Discarded Russian submarines could cause a nuclear disaster in the Arctic  The Arctic could become a site of future turmoil, and not just because of the emerging geopolitical tensions and militarization in the region. Beyond concerns of a frozen conflict in the icy north, there is the additional fear that the Barents and Kara Seas could become the location of a slow-motion nuclear disaster. Until 1991 the Soviet Union used the seas as a junkyard where it would dispose of its nuclear waste.  According to the Bellona Foundation, citing the Norwegian Radiation Protection Authorities (NRPA), the Soviet Union dumped “19 ships containing radioactive waste; 14 nuclear reactors, including five that still contain spent nuclear fuel; 735 other pieces of radioactively contaminated heavy machinery; 17,000 containers of radioactive waste,” and three nuclear submarines in the seas. Disposing of nuclear waste and spent reactors at sea was actually a common practice around the world until the early 1970s. But the Soviet Union dumped a significant amount of material into bodies of water that were sometimes not that far from neighboring countries. Three scuttled nuclear submarines are the most dangerous of the disposals for the overall safety of the region — the K-27, the K-278, and the K-159, according to The Moscow Times. Of those, the K-27 is the one most likely to cause a Chernobyl-like event in which the casings of the reactors fail and dangerous amounts of radiation escape into the environment. The K-27 is particularly risky, the BBC reports, due to its unique design. The submarine, which was launched in 1962, was experimentally developed with two previously untested liquid-metal cooled reactors. Soon after deployment the submarine began emitting high levels of radiation, poisoning its crew.  In 1981, the Soviet Union sunk the submarine in the Kara Sea. But the sub was scuttled at a depth of only 99 feet (30 meters), significantly below international guidelines. More
