Electronic dispatch of energy consumption in a building with its own renewable energy - Smart house

In this study, it has been discussed methodically the control system of energy consumption from the power grid, generating electric energy on a seasonal basis (winter) heat load (thermocouples) and the utility of a set of renewable energy (solar photovoltaic, wind turbines and ground source heat pumps). It has also been taken into account the significant difference of energy network day and night consumption tariffs, seasonal heating load changes, solar insolation, and wind speeds. It has been figured out that the combined system of power supply at home, using the possibilities of the power system for the accumulation of excess renewable energy sources during the summer months, we can substantially simplify and reduce the cost of energy. The ability to use modern energy-saving equipment to simplify and reduce the consumer source system has been demonstrated. As well the new criteria for system optimization based on value analysis, the algorithm of complex consumer source control to implement a minimum cost supply at home, developed implementation flowchart of this algorithm based on modern microprocessor technology have been pointed out. © 2017 WIT Press

Morphology influence on water wettability of Mo back contact of solar cells.

Investigation of influence of Mo deposition on glass substrates by SIAD on its surface topography and wettability was conducted. We observe some steps in the process of film growth. Contact angle measurements showed that deposition of the Mo films on glass makes the surface less hydrophilic. It was indicated that with an increase of the irradiation dose, the roughness and contact angle increases rapidly at first and then decreases

Surface morphological properties of Mo-based thin films on glass.

Self ion assisted modification of elastomer and its micro- and macroscopic properties.

The composition of Zr-based thin films on rubber was investigated by utilizing the Rutherford backscattering technique and RUMP code simulation. The level of adgesion between the coating fabricated on rubber by means of self-ion assisted deposition was measured using Pin Pull Test. The coating deposited on the rubber consists of Zn, O, C, H. The self ion assisted deposition process may successfully control the level of adhesion of the coating to the rubber and causes strong modification of the macroscopic properties of the rubber surface

Optimal control of the system of coupled cylinders

We consider the problem of optimal control of a system consisting of two coupled cylinders. Such a system is a mathe-matical model of the nuclear fuel transfer mechanism at the nuclear power plant reactor. And also, such models are found in various robotic systems. We have obtained optimal control under certain assumptions on a controllable system. © 2018 Author(s).The research was supported by Russian Foundation for Basic Research, project no. 17-08-01385

Route optimization in the removal of radiation hazards

Route optimization is one of the types of jobs peculiar to nuclear facilities. For example, route optimization can be used as a way to minimize the radiation dose to personnel during the dismantling of dangerous radiation equipment. The sequence of jobs affects the total dose exposure of personnel. Also, in the solution of problems there are additional constraints in the form of precedence conditions. These conditions are due to technological constraints on the sequence of dismantling. This problem is similar to the well-known traveling salesman problem, but unlike the classic traveling salesman problem, the cost function depends on the list of outstanding tasks. A version of the method of dynamic programming has been designed to solve this problem and the appropriate software has been created. The developed software to provide estimates reduces personnel exposure in the optimization sequence of dismantling radioactive equipment. © 2014 WIT Press.International Journal of Safety and Security Engineering;International Journal of Sustainable Development and Planning;WIT Transactions on Ecology and the Environmen

Ecological features of fast reactor nuclear power plants (NPPs) at all stages of their life cycle

The future nuclear power industry should focus on the enhanced safety reactors such as inherently safe liquid metal fast neutron reactors. Many years of the operating experience from the BN-600 fast power reactor show that it has some advantages in terms of safety (the large amount of sodium in the reactor, large boiling point margin, etc). The safety systems have been improved in BN-800 which is under construction and further in BN-1200 project. Along with the design features of nuclear power plants, the overall safety culture including the optimization of radiation protection is very important. The UrFU in conjunction with the Rosatom enterprises works in this direction, dealing with the route optimization of work in radiation fields using dynamic programming techniques, optimization of the composition of the homogeneous protective materials for a given isotopic composition of radioactive contamination, the development of computer models of radioactive systems for training of the dismantling personnel. The management of the increasing amount of radioactive waste (RW) is the priority task of the nuclear power industry. Fast reactors allow it to minimize the amount of RW through the extraction of the fission products from the irradiated nuclear fuel while uranium and plutonium are returned to the reactor at a closed nuclear fuel cycle. © 2014 WIT Press.International Journal of Safety and Security Engineering;International Journal of Sustainable Development and Planning;WIT Transactions on Ecology and the Environmen

Elemental composition, topography and wettability of PbxSn1-xS thin films.

PbSnS thin films were prepared by hot-wall vacuum evaporation (HWVE). The Rutherford backscattering technique was employed for the investigation of PbxSn1-xS thin films composition.
