“…For example, they make a zero bid because of economic reasons. Protest bids are biased answers which can be further categorized as strategic bias or starting-point bias, among others [25]. In this research, the most common reason why group 1 did not want to pay was that there was not enough information to decide.…”

With the adoption of new technologies, more risk is introduced into modern society. Important decisions about new technologies tend to be made by specialists, which can lead to a mismatch of risk perception between citizens and specialists, resulting in high social cost. Using contingent valuation methods, this paper analyzes the relationship between willingness to pay (WTP) and the factors expressed through people’s image of nuclear power plants (NPP), their perception of NPP safety, and how these can be affected by their scientific background level. Results indicate that groups with a high scientific background level tend to have low risk perception level, represented through their image and safety levels. Further, the results show that mean WTP is dependent on scientific background and image levels. It is believed that these results could help decision makers address the mismatch of trust between the public and specialists in terms of new policy.

Background: As Egypt ventures into nuclear energy, ensuring the safety and security of its nuclear facilities is paramount. The ongoing construction of the El Dabaa Nuclear Power Plant (NPP) directs the necessity for Egypt to meticulously evaluate the potential outcomes of any conceivable accidents. A focused analysis on design-based accidents such as steam generator tube ruptures (SGTR) is imperative for assessing their impact on the local populace and the environment. Through comprehensive assessments, Egypt aims to enhance the safety protocols of its NPP. This preemptive strategy facilitates the identification and minimization of risk, along with the formulation of efficient emergency response frameworks. Such diligent preparations are essential for cultivating public confidence while ensuring compliance with international safety norms and securing the long-term sustainability of Egypt' s nuclear energy program. Materials and Methods:The hypothetical scenario of a SGTR at the El Dabaa NPP was modeled using the Radiological Assessment System for Consequence Analysis (RASCAL) code. This model examined the potential consequences of such an accident by incorporating meteorological data from 2013 to 2023 across all seasons to compute the source term, total effective dose equivalent (TEDE), and thyroid dose. Then, these metrics were evaluated against established safety thresholds to determine compliance. The outcomes of this analysis provide critical insights and aid in formulating strategies for effective response to an accident, especially if the calculated doses exceed the permissible limits. Results and Discussion:The analysis of the worst-case scenario for the SGTR accident at the El Dabaa NPP involves a U-tube breakage above the water level, exacerbated by a concurrent station blackout. This condition potentially leads to a considerable dispersal of radioactive materials, especially within a 0.4 km radius, with a TEDE reaching 4.80×10 3 mSv during autumn. However, the severity of this worst-case scenario fluctuates with seasonal weather conditions; notably in spring, the highest TEDE was 15 mSv at a 40 km distance. The source term distribution indicates that noble gases account for 31.6%, iodine group for 32.0%, and other sources constitute 36.4% of the total radioactive release. These findings confirmed that TEDE and thyroid dose exceeded the permissible thresholds, thereby highlighting the importance for protective measures to mitigate the potential risks of such accidents. Conclusion:A comprehensive assessment of SGTR accidents at the El Dabaa NPP emphasizes the critical necessity for stringent safety protocols and protective interventions in worst-case scenarios. By preemptively addressing these risks, Egypt can fortify its nuclear safety framework, emergency response capabilities, and adherence to global safety standards. This proactive stance not only assures the long-term sustainability of Egypt' s nuclear energy program but also solidifies public confidence.

The construction of a nuclear power plant in the Republic of Uzbekistan actualizes measures for the radiation safety of the population and territories of Kazakhstan. The aim of the study was to assess the radiation situation in the settlements of the Turkestan region located near the impact zone of the nuclear power plant. The investigation includes measurements of ambient equivalent dose rates of gamma radiation, equivalent to the equilibrium volumetric activity of radon and thoron in residential buildings, establishing the total alpha and beta activities, and measuring the specific activity of radionuclides in water soil and food samples. In soil samples taken from the villages of Zhetysay and Zhyly-su, the specific activity of 232Th is 2 times higher than the national average. The total alpha activity of drinking water samples from the village of Zhyly-su is 1,5 times higher than the maximum permissible concentration. The concentration of artificial (137Cs, 90Sr) and natural radionuclides (226Ra, 232Th) in food is within the normal range. Obtaining preliminary results of the research will make it possible to assess the predicted radiation doses for various age groups of the population, and to develop preventive measures during the operation of a nuclear power plant.
