【Abstract】 The 200 MW NHR(nuclear heating reactor) RHRS(residual heat removed system) is numerically simulated by one dimension fluid dynamics model. The heat removed ability of 200 MW NHR RHRS and its influencing factors are analyzed. The area of air condenser and the height of air cooling tower in RHRS are the main factors influencing the residual heat removed ability , the height difference between the main heat exchanger and air condenser is the secondary factor.更多还原
