摘要
本工作采用MCNP程序对样品在西安脉冲堆跑兔辐照系统内辐照进行了物理描述和临界计算,并采用MCNP 4C程序自带的微扰卡对样品引入的反应性进行了计算。计算结果体现出微扰卡计算微小扰动的特点,避免了常规算法中系统k计算偏差对计算结果的影响,计算结果更可信。
Physics description and criticality calculation were carried out for sample radiation in running system of Xi'an Pulsed Reactor based on MCNP 4C code in this paper. And the in-pile sample value was calculated with the perturbation card of MCNP 4C code. The perturbation card shows better results.
