The excellent French blog Gen4 has an entry about an accident at a nuclear plant in China in October 2011. This was reported in January 2012 by the Japanese Atomic Energy Agency, and was picked up by the Sankei Shimbun newspaper. The Daily Telegraph also picked up this story.
This is a military reactor outside of Beijing, an experimental fast breeder reactor cooled by liquid sodium. It also produces electricity as a by-product. It is Russian-built, and a similar reactor in Russia uses MOX fuel. MOX, of course, is enriched with plutonium. This reactor has been shut down since the accident. The main purpose of this reactor is probably to breed fuel for nuclear weapons.
The reason I suspect a meltdown versus an ordinary accident, is that I believe that there was a major release of radioactive iodine from late October 2011 – January 2012. A criticality occurred at Fukushima in late October of that year. Personally, I developed hyperthyroid symptoms, including a goiter, at this time. It seemed to contaminate the tap water, and many foods, not just American, but globally with many food products. The health message boards were lighting up with thyroid symptoms from the USA. And there was a spike of 5,000 excess deaths on the west coast of the US in November and December of last year.
It turns out it may have been not just Fukushima causing this global iodine cloud, but a reactor in China also.
The Chinese government never admitted this at that time. But this is not surprising. There was a nuclear meltdown at the Santa Susana nuclear power plant near Los Angeles in 1959, and they didn’t tell anyone. This was discovered by a group of students doing research 20 years later. How many meltdowns haven’t they told us about? They don’t give a damn.
Having said all this, I subjectively feel that the radioactive iodine level now is just as bad as it was a year ago when this was happening. I don’t know what is going on at the Fukushima plant.
