【摘要】：为弥补国内在由评价核数据出发计算中子比释动能(KERMA)系数和辐射损伤截面的程序方面的空白,建立了中子KERMA系数和辐射损伤截面计算方法,并基于FORTRAN-90程序语言开发了具有自主知识产权的中子KERMA系数和辐射损伤截面计算程序KDC。另外,针对能量平衡检查过程中发现的能量不平衡问题,提出了一种对不合理KERMA系数进行直接修订的方法,即用运动学上限替代不合理KERMA系数,并在KDC程序中实现了这一修订功能。通过将KDC程序与国际上广泛应用的核数据处理程序系统NJOY中的HEATR模块的计算结果进行比对,验证了KDC程序在计算结果和功能上的可靠性。
[Abstract]:In order to make up for the blank in the calculation of neutron specific kinetic energy and radiation damage cross section from the evaluation nuclear data, a method for calculating neutron KERMA coefficient and radiation damage cross section is established. Based on FORTRAN-90 program language, a program for calculating neutron KERMA coefficient and radiation damage cross section with independent intellectual property is developed. In addition, aiming at the energy imbalance problem found in the energy balance inspection, a direct revision method of unreasonable KERMA coefficient is put forward, that is, the upper limit of kinematics is used to replace the unreasonable KERMA coefficient. And in the KDC program to achieve this revision function. By comparing the results of the KDC program with the HEATR module in the nuclear data processing system NJOY which is widely used in the world, the reliability of the calculation result and function of the KDC program is verified.
