'Nuclear time bomb:' Downed K-27 submarine must be lifted out

Sunken nuclear sub in the Arctic

A Soviet K-27 submarine suffered a nuclear accident before being dumped at the bottom of the Kara Sea 30 years ago.

Russia may now have to lift the sub from dangerously shallow waters – before an “uncontrolled chain reaction” causes fatal damage.

“Radiation leakages will come sooner or later if we just leave the K-27 there. The sub has already been on the seafloor for 30 years, and it was rusty even before it was sunken. Leakages of radioactivity under water are nearly impossible to clean up,” Thomas Nilsen, a nuclear safety expert who has extensively mapped radioactive waste on the Arctic seabed, told RT.

Equipped with an experimental liquid-coolant nuclear engine, the K-27 was ill-fated from its launch in 1962. It made only three voyages, the last of which, in 1968, ended in tragedy. 

A short way from its base in the Barents Sea, its reactor malfunctioned, and the brave but badly-trained crew made a futile attempt to fix it.

Instead of solving the problem, they were exposed to fatal doses of radiation.

Nine seamen died, most of them in hospital in agony from radiation sickness several days after the accident.

The incident was kept secret by the Soviet government for decades, and the families of the victims received no compensation.

After repeated plans to redesign the sub, Soviet authorities decided it was easier to dispose of it, and towed the vessel to a remote test site in the Kara Sea, near the Arctic Ocean, in 1981.

Although international guidelines say decommissioned vessels should be buried at least 3,000 meters under the sea, the Soviet Navy scuttled it at around 75 meters.
