutron lifetime on pulse parameters are analysed in the paper.It is indicated that the peak power for pulse varies as the square and energy released linearly with the reactivity insertion.The heat capacity of fuel varies as the fuel temperature,as well as pulse peak power and energy released can be increased by increasing heat capacity of the fuel.
