The Nuclear Culture project of Ele Carpenter is the overarching title for her curatorial research into art and nuclear culture covering the full material trace of radioactive materials from uranium mining, energy and weapons production, decommissioning and waste. The curatorial process involves working closely with artists and a range of nuclear contexts, carrying out field research, commissioning new artworks, curating exhibitions and hosting roundtable discussions and symposia. The project started in 2011 when Carpenter was invited to talk about how artists might respond to submarine dismantling by the Submarine Dismantling Project Advisory Group (SDPAG) who were advising the British Ministry of Defence on how to take apart and store their old laid up nuclear submarines, some of which still have their old reactors on board. This article is a conversation between Maarten Vanden Eynde and Ele Carpenter about the urgency of nuclear visibility and deep time responsibility of radioactive waste in a period of increasing insurmountability.
