News Summary
A wasp nest containing radioactive material was discovered during routine operations at the Savannah River Site nuclear facility. Found near Tank 17, contamination levels exceeded regulatory limits by more than ten times. Although the radioactive wasps were exterminated and the nest treated as waste, the surrounding area showed no signs of contamination. This incident is categorized as legacy radioactive contamination, and officials confirmed that it did not disrupt operations. The discovery highlights ongoing environmental management challenges in nuclear facilities.
South Carolina – A wasp nest containing radioactive material was discovered at the Savannah River Site nuclear facility on July 3, 2025, during routine Radiological Control Operations. The nest was found near Tank 17, located adjacent to building 241-127F. Contamination levels of the nest registered at 100,000 dpm (disintegrations per minute), which exceeds regulatory contamination limits by more than ten times.
Upon discovery, the radioactive wasps were exterminated, and the nest was subsequently bagged and treated as radiological waste. Fortunately, officials confirmed that the surrounding ground and area displayed no indications of contamination, ensuring the ongoing safety of the facility.
The contamination detected in the wasp nest is categorized as “onsite legacy radioactive contamination,” which signifies that it is not linked to any recent failures in contamination control measures. However, the Department of Energy has not released further information regarding the specific cause of the wasps’ radioactive contamination.
Importantly, the discovery of the radioactive wasp nest did not disrupt any other operations or activities at the Savannah River Site. The site has been operational since the 1950s, primarily serving as a production facility for materials used in nuclear weapons, including tritium and plutonium-239 during the Cold War era.
In response to past environmental concerns, cleanup and remediation initiatives commenced in the 1980s, with the Savannah River Site designated as an Environmental Protection Agency (EPA) Superfund site due to contamination issues. Moreover, the National Nuclear Security Administration took over operational responsibilities at the Savannah River Site in 2024, indicating a continuing commitment to managing the facility’s safety and environmental integrity.
The delay in reporting the findings from July 3 was attributed to a necessary review process aimed at ensuring consistency with previous wildlife contamination reports. Such protocols are essential for maintaining transparency and public trust regarding environmental and safety practices at the site.
The Savannah River Site spans approximately 310 square miles and has a complex history intertwined with the United States’ nuclear weapons program. As environmental oversight progresses, the discovery of the radioactive wasp nest serves as a reminder of the intricate challenges faced in managing legacy contamination while ensuring operational safety in nuclear facilities.
Moving forward, ongoing monitoring and assessments will be critical in maintaining the health and safety of both personnel and the surrounding environment at the Savannah River Site. The discovery of radioactive contamination in wildlife underscores the importance of vigilance in environmental management efforts across nuclear facilities.
