Study shows bulk of fuel still in crippled Fukushima No. 2 reactor

TOKYO, July 14, Kyodo

A study on the disaster-hit Fukushima Daiichi nuclear power plant has found that most of the melted fuel in the No. 2 reactor is still present in the reactor core area, sources close to the matter said recently.

According to the study that used a cosmic ray imaging system, around 200 tons of fuel and other melted substances is estimated to have accumulated at the bottom of the pressure vessel, the first time the current location of the fuel has been specified.

The finding is important for devising ways to remove the so-called fuel debris, the most challenging task in decommissioning the Nos. 1 to 3 reactors that suffered meltdowns in the nuclear crisis that began in March 2011.
