摘要
采用反应堆孔道深穿透屏蔽计算的点探测器、DXTRAN球抽样方法,计算了西安脉冲堆径向孔道出口处中子、光子的注量率空间分布、能谱分布和角分布等重要参数,并利用相应的实验测量值,验证了理论计算的准确性,为该实验孔道应用及建立该孔道出口处平面等效源提供了理论依据。
Monte Carlo code MCNP/4B and deep duct penetration skill of point detector and DXTRAN sampling had been used to calculate the radiation field parameter of 1# radial duct at Xi'an pulsed reactor. The parameters such as dose, flux, angular flux, spectrum of neutron and photon were obtained, and the veracity of results was confirmed through comparing the experiment with the theory. This calculation work proved the theory foundation for anolication and surface source's simulation of this radial duct.
