Power Plant Area Research Articles

In bilico tra terra e acqua. Visioni e rotte di collisione su un tratto di fiume Po

Caorso Nuclear Power Plant area is extremely representative of the central Po River territorial system, which is characterized by a profound conflict between impactful infrastructures and semi-natural environments with high ecosystem value. In this context, the decommissioning of the Power Plant transcends the local scale, triggering reflections about the resurgence of the nature and the need to rethink our lifestyles and how they impact the planet.Starting from the outcomes of LOL2023 International Workshop by Politecnico di Milano, the article proposes methodological reasoning to investigate the potential that this decommissioning phase opens. In particular, the text investigates three design principles that can potentially be used to transform the Power Plant’s ‘dying’ energy landscape into an inviting habitat for a wide community of living beings, without, however, scarifying the spatial quality lent by design.

Integrated Magnetic and Geochemical Assessment of the Soil from the Steam Power Plant Area of South Kalimantan Province

Abstract The magnetic proxy approach has proven to be efficient in the assessment of pollution by potentially toxic elements when targeting soils or areas with a homogeneous background where anthropogenic magnetic signals can be easily distinguished. It’s crucial to conduct research on the impact of fly ash on the vicinity of the PLTU in this particular area, as it’s a previously unexplored area. The unique thing about this research is that this PLTU uses coal containing Fe, Pb, and Mg as fuel and has a fairly high susceptibility value for fly ash and bottom ash. This study is due to an analysis of the magnetic susceptibility and heavy metal content in the soil of the area around the Asam-Asam steam power plant (PLTU) of South Kalimantan Province, where geogenic input and fly ash can influence it. Heavy metals that have passed the threshold at all locations are Ti, Cr, Mn, Fe, Ni, Cu, V, and Al. Most of the correlation coefficients are strong and significant between magnetic susceptibility values and heavy metal concentrations at each location. The correspondence between magnetic susceptibility values and heavy metal content reflects the potential of magnetic proxy methods at polluted spots, provided that the lithological conditions are carefully considered.

Detection and assessment of heavy metals concentration in wheat leaves collected from the vicinity of Sahiwal coal power plant, Pakistan, employing a modern data analysis approach

ABSTRACT Heavy metal pollution in food crops has become a global issue, especially in staple crops like wheat and rice. Electricity production utilising coal, ignites this issue in crops grown in the surrounding areas of coal power plants. Keeping this view in mind, the concentration of six heavy metals (HMs) Calcium (Ca), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Lead (Pb) and Magnesium (Mg) in wheat leaves have been assessed in this study. Fifty samples of wheat leaves have been collected from the surrounding areas of the coal power plant in Sahiwal. The samples were prepared using the wet digestion method (WDM). Finally, these samples have been sent for analysis via atomic absorption spectroscopy (AAS). The limit of detection (LOD) and limit of Quantification (LOQ) of AAS were calculated with the help of blank samples. The concentration of Ca, Cd, Cr, Co, Pb and Mg in wheat leaves were 1.0187 ± 0.549 mg/kg, 0.00484 ± 0.00403 mg/kg 00,416 ± 0.00334 mg/kg, 0.0534 ± 0.0351 mg/kg, 0.035 ± 0.018 mg/kg, 0.464 ± 0.200 mg/kg respectively. The concentration of all understudy metals was below the Food and Agriculture Organization/World Health Organization (WHO/FAO) standards except for Co, in one sample. However, the concentration of heavy metals may increase, which may have profound repercussions. Therefore, preventive measures should be taken in this regard. The neutrosophic approach has been utilised to examine the variation of the heavy metals content in wheat leaves. This study provides a solid scientific foundation for future appropriate actions and management of heavy metals contamination in food crops near coal-fired power stations.

