Nuclear Princeton is an undergraduate-directed project that highlights the under-acknowledged impacts of nuclear science, technology, and engineering on Native lands, communities, and beyond. It locates the history of settler colonialism, environmental racism, and racial injustice in the past and contemporary technoscientific development and management of U.S. national security from the Manhattan Project onward. Princeton undergraduates interested in Native issues and culture play a key role in the project, exploring how Princeton scholars and the University—located on the unceded traditional territory of the Nanticoke Lenni-Lenape Tribal Nation—have made the world irreversibly nuclear.
