| Abstract | The article tells about the analysis of the use of environmental radiation control automation systems (Automatic Control System of Radiation Dose Level – ACSRDL) revealed that control methods performed by these systems along with current widely used instrumentation do not always allow obtaining information in the real time mode (on-line). In this article, for solving this type of tasks, we propose a new method, based on application of a set ("swarm") of unmanned aircraft (drones) randomly distributed in three-dimensional space, carrying a complex of equipment, which can then be used to solve a number of research tasks. It is shown, that to fulfill the research task, motion of the aircraft (drones) in the swarm should be arranged in some order. For this purpose, each drone is equipped with an electromagnetic generator with the directional radiation pattern in 4π and a detector. This equipment as well as special software allows prevention of an emergency situation such as collision of the carriers. Similar equipment can be installed on manned aircraft with a view to preventing accidents of the kind. |

| Abstract | It is shown that the vibration frequency of the main equipment of NPP with VVER-1000 falls in the frequency spectrum of the response corresponding to extending the maximum amplitude of the seismic action. It this work the results of the analysis of experimental data are presented. According to these results it follows that the logarithmic decrement of oscillations in the coolant may be less standardized to ensure seismic resistance values decrements for equipment and facilities. Expediency of full-scale experiments, under the impact of NPPs with VVER intended for decommissioning, artificially produced vibrations that simulate seismic and shock. |

| Abstract | This research is devoted to the reliable operation of electrodriving fittings (EDF) as one of important factors of NPP safety. In the article long-term experience of inspection of fittings by department of technical diagnostics of the Novovoronezhky NPP is generalized. For the purpose of diagnosing the current signals of the engines of 832 units of fittings were received when performing the operations "opening" and "closing". Thus, the EDF of blocks №№3,4,5 of Novovoronezhky NPP was surveyed. In the analysis of current signals so parameters as the duration of fittings operation, the difference between the duration of opening and the duration of closing, smoothness of a working course and the duration of the general backlash was determined by current. Discrepancy of these parameters to standard values is treated as a sign of malfunction of the equipment. Authors analyze tendencies of change of the condition of the equipment during 2011-2013. For the fittings which technical condition didn't change towards deterioration, change of category of repair with capital on current is offered. For fittings with natural considerable deterioration of technical condition replacement of procedural current control on capital is offered. |

| Abstract | The article tells about various malfunctions and sudden refusals arising in use of electrodriving fittings as a part of power units of NPP, it can lead to safety decrease and big economic losses. For definition of fittings technical condition on the nuclear power plant the analysis of spectrum and analysis of bending around the signal of the current consumed by the equipment in the course of work is applied. For the purpose of sensitivity increase of diagnosing the phase and plane method based on the analysis of a phase portrait of a signal of current is offered. It is shown that the best quality of diagnosing is reached when using the regular methods connected with the analysis of bending around and spectrum of current signals together with an assessment of phase portraits. |

| Abstract | The research tells about diesel-generator installation as the most important element of nuclear power plant safety system. Scientific research institute "Nuclear Power Mechanical Engineering" of Volgodonsk Engineering Technical Institute of National Nuclear Center of Moscow State Engineering Physics Institute within the contract with the Smolensk Nuclear Power Plant developed the working program of diagnosing of the diesel generator 15D100. In article the basic provisions of this program concerning the vibroacoustic analysis are stated. When developing approaches to diagnosing authors consider normative documents, features of operation of the diesel-generator equipment in the conditions of the nuclear power plant, generalize experience of diagnosing of the similar equipment in the transport sphere. Diagnostics on indicators of vibration covers all rotating equipment (pumps) entering into group of diesel-generator installation. Much attention in the article is paid to a choice of installation sites of vibration sensors. As methods of diagnostic data processing the preference is given to the spectral and сepstral analysis, the peak-factor and trend characteristics also are used. It is offered to estimate a deviation of the actual corner of fuel injection, wear of sealing rings, increase in a gap in a piston joint on bending around a vibration signal. Methods offered by authors have to provide reliable diagnosing of the equipment, detection of defects at early stages of development, forecasting of the diesel generator condition. |
