Radioactive waste management: Societal challenges in the era of green nuclear energy

Abstract

Abstract Recently, there have been international debates over the idea of labeling nuclear power plants as a green investment. To be considered sustainable, to get a green investment label and to contribute to green growth, nuclear energy should be based on clear plans regarding safe disposal of radioactive waste. Final disposal of radioactive waste is witness to many disputes, one of the most important being that of public acceptance. Society represents a critical and a decisive stage in the process of radioactive waste management. Management and disposal process of radioactive waste requires community confidence and acceptance. The socio-political context must be addressed continuously through stakeholder commitment and public concerns. The final stage of radioactive waste management is especially characterized by population involvement, stakeholder availability, and mutual dialog. The objective of this study is based on finding the relationship between the location of a radioactive waste disposal facility (RWDF) and the perception of the population regarding various aspects related to nuclear energy and radioactive waste. A series of questions in the form of a questionnaire were used for data collection. A total of 200 valid questionnaires were used for this analysis. The study was focused on the Romanian population following a homogenous distribution throughout the country. Therefore, to better understand the issue, the paper investigates the correlation between the location of a radioactive waste disposal facility and a variety of factors, such as: attitude, perceived benefits, perceived risks, overall knowledge and perceived costs. Spearman rank correlation was used for data analysis. Bringing together theoretical information about nuclear energy and radioactive waste and the empirical data collected at the national level, this research study showed that the acceptance of a radioactive waste disposal facility is much stronger if the population is in favor of nuclear energy. As well, perceived risks create major concerns throughout the population and influence the location of a radioactive waste disposal facility. Cost aspects are controversial and create disagreements in relation with radioactive waste management options. That being said, this study brings value to the nuclear field by emphasizing the important societal factors which influence the location of a radioactive waste disposal facility in the green energy era.
