CFD Analysis of a Direct Vessel Injection (DVI) Transient to Calculate AP600 Reactor Vessel Shell Temperatures

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 and radial temperature distributions were calculated for the RV shell using CFD methods.
