Description

Based on the passive residual heat removal system (PRHRS), according to one-dimensional model and equations depicting the distributing of temperature in the Density Lock on steady state, mathematic models of PRHRS are founded. Using Matlab code, the flux of the PRHRS and the outlet temperature of the heating tank are numerically conducted and the transient characteristics of the PRHRS after startup are analyzed. It is found that when the accident happened the cool water of the PRHRS may enter the heating tank and cool the heater down immediately, and it will set up steady natural circulation to remove residual heat in the PRHRS after a certain time. The distance between the heat-exchange and the heat-tank is longer, the ability of heat removal is stronger. (authors)
