Work to connect power cables to the No. 3 and No. 4 reactors was halted Monday at the crisis-hit Fukushima Daiichi nuclear power plant, after smoke rose from the buildings housing the No. 2 and No. 3 reactors, the plant operator said.
Tokyo Electric Power Co. said it will resume the operation on Tuesday after observing the situation at the site.
TEPCO said it had briefly evacuated its workers after grayish and blackish smoke was spotted at the southeast of the No. 3 reactor building around 3:55 p.m. above a pool storing spent nuclear fuel, though a blast was not heard.
The smoke stopped after 6 p.m., but TEPCO subsequently found that white smoke was rising through a crack in the roof of the building that houses the No. 2 reactor at around 6:20 p.m. The utility said later the smoke is believed to be steam, not from the reactor's fuel pool.
