Public support is one of the major challenges for maintaining a sustainable nuclear power program for any country. Although Bangladesh’s decision to build its maiden nuclear power plant (NPP) has received significant scholarly attention, the study regarding public perception is largely ignored. To fill this gap, this study investigated how Bangladeshis view the government’s decision to build NPPs. The study evaluated Bangladeshi youth’s knowledge, belief, and attitude toward the development of nuclear power. Applying the survey research technique, we found that 49% of the 450 respondents were positive toward NPPs, while 12% had no idea about NPPs. Women, in comparison to men, were found to have less knowledge of nuclear energy. Additionally, 41% of the respondents believed that the decision for establishing the country’s first NPP at Rooppur was right. However, 54% of the respondents expressed concerns over the safety, security, and sustainability of NPPs. Most importantly, a significant distrust among the respondents was observed in the capability of the regulator and operator for maintaining the NPP in a safe, secured, and sustainable manner. The study concludes that more policy actions are necessary to increase public support for nuclear power.
