Abstract | The issue of detecting and preventing attacks on applications has been and remains one of the urgent tasks of information security. Flaws in the program code lead to disruption of the normal operation of the software. Data integrity, availability and confidentiality of the data, interruption of the execution of running processes or even the system as a whole may occur due to design flaws. The aim of this work is to prevent attacks on the application by overflowing the buffer using the developed complex to prevent attacks. To achieve this goal, the shortcomings of modern systems for preventing attacks on applications are briefly reviewed, the structure of the developed software package, the operation algorithms of each module of the software package, the mechanism for buffer overflows are examined, and the developed software package is tested on a simple buffer overflow. |

Abstract | The paper presents a study of the automated control system of the underwater radio-controlled unmanned vehicle (as a prototype) which monitors the radiation in the deepwater area bottom (with the depth over 10 m), and a system of the operator-vehicle communication line. A standard approach to the radiation monitoring is applied with the help of spectrometric and dosimetry equipment, as well as an echo sounder mounted on the underwater vehicle. The communication line with a facility located on the ground is exercised in the following two ways: when in water, it is arranged through the information transmission by ultrasound to the buffer gear floating on the surface of the water area, and through the gear it gets in a retransmission to the operator on the ground via a radio channel. The control of the underwater vehicle is exercised in the reversed sequence: from the operator to the buffer gear, it goes through a radio channel, then it goes from the latter to the underwater vehicle by the retransmission into ultrasound, and then it reaches the receiving device of the underwater vehicle through further retransmission |

Abstract | The article deals with the method of analyzing statistical data on failures to assess the reliability of units of the Unified Set of Technical Means (UCTM) at the Balakovo NPP. The calculations are carried out under a conservative assumption due to the lack of some data in the defect log. The analysis of the obtained data concerned the case of zero failures of some blocks during the observation period. The results show that these blocks are quite reliable to continue their operation. |

Abstract | All heat exchange equipment of nuclear power plants is subject to carbonate deposits, and especially strongly the one in which water circulates from the cooling pond. The appearance of contamination on the surface of the heat exchange leads to various consequences from a slight deterioration of heat transfer to premature wear of equipment. Increasing the thickness of contamination in heat exchangers at nuclear power plants also leads to losses of electrical power, and this is a direct economic loss. As a result, the problem of controlling carbonate deposits is very urgent and does not have a universal solution at present. The paper shows how heat exchange worsens in one month if no measures are taken. However, existing cleaning methods do not give 100% results and have their own disadvantages. This paper highlights the methods used for cleaning deposits, considers ways to increase their efficiency, and presents new ideas that were not previously used at nuclear power plants (including the Rostov NPP). These include increasing the efficiency of the ball cleaning system, reducing the salt content of the cooling reservoir, ultrasonic cleaning, and last of all, water magnetization. Their advantages over the existing ones are that cleaning is carried out during operation, there is no large waste for disposal, there is no probability of damage to the tubes, and they can be performed by the personnel of the nuclear power plant, which is less time and financial costs. The proposed ways are completely different, but they work for the same end goal, that is, to reduce pollution, reduce energy underutilization and eliminate lost profits |

Abstract | This article examines the role of safety culture and the direction of its formation to ensure the efficiency of the nuclear industry enterprises. There are two main categories to be analyzed – consciousness and self-control, it analyses their interrelation, mutual influence. We use a non-standard approach for this problem – the method of analyzing hierarchies. As a result of the calculations, a matrix of global priorities is constructed, which allows us to rank by significance activities aimed at overcoming destructive factors. The most significant event is considered to be the constant expansion of the information field. The results obtained should form the basis of a strategy for creating and improving the level of safety culture at nuclear power plants as the riskiest industrial facilities. |

Abstract | The paper discusses the benefits of developing and implementing a relational strategy in industrial enterprises. The authors interpret the report as «co-competition» necessary in modern conditions. This makes it possible to achieve long-term benefits both for economic entities experiencing a shortage of any type of resources, and for those who hold a fairly stable position in the market. Some results of approbation of the author's methodology are presented on the example of enterprises in Volgodonsk that manufacture products for the power engineering industry but are not part of the «Rosatom» State Corporation |
