摘要：

The peculiarities of the cavitation effect are considered and some engineering criterion-parametric methods are proposed for estimating the possibility of manifestation and the level of intensity of the cavitation action on components of narrowing devices of circuit II of nuclear power plant (NPP) power units. Results of computational and experimental studies are presented which have shown that up to 30% of throttling devices of the condensate-feed channel of NPP power units are subject to the cavitation erosion. The possibilities of practical application of the developed methods were established for revealing the causes of wall thinning of narrowing devices in the NPP working channel and for preventing it. © Pleiades Publishing, Inc., 2012.
