TOKYO, May 24 (Reuters) - Japan's top utility, Tokyo Electric Power Co (TEPCO) 9501.T, said on Monday it has delayed the planned restart of the 1,100-megawatt No.1 nuclear unit at its Kashiwazaki-Kariwa plant for an unplanned inspection and repairs.
The quake-hit reactor was slated to be restarted on May 22, but in tests before the restart the power firm found problems with a pump vent, forcing it to postpone the restart.
A TEPCO spokesman said that a new timetable for the restart of the unit had yet to be set, but that he anticipated the inspection and repairs to the unit would take about a week.
Last week, TEPCO got the go-ahead to restart the unit from three local authorities, after it had been forced shut by a major earthquake. [ID:nTOE64K03G] (Reporting by James Topham)
