Abstract: To meet the requirements of nuclear power control and simulation work, a method to achieve real-time interactive data between simulator 3KEYMASTER and Matlab/Simulink with shared memory was presented. This method used kernel system code Relap5 of 3KEYMASTER to carry out thermal hydraulic calculation, the program code was written to create the shared memory area by using the TASK procedure of 3KEYMASTER, then to use the shared memory area by using the S function of Simulink, ensuring the simulation synchronization of data interaction by using the Windows message mechanism, and the executing, pausing, resuming and preserving data of Simulink and 3KEYMASTER at the same time. The pressure control system model of once through steam generator was used to verify the accuracy of data interaction of interface procedure, 3KEYMASTER and Simulink were used to complete control and simulation systems, which have the same function. The comparison result has illustrated a good match between the two systems.

2.1 控制对象模型

RELAP5节点图如图5所示。一次侧冷却剂经过时间控制体128和129后，进入套管式直流蒸汽发生器，经单管区（控制体160、162）流入套管区（控制体163、164），再进入另一个单管区（控制体165、167），将热量传递给二次侧给水后，进入另外一个时间控制体172和173边界。每组蒸汽发生器的模拟都考虑了单管区和套管区换热，需要指出的是，实际的套管区外管是直管，内管为螺旋管，本RELAP5模型中外管和内管都用直管模拟，在稳态调试中，会对换热面积进行微调，以使一回路和二回路参数与额定值相符。二次侧给水经时间控制体180和182，向下流入单管换热区（控制体186、190），流过套管环形空间（控制体192），在进入另一个单管换热区（控制体194、196）后进入蒸汽管道。控制体548/550/556/558模拟主蒸汽管道，阀门555模拟蒸汽调节阀，时间控制体567模拟二回路蒸汽出口边界。
