Tokyo Electric Power Co. will seek a ban on the operation of its quake-damaged nuclear plant lifted, paving the way for a test run when it completes repairs of one of the reactors next month.

"We will ask the local fire department to check our facility," President Masataka Shimizu told reporters today. Tepco will fix a turbine in early February, the final repair on the No. 7 reactor at its Kashiwazaki Kariwa nuclear plant, he said. Six other reactors are still being worked on.

The Kashiwazaki Fire Department imposed the ban after a magnitude 6.8 earthquake struck the plant on July 16, 2007, causing a fire and radiation leaks. Shimizu said he doesn't know when he can resume output at Kashiwazaki Kariwa, the world's biggest nuclear plant.

"We will ask the local authorities and government for approval after safety of all the equipment is ensured," Shimizu said.

Once the turbine is fixed, the utility will conduct function tests on the equipment and then restart the reactor for test run for the first time since the plant was shut.
