Cracked Nuclear Tomb Leaks Radiation into Pacific
31 Mar
Summary
- A 1958 nuclear test created a crater now filled with radioactive debris.
- Cracks in the Runit Dome allow radioactive waste to leak into the lagoon.
- Rising sea levels and intensifying storms threaten the dome's integrity.
The Runit Dome, a concrete containment structure on Runit Island in the Marshall Islands, is showing signs of critical deterioration. Constructed in 1977 to seal a crater left by an 18-kiloton nuclear test in 1958, the dome now encases over 120,000 tons of radioactive debris from numerous past nuclear tests. Cracks have appeared in the concrete cap, allowing contaminated groundwater to penetrate the waste and leak into the surrounding lagoon with the rising and falling tides. This lagoon is used by a nearby human population, raising concerns about contamination.
Compounding the issue, rising sea levels and intensifying storms threaten the dome's structural integrity. Experts are worried that parts of the dome intended to remain above sea level may soon be submerged, increasing the risk of radioactive contaminants spreading further into the Pacific Ocean. Despite these concerns, the U.S. Department of Energy has stated the dome is not in imminent danger of collapse, attributing the cracks to aging concrete and noting the lagoon already holds significant radioactive material from past tests.
