K-278 Komsomolets: Radioactive Submarine Leak Persists in Norwegian Sea

Beneath the Waves: A Cold War Relic Still Leaking Danger

More than three decades after its tragic sinking, a Soviet nuclear submarine is still quietly contaminating the deep sea. The K-278 Komsomolets, lost in the Norwegian Sea in 1989 after a catastrophic fire, continues to release radioactive material from its resting place 1,600 meters below the surface, according to a new study published in PNAS.

Key Takeaways

• The K-278 Komsomolets sank in 1989 following an onboard fire, carrying a nuclear reactor and two nuclear torpedoes.
• Recent research led by Justin Gwynn of Norway used a remotely operated vehicle to survey the wreck in 2019.
• Findings confirm ongoing leakage of radioactive material from the submarine's remains.
• The wreck lies at a depth of 1,600 meters in the Norwegian Sea, posing long-term environmental concerns.

This discovery underscores the enduring risks posed by Cold War-era nuclear assets lost at sea. While the immediate threat to human populations may be minimal, the slow release of radioactive material into the deep ocean raises questions about long-term ecological impact and the challenges of addressing underwater nuclear contamination.
