| 摘 要： | 开发编制了基于输运理论的瞬态中子动力学程序DOT4-T.该程序是在二维稳态离散纵标程序DOT4.2基础上开发的,对瞬态中子输运方程中的时间变量直接应用无条件稳定的隐式离散格式.为验证该程序的正确性,对一些一维和二维瞬态基准问题进行了校核计算,其结果与基准题吻合良好.

| Abstract: | A transient neutron transport code for time-dependent analyses of neutronics systems, named DOT4-T, has been developed. The code is based on the Discrete Ordinates code DOT4.2, which solves the steady-state neutron transport equation in two dimensions. For the discretization of time variable, a direct method, the fully implicit and unconditionally stable time integration scheme, has been employed. The resulting code has been tested using several one-dimensional and two-dimensional benchmark problems, and the results obtained with DOT4-T shows very satisfactory agreement with the benchmark problem results. |
