ABSTRACT
The radioactive mounds of America's nuclear programs exist today, with more to come. These disposal cells are tombs for the remains of uranium mill buildings and tailings, bulldozed into engineered enclosures constructed to limit contact with their surroundings for a thousand years. There are dozens of them—across the country, from Pennsylvania to Arizona—built within the past 25 years or so, mostly by the Department of Energy and maintained by their Legacy Management office.
