Evidence of Chain Reaction at Fukushima Unit 1.

Recent press reports have discussed the possibility that Fukushima Unit 1 may be having a nuclear chain reaction. Neutron bursts were detected 13 times, about a mile away from the reactor, as well as the presence of an “ethereal blue flash,” above the plant. Moreover, new data released by TEPCO indicates that even though Fukushima Unit 1 was shut down during the March 11 earthquake, it appears to have "gone critical" again.

In the video below, Arnie Gundersen, Chief Nuclear Engineer from Fairewinds Energy Associates, explains that the presence of neutrons inside a nuclear reactor means that a chain reaction is definitely occurring.  The discovery of isotope Chlorine-38, not present in nature, in Fukushima #1 reactor,  is more than likely, created by Chlorine-37, present in seawater, absorbing a neutron.  This chain reaction must be responsible for turning on a  portion of the nuclear core in reactor #1, without human intervention, considering it was shut down, at the same time as all of the other reactors, which do not show signs of the isotopes present in #1.
