There is an unfolding drama happening at the Fukushima nuclear reactor number 4 which could possibly end in a doomsday scenario. This is no longer a Japanese problem.

Matt, this article from eurasiareview by Richard Rousseau has been going on for some time and yet does not grab the headlines that Fukushima has
Following the collapse of the Soviet system in December 1991 the Russian Federation inherited a little less than 200 nuclear powered submarines. At that time a significant number of these had been in use for about 30 years. During the first half of the 1990s the Kremlin decided to remove from active service all the older submarines, i.e. about 140 vessels, as part of downsizing the military budget. Over the following decade Russian leaders made great efforts to dismantle these rotting submarines and remove their nuclear fuel. However in the last 20 years the Russian Navy has been able to separate out and store the reactor compartments of only a few dozen submarines. At present all secured reactor compartments, including whole submarines, are stored and tied up in three traditional storage sites:
1) Andreeva Bay in the Zapadnaya Litsa fjord on the Kola Peninsula. Reportedly, the site hosts 21,000 spent fuel rods, equivalent to approximately 90 nuclear reactors, as well as thousands of tons radioactive liquid waste stored in decrepit stainless-steel containers filled to capacity since the 1990s. Three dozen of these containers are leaking radioactive material.
2) Nerpichya Port, on the Zapadnaya Litsa’s east coast., The site is home to 6 SSBNs (Ship Submersible Ballistic missile Nuclear [powered] vessels), better known as Typhoon ballistic missile submarines (of 25,000 tons), which still have on board torpedo tubes designed to handle and launch missiles. Each Typhoon has two pressurized water reactors of the OK650b type which use 20-45% enriched uranium-235 fuel. Each vessel’s weapon system is composed of 20 submarine-launched ballistic missiles (SLBM) which can carry 10 Multiple Independently targetable Reentry Vehicles (MIRV), each able to produce a yield of 21 kilotons.
3) Gremikha Base, east of the Kola Peninsula. The second largest onshore storage facility for the Russian Northern Fleet’s spent nuclear fuel, Gremikha contains around 800 spent-fuel assemblies. Reportedly, spent fuel from six liquid metal reactors (LMR), with 90% HEU are stored at this site, the largest for storing decommissioned submarines. The spent fuel comes entirely from the deactivated Alpha class submarines and, apparently, cannot be reprocessed with today’s technology. LMRs have to be treated more carefully because they used higher enrichment levels, probably weapons-grade uranium. The banks of the Gremikha base serve as a “parking lot” for several old-generation submarines now abandoned and in a dire state of repair:
4 November class vessels, for a total of 8 VM-1 PWR loaded with 21% HEU;
1 Hotel Class vessel with 2 VM-A PWRs loaded with 21% HEU;
8 Victor I\Victor II class vessels, for a total of 8 OK-300 VM-4 PWR with 21% HEU;
4 Victor III class vessels, for a total of 8 OK300 VM-4 PWR with 21% HEU.
All the mentioned cities, districts and military bases on the Kola Peninsula and Novaya Zemlya have radioactivity levels a thousand times higher than the normal dose a human being can tolerate. Even three to five kilometers away from these places levels of radiation are hundreds of times above the normal and represent extremely serious risks to human health and the environment. Over the years entire villages have been evacuated and their populations relocated in urban centers nearby. In the 1980s about 30,000 people lived in the Gremikha region; however, since the breakup of the Soviet Union the population has decreased to about 10,000, due to economic hardship and ongoing substantial reductions in the Russian military program [9]. Some cities have been closed to both foreigners and citizens of the Russian Federation. Access to these is restricted to the military or duly authorized technicians and workers.
