Routine radiation checks at the Savannah River Site this month uncovered a wasp nest measuring 10 times federal limits, prompting cleanup and fresh scrutiny of the former bomb-making complex.
Jeffrey Collins reports for The Associated Press.
In short:
- Inspectors discovered the empty nest on July 3 on a post beside 43 underground tanks storing 34 million gallons of liquid nuclear waste.
- Its radiation level was ten times the federal limit, yet officials say the spike stems from longstanding onsite contamination rather than a new leak.
- The nonprofit Savannah River Site Watch argues the brief report omits the origin of the hot material, the wasp species involved and whether other nests are forming.

“I’m as mad as a hornet that SRS didn’t explain where the radioactive waste came from or if there is some kind of leak from the waste tanks that the public should be aware of."

Why this matters:
Radioactive wildlife nests point to the persistence of long-lived contaminants that dust, wind, and rain can move beyond concrete shields built decades ago. Insects forage widely and incorporate soil or plant fibers into their nests, effectively sampling their environment and, if the material is hot, concentrating it where children or animals might one day encounter it. The Savannah River Site sits along the Savannah River, a drinking-water source for communities downstream and refuge for endangered species. Even low-level releases can work their way up food chains, complicating cleanup timelines and budgets. The episode spotlights the need for vigilant monitoring as Cold War facilities age.
