“…However, along with the development of nuclear energy, there are risks of accidents at these facilities [6,7], as well as the risk of radiation impact on personnel [8,9], the population [10,11], the environment [12,13], and deterioration of surface water [14,15]. Prevention of such emergencies is based on environmental monitoring at the locations of man-made facilities and their preventive forecast [16,17,18].…”

Nuclear power plants (NPPs) result in accumulation of a significant amount of radioactive products during the process of their storage and the presence of a potential release of radioactive products, in the case of an accident that is a source of potential hazard and risk of radiation impact on the personnel, population and environment in general. The paper shows the microgalvanic corrosion element formed on the inner wall of fuel rods made of Zr + 1%Nb alloy and pellets made of uranium oxides, as well as the outer galvanic element of fuel rods and structural materials of the reactor made of steel of different grades. The hazards caused by corrosion damage and release of hazardous radioactive substances from the reactor based operating area are analyzed. The possibility of predicting the rate of corrosion damage using a mathematical model on the thermodynamic approach is determined and established.

“…Diverse human impact on the environment causes air pollution [Kustov et al,2019;Wierzbińska et al, 2002], disturbance of soils [Lazaruk et al, 2020;Kostenko et al, 2018] and deterioration of water bodies [Loboichenko et al, 2021a;Akhtar et al, 2021]. In addition to direct human activities in cities, additional negative impact is provided directly by man-made emergencies [Popov et al, 2020;Mygalenko et al, 2018]. At the same time, usually, on the one hand, there is environmental pollution [Popov et al, 2019], and, on the other, there is the additional cost of natural resources (often water) to eliminate them [Abramov et al, 2019;Dubinin et al, 2018].…”

“…The use of these substances exacerbates the problem of wastewater and soil pollution [7]. The problem of fire safety and environmental pollution is important for industry and society as a whole [8]. The reduction of fire danger in premises, the study of fire hazards and the development of improved fire automation systems are urgent directions of scientific research [9].…”

The object of research is the process of chemical transesterification of palm olein with increased oxidation indicators in the presence of potassium glyceroxide catalyst. Transesterification is an important method of fat modification. The use of fats with increased oxidation indicators leads to the deactivation of common catalysts and a decrease in the efficiency of the process. There is a need to increase the dosage of catalysts, increase the process temperature, which negatively affects the product quality. An alternative transesterification catalyst (potassium glyceroxide) was used for the transesterification of palm olein with increased oxidation indicators. Palm olein (CAS Number 93334-39-5) with standard indicators was used: melting point 22.4 °C, peroxide value 0.8 ½ O mmol/kg, anisidine value 0.3 c. u. Olein was subjected to heating at a temperature of 90 °C in order to increase oxidation indicators, after which it underwent transesterification. The difference in melting points of the initial and transesterified palm olein was used as a parameter of process efficiency. The maximum limit values of the oxidation indicators at which the process is effective are: peroxide value 12.7 ½ O mmol/kg, anisidine value 10.4 c. u. The difference in melting points is 12.1 °C, which indicates the efficiency of the process. The qualitative indicators of the obtained transesterified fat indicate compliance with DSTU 4336 (CAS Number 97593-46-9): melting point 34.5 °C, peroxide value 1.2 ½ O mmol/kg, anisidine value 1.0 c. u. The results of the research make it possible to use fat with increased oxidation indicators without pretreatment and predict the efficiency of transesterification depending on the fat indicators. This will increase profitability and reduce production waste.
