Japanese authorities are continuing frantic efforts to stabilise the reactors at the Fukushima nuclear plant.
Military helicopters have begun spraying water from the air onto the fuel rods after yesterday’s attempt failed due to high radiation levels.
There are fears that reactor number 3 may have released radioactive steam due to a reported damage to its containment vessel.
Indeed reactors 3 and 4 are causing the greatest concern – pressure is said to be rising again in number 3 while there are conflicting reports over the water levels in reactor number 4’s cooling pool.
Plant operator Tokyo Electric Power Co has said it is seeking to rig an electricity cable and restore the power supply to the plant’s cooling systems “as soon as possible”.
With radiation levels higher than normal, Japan’s Nuclear Safety Agency is continuing to play down the danger.
