Nuclear power is an increasingly common topic of conversation these days. In an age when the world is changing and society is turning towards its conservation, nuclear energy is key. Given the efforts to achieve the goals of the European Green Deal, more companies and countries are implementing corporate social responsibility in greater measures than before and increasing the positive impact on society and the environment. Corporate social responsibility is a concept that relates to the balance of social and economic goals of a company. Nuclear power plants are a specific form of company in which society puts greater responsibility to achieve CSR goals, and as such has a potentially greater impact on the environment around it. With strictly defined rules and norms different from other companies, it is ensured that this impact on the environment of a nuclear power plant would be exclusively positive.Through empirical research based on two semi-structured interviews with experts in the field of nuclear energy, and three case studies related to the operation of nuclear power plants in the Republic of Croatia as well as in two EU Member States, Germany and Finland, it can be concluded that the corporate social responsibility of nuclear power plants is a specific case of company in the world and that nuclear energy is crucial for the implementation of the green transition in the world.
