The paper presents the results of a study of the radiation damage of stainless steel 10Х18Н10Т-ВД, which has the symbol EP-502. Radiation properties of steel were studied by the method of positron spectroscopy. The main structurally sensitive parameter was the probability of redistribution of positron annihilation between conduction electrons and bound electrons of matrix atoms. The object of the study was subjected to a complex effect of various factors. The main ones are melt processing of liquid metal lithium at 600 °C for 1000 hours from annealed, unstressed and stressed states. The next stage of the study was to study the structural characteristics of steel after saturation with hydrogen from these earthquakes. Lastly, metal was exposed to electrons and neutrons at fluences 10¹⁸ and 10¹⁹ cm^-2 at a temperature of no higher than 70 °С. The results of the investigations made it possible to establish the ambiguity of the influence of molten lithium on the radiation damage of stainless steel and its moderate aggressiveness on the corrosion processes of steel.

This work deals with the computer simulation of low- and medium energy (E₀=0.5÷10 keV) N⁺, Ne⁺, Ar⁺, Kr⁺, Be+ и Se⁺ions sliding collisions on the surface of a Cu(100), Ag(110), Si(001), SiC(001) and GaAs(001) solids, and of the accompanying effects, namely, scattering, sputtering and surface implantation. It has been shown that under these conditions the inelastic energy losses become predominant over the elastic ones. The anomalous energy losses observed experimentally at the grazing ion scattering by the single crystal surface were explained. It has been shown that from the correlation of the experimental and calculated energy distributions of the scattered particles, one may determine a spatial extension of the isolated atomic steps on the single crystal surface damaged by the ion bombardment. Results obtained can be also used to study short-range order in alloys undergoing ordering. Dissociative and non-dissociative desorption of adsorbed molecules were simulated. It was shown that at grazing ion bombardment the intensive nondissociative desorption of adsorbed molecules is possible. A preferential emission of Cu atoms in the case of Cu₃Au (001) surface sputtering is observed. It was shown that in the case of grazing ion bombardment the layer-by-layer sputtering is possible and its optimum are observed within the small angle range of the glancing angles near the threshold sputtering angle. The obtained results allow to select the optimum conditions for obtaining implanted depth distributions with demanded shape in narrow near-surface region (5–10 atomic layers) of crystals. The highly sensitive layer-by-layer analysis method was proposed on the basis of layer-by-layer sputtering mechanism.

The patterns of changes in microhardness and phase composition of Ni-Ti alloy in the martensitic-austenite state have been experimentally studied as a result of irradiation with ₈₄Kr¹⁵⁺ ions with the energy of 93 and 147 MeV at the temperature of ≤ 100 °С. It was established that irrespective of the energy of ₈₄Kr¹⁵⁺ ions, a complete radiationstimulated В19'→В2 transformation occurs during irradiation. It was shown that hardening of the modified layers increases with the energy of ₈₄Kr¹⁵⁺ ions and it is determined by hardness of NiTi austenite phase due to formation of the hardened radiation-introduced defective structures.

The patterns of changes in microhardness and phase composition of Ni-Ti alloy in the austenitic structural-phase state have been experimentally studied depending on the fluence of irradiation with ₈₄Kr¹⁵+ ions with the energy of 147 MeV. It was established that hardening with a maximum in the range of the projected range R_p and in the out-of-range region (h > R_p) increases with the growth of the irradiation fluence up to 5·10¹⁹ ion/m². It was shown that the reason of hardening is formation of the radiation-introduced hardened defective structures. The formation of nano-sized particles of the martensitic R-phase and the decrease in NiTi phase content with the B2 structure are also characteristic in the process of irradiation up to maximum fluence due to radiation effects.

The results of the investigation of the effect of mobile phone radiation on the formation of electron paramagnetic resonance (EPR) spectra and electromagnetic noise on the example of measurements of dental enamel samples for the low dose range are presented. To this end, spectra of irradiated dental samples were obtained. The spectra of ten samples irradiated in nominal doses of 0, 100, 200, 300 and 500 mGy in pairs were registered at different times with and without a mobile phone. The mobile phone was located near the resonator of the EPR spectrometer. Specially software was used to extract the radiation-induced signal (RIS) from the full EPR spectrum and determine its intensity. As mentioned above to study the effect of the mobile phone signal on the EPR signal in this study, the radiation signal (RIS) (standard deviation (SD)) will be estimated by the background signal and the residual amount. These parameters were obtained for single measurements and, on average, for four repeated measurements.

The paper presents the results of a study on the possible causes of differences in the structure and properties of the material samples of the FA`s cover (the screen type of the BN-350 reactor), depending on the temperature and duration of the post-radiation tests. It has been established that prolonged aging of the samples of the BN-350 reactor fuel assembly material up to 5000 hours leads to an increase in the concentration and size of carbide precipitates (such as Me₂₃C₆). It is assumed that changes in the microstructure: the grain size, the concentration of secondary precipitates, the displacement of carbides to the grain boundaries and their accumulation at triple junctions, occurs not only with an increase in the test temperature in short-time intervals (650–1050 °C isochoric annealing), and also in long-time exposure to high temperatures (5000 h, 400 °C, 600 °C, isothermally annealed).

The studied data shows that the subtype of meadow ordinary black earth soil on a chemical-ism salted corresponds to a sulphatic sort, and under the maintenance of readily soluble salts a kind, is characterized as not salted, and therefore they can be used for development of irrigated crop rotations.

In 2015 the main reactor systems were modernized, including complete replacement of the control&instrumentation system within the conversion of the reactor WWR-K to low-enrichment fuel. The new reactor core configuration became compact and more energy-intensive; the character of fuel burn-up has changed. The number of C&I operating elements and their geometric parameters have been changed.
According to the concept of the reactor WWR-K conversion, the water reflector is planned to be gradually replaced by beryllium one during the first year of operation, which is associated with the change in the neutron-physical characteristics of the reactor. This paper is intended to determine the kinetic parameters of the reactor WWR-K associated with the formation of the beryllium reflector. The correct operation of C&I assumes the input of the core kinetic parameters values into the system, such as effective fraction of delayed neutrons, lifetime of instantaneous neutrons. This paper is devoted to determining the values of these parameters and the dynamics of their changes during the reactor operation.
