Japan : Heat exchanger for No1 reactor considered

Via NHK News :

" The Tokyo Electric Power Company is thinking about setting up a heat exchanger to hasten the full-scale recovery of the cooling system at the Number 1 reactor of the Fukushima Daiichi nuclear power plant.

TEPCO says 70 percent of the fuel is apparently damaged and 6 tons of water per hour is being injected into the reactor.

In order to cool it under more stable conditions, TEPCO wants the water level in the containment vessel to reach the height of the fuel rods

At present, the water level is estimated to be about 6 meters from the bottom of the containment vessel.

Two plans have been considered to cool the vessel, one uses sea water, the other air.

To avoid the risk of further damage from possible aftershocks TEPCO is favoring the water system."
