摘要

摘要: 金属型脉冲堆的反应性反馈效应主要由热膨胀引起，本文在反应性温度系数的基础上建立了波形计算方法，该方法由蒙特卡罗中子输运程序、热力学计算程序和点堆方程3部分组成。首先由三维中子输运程序和热力学计算程序计算出热功率和反应性的耦合关系，然后将耦合关系代入点堆方程，即可求解出波形。采用该方法计算了Lady Godiva的波形，计算结果与LANL的实验结果一致。

Abstract: The reactivity feedback effect of metal burst reactors is mainly caused by thermal expansion. The method of waveform calculation was built with MC neutron transport code, the thermomechanics program and point reactor neutron kinetics equations on the basis of reactivity temperature coefficients. The coupling relation between heat power and reactivity is got by means of the three-dimensional MC neutron transport code and thermomechanics program. The waveform is got by way of solving point reactor neutron kinetics equations including the coupling relation. Using this convenient method, the typical waveform of Lady Godiva was calculated, and the calculated results are consistent with the experiment results of LANL.
