This is something I've been interested in for a while. The article barely scratches the surface, and I was somewhat annoyed to see Hanford and US disposal methods lumped in with what the Russians are doing, there really is NO comparison.
They mention the Russians tearing down reactors at Mayak... More popular for years was merely dumping the reactors in the ocean. They mention the comparatively well kept reactor holding at Vladivostok but don't mention the Lepse or the radiation count being read with the morning news in Murmansk.
And that doesn't even get into Mayak itself, probably the worst rad hazard on the planet and still an operational nuclear facility.
At first I thought the Bellona organization was akin to one of our American green weenie groups and there is a bit of that to them, but they're one of the few groups focusing on the terrible mess the Soviets left and the Russians keep shuffling from one side of the plate to the other.
