建立了多区变节点压水堆堆芯的数学物理模型 .在微机的运行环境下 ,运用FORTRAN 77语言 ,采用模块化结构 ,编制了一套可调可控多区变节点压水堆堆芯通用安全分析程序MRCPRS .程序将堆芯在径向划分为 3个区 ,在轴向划分为 6个控制体 ,可以根据用户的需要 ,灵活地改变分区及控制体的数目 .燃料元件分棒状和板状 ,用户可根据具体情况选择 .程序分别采用吉尔和阿当姆斯两类算法 ,研究并验证了堆芯稳态、瞬态各类运行工况 .经验证 ,程序计算结果正确 ,精度较高 ,可用来分析堆芯的安全特性、温度场的分布等
A mathematic and physical model of multi-zone variable-node PWR core was established.Under the computer operating environment, a set of adjustable and controllable multi-zone variable pressure PWR core General safety analysis program MRCPRS. The program divides the core radially into 3 zones and is divided into 6 control bodies in the axial direction, which can flexibly change the number of zones and control bodies according to user’s requirements. Plate shape, the user can choose according to the specific circumstances.The program uses Jill and Adams two types of algorithms, study and verify the core steady-state, transient various operating conditions.It is verified that the program is correct, the accuracy is more High, can be used to analyze the safety characteristics of the core, the distribution of the temperature field
