Uranium detected in fuel debris from Fukushima Daiichi nuclear power plant
This is a photograph of the approximately 0.7 grams of fuel debris first removed in November from the Fukushima Daiichi nuclear power plant. It is rough and reddish-brown in color, with some black and shiny parts.
The Japan Atomic Energy Agency is carrying out the analysis at a facility in Oarai, Ibaraki Prefecture. The agency has indicated that it is typical fuel debris, with a large area of the surface containing uranium, and that the nuclear fuel and surrounding structures have melted and mixed together.
The radiation level is approximately 8 millisieverts per hour, and it is thought that the high temperature at the time of the accident caused the cesium to volatilize, resulting in the lower radiation level.
Tokyo Electric Power said that the next fuel debris removal operation will be carried out around next spring.
