The increasingly noticeable effects of climate change are leading to increased advocacy of nuclear energy. Even though the so-called nuclear renaissance has come to an abrupt halt, especially due to the Fukushima disaster, proponents of nuclear energy are promoting it as an inevitable solution to decarbonise electricity production. Yet it has been known since the 1960s that waste heat from nuclear power plants has devastating effects on river ecosystems. Despite the fact that countries like Germany and Switzerland have taken measures to limit the thermal load of the Rhine and Aare, the Rhine is still the most thermally polluted river in the world in relation to its water resources. This raises the question of whether the socio-technical promise of sustainability of the current nuclear power plants is at all tenable from a river perspective._x000D_

On this basis, this paper explores the (un)sustainability of riverine nuclear energy in past, present, and future, tracing its evolution over time from the early days of nuclear planning and construction to today’s – as of yet unfulfilled – dreams of a “nuclear renaissance”. We look at several European rivers that underwent nuclearization from the 1950s onwards, reconstructing the often-harsh struggles among a diverse group of actors for access to sufficient volumes of cooling water, the fight against “thermal pollution”, the negotiations about allowed temperature limits, and the emergence of technical fixes such as cooling towers and artificial lakes as – partly successful, partly failed – solutions to such problems._x000D_
