摘要： Methods for strengthening soils under bases and foundations of buildings and structures with compaction of the base composed of weak mineral soils by determining the optimal design process parameters of the ground piles over the entire area of the base. The essence of the invention is that the method of compaction of bases composed of weak mineral soils that includes formation of a well, filling each well with the compacting material, and creation of a compacting effect on the compacting material by the hollow tubular working tool to form a ground pile. Preliminary engineering and geological surveys of the base area is performed to determine the values of the modulus of deformation, the Poisson's ratio, the internal friction angle, the specific cohesion, the specific gravity, and the initial void ratio of the weak mineral soil.

摘要： The invention relates to safe operation support systems of nuclear power plants (NPPs) at severe accidents, including methods and systems for cooling and cooling control of the reactors molten core. The invention increases safety of NPP and cooling efficiency of the molten core of a reactor. The invention increases the efficiency of cooling the molten core of a reactor by safely removing the heat load from the molten metal mirror, ensuring the elimination of vapor explosions. The invention changes the principle of cooling the reactor molten core, in that after the molten core destroys the reactor vessel, the conditions for subsequent cooling of the molten metal are determined by the characteristics of the trap casing, but not of the reactor.

摘要： A method of corrosion rate control of nuclear power plants process circuits equipment. The electrochemical potential of the structural material of heat exchanging tubes and the specific electrical conductivity of blowdown water in steam generators are measured, the polarization resistance of the structural material of the pipelines of the condensate-feeding path and the specific electrical conductivity of feed water in steam generators are measured, and these parameters are automatically averaged and compared with the rated values, which determine various degrees of corrosion activity in relation to the material of pipelines of the feed water circuit in steam generators. Depending on the data comparison, no actions are taken, coolant parameters are adjusted, or the power unit is shut down.