Radiological characterisation of freshwater fish species from strategic locations in Bangladesh

A radiological assessment of inland freshwater fishes of wetland haor zones, near a uranium mine and Rooppur Nuclear Power Plant (RNPP) areas, was performed. Gamma spectrometric analysis showed the accumulation of 226Ra, 228Ra, and 40K in all studied fishes, with varying degree levels of concentrations. The average radioactivity levels of 226Ra, 228Ra and 40K in haor fish samples ranged from 2.76 ± 1.51 to 22.02 ± 3.81 Bq kg−1, 1.78 ± 0.69 to 21.53 ± 1.40 Bq kg−1 and 405.51 ± 22.04 to 749.80 ± 42.65 Bq kg−1, respectively. Conversely, the respective values for Bata fish samples of Rooppur Nuclear power plant sites varied from 2.66 ± 0.80 to 6.62 ± 0.81 Bq kg−1, 2.31 ± 0.62 to 5.18 ± 49.81 Bq kg−1 and 342.00 ± 4.98 to 461.45 ± 18.00 Bq kg−1, respectively. Activity levels of Taki fish (Channa punctatus) from haors zones were almost 3–4 times higher than the Meni fish (Nundus nundus) of the same locations and Bata fish (Labeo bata) of the RNPP site. The general public may attain doses of 244.54 µSv from the consumption of haor fish and 84.02 µSv from the fish of the RNPP sites yearly. The chance of an increase in cancer risk from intake of haor fish was higher than the ICRP values of 2.9 × 10−4. Univariate statistics showed that 226Ra and 228Ra radionuclides do not normally distribute, whereas 40K is normally distributed in the studied fish species. Multivariate statistical analysis demonstrated that the radioactivity and estimated radiological parameters are strongly positively correlated with 226Ra and 228Ra, and also positively correlated with 40K. Hence, it indicated that the contents in the freshwater fish species are usually controlled and influenced by similar geogenic sources and occur together. It is presumed that the radiological risk is mostly associated with and dominated by the uranium and thorium series and non-series 40K radionuclides in the freshwater fish species.

Strategy of geothermal energy development as a renewable energy source in West Java Indonesia

Background: Indonesia has vast renewable energy potential, including biofuels, biomass, and bioenergy from tropical biodiversity spread across the country. Hydropower and geothermal energy are the only forms of renewable energy used to generate electricity and are connected to the grid. Geothermal energy may be incorporated into the grid to create hybrid energy systems that will help to reduce the high energy demand while maintaining low energy costs and net present costs. There are now 14 biosphere reserves in Indonesia, divided into 24 units of core zones, six units of buffer zones, and 13 units of transition zones. The West Java Province has a geothermal potential of 6,101 MWe or 21% of Indonesia's total geothermal resources. Currently, the installed capacity of electricity from geothermal energy in West Java is 1075 MWe or 89% of the total national installed capacity of 1196 MWe. Method: This paper reviews West Java Province data collection from official government bureaus, state-owned businesses, and non-governmental organizations (NGO) reports on geothermal energy capacity, electricity installation, and used area of ​​geothermal power plant and will be limited to the years 2010 through 2020. The collected data will then be refined, extrapolated, and analyzed by the connected trend to aid in studying West Java geothermal growth and use SWOT method analysis. Finding: The result of this research is a strategy for optimizing the development of geothermal energy utilization. The strategies that can be developed are infrastructure improvement as an investment facilitation strategy, a strategy to leverage a costly investment and capital investment, underground mining in conservation forest areas to avoid degradation improvement and supervision of related institutions and stakeholders, implementation of environmentally sustainable development, and socializing programs and providing job opportunities for the local community. Conclusion: Indonesia has an enormous potential for renewable energy, especially geothermal, with West Java Province having the largest installed capacity. This study suggests strategies to optimize geothermal energy development, including improving infrastructure, investment facilities, underground mining, improving supervision, and sustainable development. Novelty/Originality of this study: Research on geothermal energy in West Java provides a comprehensive analysis and specific strategies to optimize the development of this energy in the area, including innovative underground mining approaches.

