This article assays geographical research into nuclear cultures, and cognate conversations in atomic heritage, toxic waste studies, and memory and landscape studies, as one way to develop the notion of nuclear memory. In doing so, we survey how geographers and social scientists have sought to think and communicate memory of nuclear things through three specific modes: the archival, the aesthetic, and the speculative. Our central argument is that nuclear memory provides a theoretical orientation for geographers to engage with alternative possibilities for thinking nuclear waste futures besides anthropocentric notions of common sense.
