Power lines connected at Japan nuke plant

TEPCO says power lines have been hooked up to all six reactor units.



Tokyo: The operator of Japan`s leaking nuclear plant says power lines have been hooked up to all six reactor units, though more work is needed before electricity can run through them.

The plant`s operator, Tokyo Electric Power Company, announced the hookup Tuesday but cautioned that workers must check pumps, motors and other equipment before the electricity is turned on.

Reconnecting the Fukushima Dai-ichi nuclear complex to the electrical grid is a significant step in getting control of the overheated reactors and storage pools for spent fuels. But it is likely to be days if not longer before the cooling systems can be powered up, since damaged equipment needs to be replaced and any volatile gas must be vented to avoid an explosion.

In another day of progress and setbacks, a pool holding spent nuclear fuel heated up to around the boiling point, a nuclear safety official said. With water bubbling away, there is a risk that more radioactive steam could spew out. "We cannot leave this alone and we must take care of it as quickly as possible," said the official, Hidehiko Nishiyama.

IAEA monitoring stations have detected radiation 1,600 times higher than normal levels — but in an area about 12 miles (20 kilometers) from the power station, the limit of the evacuation area declared by the government last week.

Radiation at that level, while not high for a single burst, could harm health if sustained. If projected to last three days, radiation at those levels would USauthorities would order an evacuation as a precaution.

The levels drop dramatically the further you go from the nuclear complex. In Tokyo, about 140 miles (220 kilometers) south of the plant, levels in recent days have been higher than normal for the city but still only a third of the global average for naturally occurring background radiation.