Presence of heavy metals in pulses and cereals ploughed adjacent to the Rampal power plant: a probabilistic health risk assessment

ABSTRACT In a recent study, we examined the concentrations of heavy metals, namely lead (Pb), arsenic (As), nickel (Ni), cadmium (Cd), chromium (Cr) and copper (Cu), in seven categories of food, specifically rice, wheat, maize, lentil, black gram, mung bean and pea (B-22). The ranges of Ni, Cu, As, Cd, Cr and Pb in the food items were 0–4.7, 1.1–8.5, 0.01–8, 0.001–0.2, 0–4.7 and 0–0.8 mg per kg fresh weight (fw), respectively. The estimated daily intakes (EDIs) of As, Ni and Cr exceeded the maximum tolerable daily intake (MTDI), stipulating that these elements potentially originated from dietary consumption. The cumulative risk {target hazard quotient (∑THQ)} associated with food consumption was found to exceed in rice and maize, indicating that non-carcinogenic risks from heavy metals in these two dietary items may offer possible health problems for the population. The hazard index (HI) value was 1.4 × 101, indicating that the food items may encounter detrimental health consequences. However, the carcinogenic risk (CR) linked with total As from most of the food items (rice, wheat and maize) exceeded the acceptable level. From a human health perspective, our analysis revealed that the studied food items were declared safe for residents living near the Rampal power plant area in Bagerhat, Bangladesh. However, the present results suggest that regular monitoring of these essential and toxic elements in food items as well as in soil and irrigation water around the study area is necessary to prevent excessive build-up of these elements in the food chain.

Stochastic optimization framework for hybridization of existing offshore wind farms with wave energy and floating photovoltaic systems

Due to the complementarity of renewable energy sources, there has been a focus on technology hybridization in recent years. In the area of hybrid offshore power plants, the current research projects mostly focus on the combinational implementation of wind, solar, and wave energy technologies. Accordingly, considering the already existing offshore wind farms, there is the potential for the implementation of hybrid power plants by adding wave energy converters and floating photovoltaics. In this work, a stochastic sizing model is developed for the hybridization of existing offshore wind farms using wave energy converters and floating photovoltaics considering the export cable capacity limitation. The problem is modeled from an investor perspective to maximize the economic profits of the hybridization, while the costs and revenues regarding the existing units and the export cable are excluded. Furthermore, to tackle the uncertainties of renewable energy generation, as well as the energy price, a scenario generation method based on copula theory is proposed to consider the dependency structure between the different random variables. Altogether, the hybridization study is modeled in a mixed integer linear programming optimization framework considering the net present value of the project as the objective function. The results showed that hybrid-sources-based energy generation provided the highest economic profit in the studied cases in the different geographical locations. Furthermore, the technical specifications of the farms have also been considerably improved providing more stable energy generation, guaranteeing a minimum level of power in a high share of the time, and with a better utilization of the capacity of the cable while the curtailment of energy is maintained within the acceptable range.

Monitoring For Elemental Composition Of Particulate Matter Deposited In Snow Cover Around Coal-Fired Thermal Power Plant (Karaganda, Central Kazakhstan).

Studies on thermal power plant areas with respect to chemical composition of particulate matter deposited in snow cover are limited. This study aims to monitor (2014–2022) particulate load and trace elements associated with the particulate matter distributed around (0.5-4.5 km) the coal-fired thermal power plant in Karaganda. In this study, snow cover was used as an effective scavenger of atmospheric pollutants. Using instrumental neutron activation analysis and atomic absorption spectrometry, the content of 26 elements and Hg, respectively, was determined in the particulate phase of snow. The results showed that particulate load varied from 26 to 1751, with mean of 427 and a background of 47 mg m-2 d-1. Anthropogenic impact caused a significant increase in content of U, Hg, Ta, Zn, Na, Cr, Co, Sr, Rb, Cs, Sc, Ca, Fe, Nd, Ba (2–30 times) in the samples compared to the background. Metal-bearing phases of Zn, Ba, As, U-Ta-Nb were detected through scanning electron microscope. The highest levels of particulate load (169–1032 mg m-2 d-1) and element contents in the samples were localized up to 0.7 km from the thermal power plant. The changes of particulate load and element composition of snow deposits during the monitoring period were connected with temperature, modernization of dust-collecting equipment, composition of coal and fly ash, long-range transport of emissions from other industries. The element content and metal-bearing phases in the particulate phase of snow can be used as markers for identifying emission sources from coal combustion.

