What is it like to visit the inside of a nuclear power plant? Based on autoethnographic observations at nuclear facilities in seven countries, this article suggests that we as visitors are subject to two parallel rituals: a meta-ritual of security, and a main ritual of performing the nuclear facility as safe. This is done, first, by designating the visitor as unknowing, second, by showcasing the nuclear facility as over-secured, and third, by creating relational trust in the plant staff's expertise. Given the high numbers of visitors to nuclear facilities worldwide and over decades, these visits are not a neutral activity but an arena where persuasive emotional registers are employed to affect individuals and, by extension, influence broader societal formations of nuclear politics.
