An Investigation of the Effect of Hydrodynamics of Flow on Erosion-Corrosion Resistance of Components of a Feedwater Control Assembly Used in Power Units of Nuclear Power Plants Equipped with RBMK-1000 Reactors

摘要

The results of computational hydrodynamic simulation of the flow of a working medium in the flow path of the feedwater control assembly used in power units of nuclear power plants (NPPs) equipped with the reactors of the RBMK-1000 type are presented It was established that the rate of control valve opening has an influence on the position of the areas of the intense local erosion-corrosion thinning of metal of the diffuser section downstream of the valve.