Peyzaj koruma ve onarım açısından güneş enerji santralleri: İzmir’de yerel yönetimlerin faaliyetleri

Objective: The aim is to reveal depending on the location choices of solar power plantsthe landscape protection strategies and what needs to be done in terms of landscape restoration after the operations of the power plants are completed.
 Material and Methods: Seven solar power plants owned by local governments in İzmir constituted the main material of this study. In this context, observations were made in the research areas, the characteristics of the installed solar power plants were determined and their environmental effects were evaluated within the scope of landscape protection and repair.
 Results: The installation years, locations, installed capacity, and installation areas of the solar power plants, which are the subject of the research differ from each other. Therefore, their environmental impacts are different from each other. In order to evaluate the environmental impact, the profiles of the power plants within the scope of the research were examined by taking into account the standards of electricity generation from solar energy, and their distances to different uses and transportation axes were measured as bird flights. In addition, the areas covered by the installed power plants were revealed and the usage areas of the produced energy were specified.
 Conclusion: Five of the seven solar power plants examined within the scope of the research are assembled roofs and the other two are land applications. Since more space is required in the area preparation, logistics, and installation of solar power plants, which are land applications, the negative impact on the environment is higher. In order to prevent or reduce these negative effects, appropriate and comprehensive landscape repair plans should be prepared with conservation decisions for the solar power plant areas that are actively working, whose activities have been terminated and will be newly installed.

Analysis of Troubleshooting Effect on the Performance of Gas Engine G-102 B (TBG620 V16K) in Central Processing Area of PT. XYZ

PT. XYZ is a part of the largest oil and Gas Company in Indonesia, responsible for managing and developing oil and gas production activities in the East Java. The Central Processing Area serves as the facility for processing fluids produced from the East Java fields. The processed output consists of three phases: Gas, Oil, and Water. The operation of the Gas Engine G102-B TBG620 V16K running 24 hours a day to generate electricity at the central processing area of PT. XYZ requires regular maintenance, including scheduled preventive maintenance and unplanned or corrective maintenance. In the event of troubleshooting, such as a decrease in temperature in chamber 2B or a temperature sensor reading of 280 °C in that chamber, immediate corrective maintenance is necessary. Based on observations conducted in the power plant area, two possibilities causing the temperature decrease in that chamber were identified. The first possibility was the need for spark plug replacement, and the second was a malfunctioning temperature sensor resulting in incorrect readings. Therefore, the spark plug replacement was performed first, requiring a gas engine shutdown for approximately 2 hours for repairs. After the spark plug replacement, it was discovered that there was no change in the temperature reading in chamber 2B, which remained at 280 °C. Hence, the corrective maintenance performed did not have a significant impact because the issue was caused by a faulty temperature sensor. However, it was observed that there was a 1.16% increase in the generated power compared to before the corrective maintenance was conducted. The difference in power output could be attributed to variations in the quality of gas used in the combustion process of the gas engine.

