CFD analysis of a direct vessel injection (DVI) transient to calculate AP600 reactor vessel shell temperatures

摘要

Computational Fluid Dynamics (CFD) was used to evaluate Reactor Vessel (RV) shell temperatures during a Direct Vessel Injection (DVI) transient for the Advanced Passive 600 mW Pressurized Water Reactor (AP600). The circumferential, axial andradial temperature distributions were calculated for the RV shell using CFD methods.
