Abstract
The small land footprint of nuclear power has been one of its attractions, especially in comparison to land-intensive renewable energy sources that have begun entering widespread use. But what happens to that footprint when nuclear accidents are included? Adding the land impacts of the Chernobyl and Fukushima accidents doubles nuclear's km
2/GWh footprint, though it remains slightly less land-intensive than other energy sources. However, one more accident will put it on par with solar, and the long-term trend favors renewables.