Village road restoration in electrical steam power plant area in Banten, Indonesia through embankment reinforcement using geoframe technology

This paper presents a case study of the restoration of village road located between Zone 2A and Zone 2B after the excavation for box culvert underneath it. Geotechnical investigations showed that the area will be constructed upon volcanic rock material. The height of the Geoframe is approximately 19.7 meters. This system is a combination of polyester strip for reinforcing element and connected with clamp to the facing made of galvanized steel as a permanent formwork and non-woven geotextile material for filter element. The inclination of Geoframe structure can reach almost vertical with over 85⁰ inclined facing. The result of this work, Geoframe’s facing can be grown with vegetation (grass) to accentuate a natural and green structure. From design perspective, the embankment safety factor was above the criteria stated in Indonesian National Standard for Geotechnical Design Requirements which is above 1.50 and design with pseudo-static earthquake load which is above 1.10. The system has proven to be easy to implement in the field, fast and can be carried out with good quality control.

Geoinformation technologies of environmental monitoring in the Black Sea after Kakhovska hydroelectric power plant disaster

The article offers the implementation of the proposed approach to the assessment and forecasting of indicators of environmental monitoring of marine water areas. It is an important component of the process of information support for decision-making in the field of environmental safety. The south-western part of the Black Sea water area was as the test region, was suffered from a negative environmental impact of a terrorist attack by Russian armed forces in the area of the Kakhovskaya hydroelectric power plant. The attack caused the destruction of the facility and the leakage of water from the Kakhovska reservoir with catastrophic consequences for the Northern Black Sea region. The authors proposed to apply a combination of data from contact monitoring of hydrophysical indicators, remote sensing data and mathematical modeling based on geospatial data in the specialized geo-information software environment Delft3D Mesh Suite within the framework of the developed software component. The component provides for the automation of data collection and processing processes followed by modeling and forecasting and visualization hydrophysical processes in the water area. On the basis of the applied information technologies, an analysis was carried out and geomodels were built, describing the hydrophysical situation in the northwestern part of the Black Sea both before the disaster and after certain time intervals after it, like a week and a month). The dynamics of seawater salinity as an important indicator of the potential increase of biogenic substances in the composition of seawater, as well as the nature of the circulation of water masses, which can provide additional information about the features of the geographical distribution of pollutants in the area affected by the disaster, were analyzed. The need for further real-time ecological monitoring of the consequences of the disaster, especially in the most affected parts of the water area near the northwestern coast of the Black Sea and on the coastal areas of the land in this region with the implementation of the proposed information technologies, is substantiated.

SEISMICITY of the RUSSIAN PART of EAST EUROPEAN PLATFORM and ADJACENT TERRITORIES in 2018–2019

Seismic observations by 48 stationary seismic stations, including twelve temporary seismic stations located in the area of Novovoronezh and Kursk nuclear power plants, were carried out on the Russian territory of the East European Platform. A feature of seismicity in 2018–2019 is a unique Kandalaksha earthquake of November 5, 2019 with ML=3.8 in the Belomorsky region. Its focal mechanism was represented by a normal fault. For the first time, a noticeable earthquake with МL=3.4 was recorded on September 5, 2019 at the Pashninskoye and Beregovoye fields in the Timan-Pechora oil and gas province. It was felt in Neftepechorsk working settlement with an intensity of up to 4 MSK-64. As before, weak natural seismicity was recorded on the Baltic Shield: in Karelia, in areas bordering Finland, near the Kandalaksha Bay, near the Khibiny and Lovozero massifs on the Kola Peninsula, on the Voronezh crystalline massif territory, especially in the zone of its junction with the DnieperDonetsk trough.

ON RADON ACTIVITY OF TECTONIC FAULTS IN THE AREA OF SITING THE SINOP NPP IN THE REPUBLIC OF TŰRKIYE

Problem statement. The paper provides an additional expanded justification for applying an innovative methodology in the area of the future Sinop NPP, planned to be deployed in the Republic of Tűrkiye, to identify the activity rate of tectonic faults in soil foundation based on comprehensive radon measurements using the PSACEA universal estimation scale. The purpose of the article. Current radon activity assessment of existing tectonic faults in Earth’s crust based on archival measurements of soil radon carried out earlier in Sinop Province. Conclusions and results. Current analysis of radon measurement results obtained previously by the track method made it possible to further assess the radon activity rate of tectonic faults existing in the area of the future nuclear power plant. The proposed methodology to assess radon activity of tectonic faults in Earth’s crust involves increasing safety during the construction and operation of the future nuclear power plant. The regulation on using this methodology as part of the subsurface monitoring at the Sinop NPP can be enshrined in job descriptions. This methodology can also be used as part of the seismic monitoring of other sites at the nuclear power plant, especially those located in high seismic risk zones.

