Tokyo Electric Power Co. has begun to put into operation a more efficient method of cooling the core of Fukushima Daiichi reactor 3. TEPCO announced yesterday that it had begun using the core spray system to cool the slumped fuel core from above. The company will gradually increase the flow rate in the core spray system as it reduces the flow rate of the feedwater system it had been using to cool the fuel.
The move is part of TEPCO’s recovery plan to reduce the temperature of reactors 1, 2 and 3 to below boiling.
