Workers Pulled Temporarily At Fukushima As Smoke Rises

Operators evacuated workers from Japan's tsunami-damaged nuclear plant Monday after gray smoke rose from one of its reactor units, the latest of persistent troubles in stabilizing the radiation-leaking complex.

The evacuation brought to a standstill some of the work on restoring the plant's electrical lines and restarting the water pumping systems needed to keep nuclear fuel from overheating and releasing even greater amounts of radiation.

Tokyo Electric Power Co. spokesman Hiroshi Aizawa said the evacuation was prompted by smoke rising from the area of the spent fuel storage pool at the plant's Unit 3 reactor building. However, nuclear safety agency official Hidehiko Nishiyama later told reporters in Tokyo he didn't think the smoke was linked to the fuel pool.

"We are checking the cause of the smoke," nuclear safety agency official Hidehiko Nishiyama said in Tokyo.

There had been no explosion, and no immediate spike in radiation at the plant, Nishiyama said.

Japanese officials had reported some progress over the weekend in their battle to bring the Fukushima Dai-ichi plant under control after it was damaged during the massive March 11 earthquake and tsunami that devastated northeast Japan and likely left more than 18,400 people dead. But there also were hitches, including an unexpected surge in pressure in the reactor core at the troubled Unit 3.

And the nuclear crisis was far from over, with the discovery of more radiation-tainted vegetables and tap water adding to public fears about contaminated food and drink.
