Embodiment Construction
[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0028] The present invention provides a cross-dimensional coupling method for passive containment waste heat removal system of PWR, the specific method is as follows:
[0029] Step 1: According to figure 1 Schematic diagram of PWR passive containment waste heat removal system Use any known one-dimensional thermal-hydraulic calculation and analysis program of nuclear power system, such as RELAP5 program, TRAC program, RETRAN program, to establish passive containment waste heat removal system model. The passive containment waste heat removal system model includes the heat exchanger calculation model, the ascending pipe model, the descending pipe model, the heat exchange tank model and the water exchange tank water supply model, so as to simulate and calculate the passive containment waste heat removal system after it is put into operation. The ke...
