That's the problem with simply giving away nuclear technology to any random nation. Even a 'veteran' of nuclear power like Russia has problems. The consequences of irresponsiblity can be beyond horror. Fortunately as with most "nuclear incidents" I've read, this incident was not related to the reactor core itself.
Well apparently the explosin took place in a smelting operation, which has nothing to do with the nuclear reactor. Possibly the smelter uses electric power coming from Unit 2.
The article is somewhat confusing, since smelting normally refers to extraction of metal from ore, such as a sulphide, but then the article refers to scrap metal recovery. I hope they don't mix in activated metals.
Pure FUD. Reactor walls have the integrity to withstand a blast from some smelter, even ones made in Russia.
Reminds me of when the press screamed about 'Japan's worst nuclear disaster' which killed four people. Of course they neglect to mention that it occured in a part of the plant that was completely unrelated to the reactor and is present in every fuel-based power plant under the sun.
