Numerical Simulation Analysis of the Effect of Crud on Flow-rate Distribution of Hot Channel in Plate-type Fuel Core

With CFX code, the effect of crud on flow-rate distribution of hot channel in plate-type core is analyzed. The research shows that the flow-rate distribution of hot channel is decreased by 18.2%, on account of the clearance decrease 10% due to crud on the surfaces of both hot channel fuel plates in plate-type fuel elements core.
