TEPCO finds sign of fresh nuclear fission at Fukushima reactor | Kyodo News

Source: http://english.kyodonews.jp/news/2011/11/123753.html Tokyo Electric Power Co. said Wednesday there may be signs of fresh nuclear fission in the No. 2 reactor at its quake-damaged Fukushima Daiichi power plant and that it has begun injecting boric acid to control a possible nuclear reaction.
There has been no change in the temperature, pressure and radiation levels at the reactor, whose nuclear fuel is believed to have melted when the cooling system failed following the March 11 earthquake and tsunami, the utility known as TEPCO said.
Gas samples taken Tuesday from inside the reactor's containment vessel may contain radioactive xenon, a gas typically generated by nuclear fission, the company said.
