The main stages and processes through which deposits are generated, migrate, and precipitate in the metal-secondary coolant system of power units at nuclear power plants are analyzed and determined. It is shown that substances produced by the mechanism of general erosion-corrosion are the main source of the ionic-colloid form of iron, which is the main component of deposits in a steam generator. Ways for controlling the formation of deposits in a nuclear power plant's steam generator are proposed together with methods for estimating their efficiency. © Pleiades Publishing Inc. 2011. Source

Principles used in the development of modern computation codes for calculating erosion-corrosion of power equipment are considered. Specific features of their practical applications aimed at preventing, revealing, and eliminating erosion-corrosion thinning of the metal of elements used in the units of power stations are analyzed. Results obtained from using the domestically developed computation code RAMEK for operating power units are presented and prospects for implementing it in designing new power units of nuclear power stations are determined. © 2011 Pleiades Publishing, Ltd.

We present data on the effect the pH value of liquid film has on the rate of erosion-corrosion processes in the metal of thermal and nuclear power station elements operating with two-phase flows. We also suggest a calculation diagram and an engineering procedure for determining the pH value of liquid phase in the wet-steam paths of power units depending on the concentration of corrective additions, steam wetness ratio, and temperature. © 2010 Pleiades Publishing, Ltd.

Analysis of the state and prospects of geothermal energetics development in Russia and foreign countries is carried out. Trends of improving the geothermal energy technologies are considered. An estima- tion of the development of promising binary power units for electric energy production by using low-temper- ature geothermal and other heat sources is given. The geothermal projects being dominant and best suited to be implemented in Russia are estimated. © Pleiades Publishing, Inc., 2012. Source

The results of additional field examination of pipelines obtained in the course of carrying out corrective measures at Russian nuclear power stations in connection with the event that occurred at the Mihama nuclear power station are analyzed. The role of these data and the possibility of using them in current and future works carried out by the OAO Rosenergoatom Concern on the problem relating to erosion-corrosion of the metal used in power units at nuclear power stations are shown. © 2011 Pleiades Publishing, Ltd.
