The paper considers the leakage of the radionuclide of nitrogen 16N7 (Т½=7,11 с, E,max= 6,134 MэВ, ν,max = 69%) arising in the 1st loop of the KLT-40 reactor used on icebreakers and floating units (PEB), through the steam generator to the second circuit into which water flows under pressure Pв, with temperature Тв, heats up with the formation of radioactive steam, the output of which is carried out through the spiral steam line of steam generator under high pressure Pп. The content of the specified radionuclide in a pair can be detected and assessed by applying the methods of -radiation spectrometry, measuring the volumetric -activity of steam, measuring the dose rate of -radiation of steam and using a computational model using a simple mathematical apparatus to determine the leakage region. The work identifies the main areas in the design of the steam generator, which can be used to measure radiation characteristics and methods for their assessment. 

The relevance of the work is determined by the fears of the population about increasing radioactive parameters of the environment in the area where the Rostov NPP is located. The methods of regression analysis are used to study the dynamics of the average and maximum values of the total β-activity of the near-surface air layer and atmospheric deposition obtained during state radiation monitoring. It is shown that the operation of power unit No. 1 for 17 years and the commissioning of new units did not lead to an increase in the analyzed parameters. The analysis of data on locally produced food products showed that the observation area of the Rostov NPP, as well as the Rostov region as a whole, does not have higher content of the main long-lived technogenic radionuclides 137Cs and 90Sr in comparison with the Volgograd region. The values of the total β-activity of food products grown on the territory of the nuclear power plant are below the «zero background» indicators.

The continuity preservation of the rocket solid-propellant engine body elements and the intermediate compartments construction units thrown by detonation products is unlikely. The paper considers damaging effect of the construction units of the rocket solid-propellant engine, thrown by the detonation products of different form fillers. The pressure in the shock-wave front arising in the outer plant layer upon impact by filler shell fragments is estimated.

The paper discusses the issues of testing the crane and the rise of the reactor vessel. These technological procedures are associated with the influence of the crane on the shell. The consequence of this effect is the partial destruction of the shell wall which is expressed by the formation of cracks on the outside of the shell. A proposal on the need to organize monitoring both at the construction stage and at the stage of shell operation is made. It increases the NPP safety

The paper considers various schemes of placement of the burnable absorbers (BAs) in the system of compensation of excess reactivity in the reactor of WWER type at the extended campaigns for the purpose of decrease in the maximum concentration of the boron absorber. On the basis of the variant optimization the influence of the method of placing the burnable absorber in the fuel rods (homogeneous and heterogeneous) and the amount of the placed burnable absorbers in them on the maximum value of the reactivity reserve compensated by the boron control system are analyzed

The article considers the possibilities of using production logic in dismantling works during the decommissioning of nuclear power plant units. The advantage of the logistic approach in the organization of dismantling works interconnected with the subsequent operations of handling dismantling products is shown

The article provides a brief overview of the effect of various separation schemes in horizontal steam generators (PGV) of nuclear power plants on the quality of steam produced in the steam path for supply to the turbine. A further increase in the thermal power of the PGV without a significant increase in the overall dimensions is determined by the «retention» of the separation characteristic of the PGV within the limits specified by the dryness of the steam taken. In this direction the key optimization of horizontal PGV should be considered the rejection of louvered separators in favor of steam-receiving perforated sheets with variable perforation and the development of a new thermal-hydraulic scheme for the two-loop WWER-TOI project.

A comparison of results of calculation of acoustic standing waves frequency with auto spectral power densities of the sensor signals of pressure fluctuations for complex combinations of acoustic elements of the 1st contour of nuclear power plants with WWER-440 is provided. The results of calculation of acoustic standing waves frequencies are found to be in satisfactory agreement with the measurement data. The new approach to calculate the acoustic characteristics of combination of number acoustical elements in the coolant system of the WWER-440 is worked out. The reactor with cold and hot pipelines as a complex Helmholtz resonator was studied for the first time. It is established that the frequencies of acoustic standing waves depend on the number of acoustic elements contained in the supply and discharge pipelines taken into account in the calculation

This article presents the results of a numerical study of ways to increase the reproduction rate of fast reactors with oxide fuel and sodium coolant. The purpose of this work is to study and detect fuel or fuel combination with the best technical and economic indicators for the BN-800 reactor facility which will increase not only economic indicators but also the efficiency of the entire pre-reactor cycle. Since over time the problems associated with a decrease in the amount of U235 which leads to an increase in its price and an increase in the amount of accumulated Pu which in the initial time is obtained in the framework of the military industry, worsen throughout the world. But today there is a need to look for ways to compensate for these phenomena with the priority of reliable and safe operation of a nuclear installation from the reprocessing of spent nuclear fuel (spent nuclear fuel) from WWER and RBMK. The paper examines the effects of several important factors on the performance of the reactor and on economic performance. These factors are the use of different fuels and fuel combinations, the geometrical dimensions of the reactor, the distribution of enriched fuel in the core, as well as the change in the specific volume of fuel within the permitted limits. 

Modern technical diagnostics allows to inspect equipment by numerous methods of non-destructive control, which complement each other and increase the veracity of the technical condition grade. The combination of large quantity of diagnostic data and different diagnostic methods go to the need to integrate diagnostic information streams in a single information system which automates the collection and processing of diagnostic parameters. The specialists of “Rostovatomtekhenergo” designed and implemented the information system with the necessary properties
