Abstract
A procedure for revealing factors causing damage to metal and the dominating mechanism through which this damage occurs that was developed earlier is applied for substantiating the operating conditions of valves with D nom = 800 mm installed in the multiple forced circulation loop of power units at nuclear power stations equipped with RBMK-1000 reactors under which their resistance to erosion is ensured. Operating conditions under which cavitation erosion may occur are established, and practical proposals on how to prevent damage to the metal of a throttle-control valve’s body are presented.
