Kansai Electric Power Co. said Friday it has started loading nuclear fuel into a reactor on the Sea of Japan following a court decision to lift an injunction against the move, paving the way for its restart in late January, which would be the country's third reactor to go online.

After the restart earlier this year of two reactors in southwestern Japan, while others remain offline in the aftermath of the 2011 Fukushima nuclear disaster, the No. 3 reactor at the utility's Takahama plant in Fukui Prefecture would be the first to run on uranium-plutonium mixed oxide, or MOX fuel, if it begins operations as scheduled.

The utility is scheduled to insert a total of 157 fuel rod assemblies by the next Tuesday, including 24 made from MOX fuel, according to Kepco.