Comparative Analysis of Driver Mutations and Transcriptomes in Papillary Thyroid Cancer by Region of Residence in South Korea.

Radiation exposure is a well-known risk factor for papillary thyroid cancer (PTC). South Korea has 24 nuclear reactors in operation; however, no molecular biological analysis has been performed on patients with PTC living near nuclear power plants. We retrospectively included patients with PTC (n=512) divided into three groups according to their place of residence at the time of operation: inland areas (n=300), coastal areas far from nuclear power plants (n=134), and nuclear power plant areas (n=78). After propensity score matching (1:1:1) by age, sex, and surgical procedure, the frequency of representative driver mutations and gene expression profiles were compared (n=50 per group). Epithelial-mesenchymal transition (EMT), BRAF, thyroid differentiation, and radiation scores were calculated and compared. No significant difference was observed in clinicopathological characteristics, including radiation exposure history and the frequency of incidentally discovered thyroid cancer, among the three groups. BRAFV600E mutation was most frequently detected in the groups, with no difference among the three groups. Furthermore, gene expression profiles showed no statistically significant difference. EMT and BRAF scores were higher in our cohort than in cohorts from Chernobyl tissue bank and The Cancer Genome Atlas Thyroid Cancer; however, there was no difference according to the place of residence. Radiation scores were highest in the Chernobyl tissue bank but exhibited no difference according to the place of residence. Differences in clinicopathological characteristics, frequency of representative driver mutations, and gene expression profiles were not observed according to patients' region of residence in South Korea.

Occupancy model to unveil wildlife utilization at Yeongyang-gun wind farm management road, Korea

Wind power is a rapidly growing renewable energy sector that reduces greenhouse gas emissions and provides sustainable energy. However, environmental destruction in wind power plant areas, particularly in wind farms within forests, is an emerging issue. This study aimed to analyze the impact of wind-farm roads on terrestrial animals in forested areas. A camera trap survey was conducted to investigate the impact of road management on wildlife behavior. We installed 52 cameras along roads connecting wind turbines for three months (1st October to 30th December 2021) on the Yeongyang-gun wind farm in South Korea and evaluated animal occupancy and detection probabilities using an occupancy model. Factors related to terrain and vegetation were used to estimate the occupancy probability (station use). The detection analysis included the presence or absence of guardrails, wind turbines, shrublands, and retaining walls. Additional variables included camera type, number of camera-operating days, and survey time. During the survey period, seven terrestrial mammals (roe deer, wild boar, water deer, raccoon dogs, badgers, leopards, cats, and martens) were captured using cameras. Based on camera trap records, roe deer was the most dominant species, followed by wild boars, raccoon dogs, and water deer, with fewer badgers and martens. The presence of forests in the road area was a significant factor for most species in terms of use probability, and camera type was significant for detection probability. Detecting animals along roads shows that roads are passageways for wildlife, affecting animal behavior during vehicle movement and can cause habitat disconnection. Our results demonstrate that wind farms are indirectly linked to wildlife distribution and welfare. Effective management policies for mitigating wildlife disruption can support sustainable ecosystems and biodiversity. The results of this study can serve as a reference for supporting wildlife conservation, terrestrial ecosystems, and environmental impact assessments.

