AbstractMonte Carlo method is applied to assess the radiological risks to the environment. Determining the dose rates due to external radiation generated by radioactive inert gases when they are released from a nuclear power plant is discussed. The paper considers the estimation of volumetric concentrations of the released radioactive inert gases, and other characteristics associated with the use of gamma detectors of the automated radiation monitoring systems of the environment and unmanned aircraft radiometric system. In order to assure the reliability and the accuracy of the calculation by the Monte Carlo method for predicting the dose rates, the results are compared by this method with similar characteristics obtained by the integral method, which showed satisfactory agreement.

Abstractthis article studies the concept of safety and reliability of atomic energy from the angle of nuclear weapon non-proliferation regime. The main distinctive features of atomic generation compared with traditional sources of energy are highlighted. Basing on the selected features the current challenges to safety of atomic industry are presented and the main risk factors are introduced. Circulation of dual use items and sensitive technologies has always been raising extraordinary public attention whenever the nuclear energy is mentioned. Current technological progress allows people to elaborate new instruments for tightening of control on the nuclear non-proliferation regime. This paper goes through the main tasks of the Russian program of digital economy and its reflection on the nuclear industry. The features and advantages of blockchain technology application are examined. Basing on this analysis the concept of possible synergetic effect of introduction of blockchain into nuclear industry is discussed. Key features of blockchain might be widely applied in establishing of a control mechanism for tracking fissile material life path. The article brings into discussion the possibility of utilizing of a new digital instrument for tightening of control for movement of dual use items and sensitive technologies and by these means strengthening the nuclear non-proliferation regime.

AbstractThe safety of nuclear facilities is not possible without the use of access control systems at a radiation hazardous facility (ACS ROO). The article deals with the design and operation of equipment included in the ROO: turnstiles, radiation monitors, intelligent video surveillance, biometric scanners, etc. Measures to counter unauthorized actions of the offender at checkpoints are described, methods for detecting substances banned to penetration, electronic identity cards are described. The article provides options for protecting information assets from unauthorized access to the ACS. Prospects for the development of the ACS have been noted. Minimizing the role of security personnel with the corresponding development of the ACS functionality allows us to protect ourselves from mistakes or deliberate actions, reduce the time for monitoring access parameters, improve the quality of control while reducing financial costs, and provide effective counteraction to the prepared external and internal violator.

AbstractThe article performs experimental measurements of the induction of magnetic fields in the arc welding zone of 10 mm thick low-carbon steel. Calculation nonmagnetic zone bounded Curie isotherm is performed to account the magnetic field distortion of the magnetic material. Measurements of magnetic fields were performed without welding, with a digital gaussometer GM2. As a result, data of deformation of a four-pole magnetic field in the direction of welding and in the thickness of the part are obtained. It is determined that the displacement of the axis of the magnetic field and the violation of the magnetic field symmetry of the four-pole magnetic system takes place in the direction of welding.

AbstractThe article deals with method to characterize the identification of the state of the welding process based on phase portrait analysis. It is shown the various both recoverable and non-recoverable factors influence that process. The abilities of well-known statistical methods to identify such process were being analyzed. The article describes the algorithm to mine the phase portrait, its spleeting to states and estimation of identifying characteristics for each state.

AbstractIn this paper we present the results of numerical studies of control algorithms for the spatial distribution of the neutron field in the reactor core of WWER-1200 in the implementation of daily maneuvering regimes at NPPs with WWER-1200. The possibility of automated control of axial offset is demonstrated using one of the control groups with the aim of removing the psychological stress on operational personnel at nuclear power plants in maneuvering regimes. At the same time there is an additional minimization of water exchange while saving all nuclear safety parameters in the reactor core. The research is carried out on the basis of the PROSTOR software complex, which currently used in the Novo-Voronezh NPP to conduct training sessions with operational personnel of nuclear power plants and their training in optimal control algorithms for the power unit in maneuvering regimes. The methodology of adjustment of parameters of offset regulation depending on the neutron-physical characteristics of the core is proposed. The relevance of the conducted researches is related to the fact that for the NNPP-2 and LNPP-2 according to the NPP-2006 project in Russia it is planned to test the daily operating modes of the NPP with the power maneuvering in a wide range of their values. Verification of the operation of power units in such modes and their reliability will improve the competitive ability of NPP equipment with WWER abroad.

AbstractThe importance of monitoring the reaction time (RT) of the dangerous object managing operator directly during his professional activity is substantiated. The relevance of the use of RT automated controls is shown. The capabilities of the developed instrumental software tools for RT control are analyzed. The perspectivity of the instrumental software tools application is shown when creating automated testing systems, as well as assessing the level of acquired knowledge and skills.

AbstractThis article investigate the situational and personal factors of organizational and professional commitment to the safety culture of students of "Nuclear Power Plants: Design, Operation and Engineering" specialty. The paper uses the methods of sociological survey and data analysis. The findings suggest that students have the qualities necessary to form a commitment to safety at the individual level. The presented results of the study of the student motivational sphere reflect the importance of professional goal-setting formation as the basis of professional commitment and actualize the implementation of the safety culture principles as the basic corporate values of the nuclear industry.
