Work to restore electricity and crucial cooling systems at the crippled Fukushima No. 1 nuclear power plant resumed Tuesday, a day after workers were forced to evacuate when unidentified smoke spewed from reactors No. 2 and No. 3.
Firefighters sprayed a massive amount of water onto the spent nuclear fuel pool at the No. 3 reactor, while restarting similar efforts at the No. 4 reactor, according to Tokyo Electric Power Co.
Although white smoke — possibly steam — billowed continuously from the buildings housing the No. 2 and No. 3 reactors, Tepco said work could proceed as radiation levels didn't surge at the site.
