本工作旨在模拟计算处于反应堆堆芯适当位置的杯形LiD靶室经热中子辐照后在腔室中形成的能量约为14MeV的中子场。通过采用蒙特卡罗多分支方法模拟中子-氚的联合输运过程,得到了腔室中的中子通量、能谱以及LiD靶室行处的沉积能量。 对于带有H2O反射层的装置,计算该层内的各区中子通量。经过比对,计算结果与实验数 The purpose of this work is to simulate the formation of a neutron field with an energy of about 14 MeV formed in the chamber by thermal neutron irradiation in a cup-shaped LiD target chamber in the reactor core. The neutron flux, energy spectrum and deposition energy at the LiD target chamber row were obtained by simulating the combined transport of neutron and tritium with Monte Carlo multi-branch method. For devices with a H2O reflective layer, calculate the neutron flux for each region within this layer. After comparison, the calculation results and the number of experiments
