JSC "VNIIG. BE Vedeneyeva "carries out research to ensure the reliability and safety of most hydroelectric JSC" RusHydro ". One of the important and challenging projects in recent years has become a project Boguchan hydro capacity of 3,000 MW.
Boguchan hydroelectric power — a project for a truly unique even on a global level, not only in terms of technical solutions, but also from the point of view of the harsh climatic conditions in which they are applied.

According to the draft, the way Angara stood side by side, two dams — concrete and rockfill. In the body of the concrete dam for the first time in Russian practice applied stepped spillway, providing dissipation of energy flow in the drain lines and the slower rate in the downstream. Spillway has 50 steps, its overall height of 80 m stepped spillway design, adapted for use in harsh environments, has been proved by experts VNIIG on a specially created physical model. Also, during the construction of a concrete dam experts from the institute recommended the use of concrete increased mobility, have developed new formulations of concrete mixes and concrete technology. The name of the second part of the dam (rockfill) should not be misleading. It used a very complex technical solutions, and one of them — cast bituminous membrane, which serves to prevent the filtration of water through the dam. VNIIG. B.E.Vedeneva justified the choice of material, design and construction technology diaphragm, and subsequently carried out the scientific support (correction of the raw materials and recipes asphalt, refinement technology, methods, quality control, etc.) and research cores drilled from asphalt to conduct an independent quality control of the diaphragm. In the pre-launch period of construction experts from the institute surveyed metal water conveyance paths BoHPP — penstocks and spillway, gave recommendations to enhance their reliability, and after the necessary papers issued conclusions on preparedness structures for launch. For examination and repair work inside the penstocks used specially designed mobile platform. To date, most of the work behind, but scientists will continue the scientific support of the object, and in 2013 the meantime, work Boguchan plant is already gaining momentum. It will have many more years to transform the power of the Angara River in electricity for the region, providing its development. Reference All-Russian Research Institute of Hydraulic Engineering. BE Vedeneyeva founded in 1921, today it is a leading research center on hydropower, energy and hydraulic engineering. Main activities: — Comprehensive research on the scientific substantiation of a reliable and safe operation of hydraulic, thermal and nuclear power plants; — Studies related to the design and construction of hydropower construction in North-climatic zone and in a seismically active regions — Scientific and technical support under construction power plant; — Creating a regulatory basis — Special studies and the development of technical solutions for the unique buildings and structures for the development of hydrocarbon deposits on the continental shelf of the Arctic and on.
