Project Description

The Consortium for Advanced Simulation of Light Water Reactors (CASL) is a U.S. Department of Energy (DOE) Innovation Hub, established in July 2010 for the modeling and simulation of nuclear reactors. In 2016, the VERA Core Simulator (VERA-CS) was used to successfully simulate and provide high fidelity solutions to quantify the uncertainty in predicting the onset of Chalk River Unidentified Deposits (CRUD) growth and therefore allowed for more optimal operating conditions for current U.S. reactors. In 2017, CASL will use VERA-CS coupled to Shift, a Monte Carlo neutronics solver, to verify and validate the gamma heating distribution for a wide variety of operational states and accident conditions. These calculations will allow for determining the errors in the lower-order approximations used in VERA-CS and will enable predictive simulation of these operational states and accident conditions. Along with this analysis, CASL will also perform high-fidelity vessel fluence calculations using excore modeling with Shift and VERA-CS.
