Abstract
By using the program STEADY-LHTR, the stability of two-phase flow system of a 200 MW nuclear heating reactor being designed by INET. Tsinghua University, has been studied. This article describes the instability of Ledinegg and multichannel oscillation and its mechanism. A great deal of calculations and analyses for flow characteristics, which are shown by figures and tables, of the 200 MW nuclear heating reactor with natural circulation system have been completed. The results show that the natural circulation flow rate in the 200 MW nuclear heating reactor is slightly increasing with the core inlet temperature rising, under nominal operating conditions the flow has good stability. However, as the core inlet temperature approaches to 155 c degree at 2.0 MPa pressure the Ledinegg instability and multichannel oscillation instability will occur in the natural circulation system of the 200 MW nuclear heating reactor.
