The calculation of axial neutron flux distributions with the MCNP code at the JSI TRIGA Mark II reactor has been validated with experimental measurements of the (197)Au(n,γ)(198)Au reaction rate. The calculated absolute reaction rate values, scaled according to the reactor power and corrected for the flux redistribution effect, are in good agreement with the experimental results. The effect of different cross-section libraries on the calculations has been investigated and shown to be minor.
利用MCNP程序对JSI TRIGA Mark II反应堆轴向中子通量分布进行的计算，已通过对（197）Au（n，γ）（198）Au反应率的实验测量得到验证。根据反应堆功率进行缩放并针对通量重新分布效应进行校正后，计算得到的绝对反应率值与实验结果吻合良好。已研究了不同截面库对计算的影响，结果表明其影响较小。
