Abstract

Abstract

Considering the possible flow instabilities in the supercritical Water-Cooled Reactor（SCWR）, APROS has been applied to three different cases of density wave oscillations. The two-parallel channels, single channel and natural circulation loop are all numerical modeled and stability boundaries are obtained by dynamic simulation. Results show that the software APROS is capable of predicting the supercritical stability boundaries, which agree with other experimental and numerical results. For numerical analysis the time step should be refined. A large time step would bring along dissipative effects.
