Kansai Electric Power Co. has started work to load nuclear fuel into reactor 4 at its Oi nuclear plant in Fukui Prefecture.
The operation, which started Sunday, to place 193 uranium fuel assemblies in the reactor is to be completed by Wednesday. Kansai Electric aims to restart the reactor sometime in mid-May.
According to the company, the fuel-loading work started at 10 a.m. using a crane and containers. The operation will continue around the clock.
Reactors 3 and 4 at the Oi plant cleared Nuclear Regulation Authority screenings last year under strict new standards introduced after the March 2011 crisis at the Fukushima No. 1 nuclear plant.
Preparations have been underway to bring the Oi facility’s reactor 3, which was reactivated March 14, into commercial operations mode. Unless any problems are detected in an NRA inspection, the reactor will start commercial operations as early as Tuesday.
