Abstract
Over the past several years, the Virtual Environment for Reactor Analysis, VERA, has provided a novel capability for the Consortium for Advanced Simulation of Light Water Reactors (CASL) to model crud-induced power shift (CIPS) in reactors operated by the Tennessee Valley Authority (TVA). While this developed capability in VERA is unique, multiple key parameters in the crud physics have remained unknown. The methodology employed here provides the capability to infer these key model parameters from measured plant data. Once the model parameters have been determined, a forward VERA computation is performed and results are compared to measured flux map data to determine the efficacy of the calibrated crud model.
