Power has been extended ("connected") to the Fukushima complex, but it will be days before all functions are tested and repaired.

White smoke- possibly steam- billowed continuously from buildings housing No. 2 and No. 3 reactors, but Tepco said work could proceed if radiation levels didn't surge at the site.
Defense Minister Kitazawa said he believes the smoke rising from the No. 2 reactor was vapor given off by the water that had been sprayed, while the blackish smoke briefly detected Tuesday at No. 3 was likely rubble that caught fire.

Ventilation systems to filter radioactive materials from tha air are among key equipment that needed the electrical power.

Tepco hopes to restore power to data measuring systems and functions by Wednesday and by Thursday to the No. 3 and 4 reactors, according to a spokesman for the Nuclear and Industrial Safety Agency.
Tepco said work was ongoing to connect pipes to outside electrical supplies to pump seawater to circulation systems at No. 5 and 6, and the operation should be completed Wednesday.
