TOKYO, Dec 24 (Reuters) - Tokyo Electric Power Co (9501.T) (TEPCO) said it restarted the 784-megawatt No.5 reactor at its Fukushima-Daiichi nuclear plant at 6:00 p.m. (0900 GMT) on Dec. 22 after a seven-week shutdown.
The No.5 reactor automatically stopped on Nov. 2 as its water level became unusually high while adjusting control rods. [ID:nTOE6A107L]
TEPCO found that a problem in a pump caused the stoppage, made repair work and changed maintenance procedures, the company said in a statement. (Reporting by Risa Maeda; Editing by Chris Gallagher)