Microbial–Plant Collaborative Remediation of Cd-Contaminated Wastewater and Soil in the Surrounding Area of Nuclear Power Plants and Risk Assessment

The continuous development of China’s nuclear industry has caused an increasingly serious problem of heavy metal pollution in the ecological environment. A survey of the current situation shows that the quality of China’s groundwater bodies and their surrounding ecological environment has been severely affected. China has started to devote more attention to the issue of nuclear emissions and pollution. In view of this, this study takes an area contaminated by nuclear power plant emissions as the object of research and uses plant–microbe synergy to remediate the cadmium-contaminated environment. Cadmium-tolerant strains were isolated from the soil and identified as Serratia marcescens. The morphological characteristics of the cadmium-tolerant strains were observed with electron microscopy in the presence or absence of cadmium ions. The removal of Cd2+ from wastewater was analyzed in four experimental groups: Cd2+ removal from Cd2+-contaminated wastewater by combining a Cd-tolerant strain with Cd-flower, Cd-tolerant strain with Cd-flower, Cd-flower with alkali treatment, and Cd-tolerant strain with alkali treatment. This study innovatively treated Cd ion concentrations of 50 mg/L, 100 mg/L, 200 mg/L, and 300 mg/L. The results showed that the cadmium-tolerant strains were more densely concentrated in the treated Phyllostachys than in the untreated condition. This indicates that the Cd-tolerant strains were effectively enhanced by the alkali treatment of Phyllostachys spp. and that the adsorption of Cd ions to the Cd-tolerant strains was improved. In the presence of Cd2+ flowers only, the best removal of Cd2+ was achieved at a concentration of 50 mg/L, with a removal rate of 74.10%; the addition of Cd-tolerant strains resulted in a removal rate of 91.21%. When the alkali treatment was applied to the flat bamboo flowers, the removal rate was 84.36% when the concentration of Cd2+ was 100 mg/L. Then, when the cadmium-tolerant strain was added to the treated flat bamboo flower group, the maximum removal rate was 89.74% when the concentration of Cd2+ was 100 mg/L. The cadmium ion content of Cd2+ increased positively with increasing experimental time. In addition, the quasi-secondary correlation coefficients for cadmium ions in Lobelia were all greater than 0.9905, indicating that the adsorption kinetics were significantly correlated with the quasi-secondary kinetics. The analysis of heavy metal enrichment in Lobelia was divided into four groups, with Lobelia showing the best tolerance and cadmium adsorption capacity at a cadmium concentration of 20 mg/L. The results of super-enrichment coefficients showed that the enrichment coefficients of Lobelia ranged from 1.03 to 1.97, with values greater than 1. All these results indicate that the combination of cadmium-tolerant strains and plants can effectively remediate nuclear-contaminated soil and wastewater, thus improving soil availability and water regeneration, and improving the human living environment.

Development of nuclear power in Belarus: a sociological analysis of the elasticity of public opinion

The article discusses the results of sociological monitoring of public opinion on the use of nuclear energy in Belarus. The main part presents an analysis of the data obtained from the results of a sociological study conducted by the Institute of Sociology of the National Academy of Sciences of Belarus in 2022 on the assignment “Conduct sociological monitoring of public opinion of the population of the Republic of Belarus in order to form a positive attitude towards nuclear energy” of event 8 “Information and analytical support for the development of nuclear Energy in the Republic of Belarus” of subprogram 3 “Scientific support for the efficient and safe operation of the Belarusian nuclear power plant and promising areas for the development of nuclear energy” of the State Program “Science-intensive technologies and equipment” for 2021– 2025. The time intervals within which important events had a direct or indirect impact on public opinion about nuclear energy are characterized. A sociological method of calculation has been developed that makes it possible to trace the vector of public opinion’s response to nuclear energy (increase or decrease in the level of loyalty) to various internal or external factors. An assessment of the elasticity of public opinion about nuclear power is carried out with the construction of a typology of this elasticity. Also, self-assessments of the respondents’ formation and stability of their position regarding the implementation of the project “Belarusian NPP” were revealed. The need for systematic information and explanatory work among the population on all the main aspects of the practical use of nuclear energy is shown.
