Abstract
The core simulator component of the Virtual Environment for Reactor Applications (VERA) that is being developed by the Consortium for the Advanced Simulation of Light Water Reactors (CASL) is coupled with the coolant chemistry code MAMBA to model CRUD-induced power shift (CIPS). Cycle 7 of the Watts Bar Nuclear Power Station Unit 1 is simulated, and comparisons are made with measured boron concentrations, axial offset, and 3D flux maps throughout the cycle. Cases are simulated with and without the effects of CRUD to show the axial offset anomaly between measured and predicted results normally associated with CIPS.
