The AP600 is a simplified advanced pressurized water reactor (PWR) design incorporating passive safety systems that perform the same function as the active emergency core cooling systems (ECCSs) on the current
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...
