Based on our calculation of the fuel temperature reactivity coefficient benchmark,it is quantificationally proved that MCNP with its own cross section library can t be used to simulate the reactor accurately and to calculate the temperature reactivity coefficient.
通过基准题的计算,定量地说明MCNP通过其自带的常温(294 K)下的核素截面数据库不能够对反应堆进行非常准确的计算(由于反应堆内各种材料/位置的温度不同),而且,它也不能够计算反应堆中与温度相关的量,如反应性温度系数。
