Nuclear chain reactions may be ongoing at Fukushima

re Nuclear Chain Reactions Still Occurring at Fukushima?

But you might not know that nuclear reactions may still be ongoing. Specifically, it is well-known by nuclear scientists that the ratio of iodine 131 to cesium 137 tells a lot about when nuclear reactions have stopped…

Today, Tetsuo Matsui at the University of Tokyo, says the limited data from Fukushima indicates that nuclear chain reactions must have reignited at Fuksuhima up to 12 days after the accident.

Matsui says the evidence comes from measurements of the ratio of cesium-137 and iodine-131 at several points around the facility and in the seawater nearby. He has calculated what the starting ratio must have been by assuming the reactors had been operating for between 7 and 12 months……

The data from the drain near reactor 2 and from the cooling pond at reactor 4, where spent fuel rods are stored, indicate that the reactions must have been burning much later….http://www.zerohedge.com/article/are-nuclear-chain-reactions-still-occurring-fukushima
