title = "AP1000{\textregistered} PWR startup core modeling and simulation with VERA-CS",
abstract = "This paper describes the application of the Core Simulator of the Virtual Environment for Reactor Applications, VERA-CS, under development by the Consortium for Advanced Simulation of LWRs (CASL) to the core physics analysis of the AP1000{\textregistered} PWR. The AP1000 PWR features an advanced first core with radial and axial heterogeneities and at-power control rods insertion to perform the MSHIM{\texttrademark} advanced operational strategy. These advanced features make application of VERA-CS to the AP1000 PWR first core especially relevant to qualify VERA performance. This paper focuses on the qualification efforts at hot zero power conditions, where Monte-Carlo reference solutions have been established. The comparison of both global core parameters (e.g. critical boron concentration, rod worth and reactivity coefficients) and fine-mesh fission rate spatial distribution indicate excellent numerical agreement between VERA-CS and the Monte-Carlo predictions across the simulations performed.",
