Tokyo Electric Power Company Holdings Inc. has estimated that it will take 44 years to decommission its Fukushima No. 2 nuclear plant.
Tepco presented the outline of decommissioning plans to the municipal assembly of Tomioka, one of the two host towns of the nuclear plant, on Wednesday.
The Fukushima No. 2 plant is located south of the No. 1 plant, which suffered a triple meltdown accident in the wake of the March 2011 massive earthquake and tsunami.
According to the outline, the decommissioning process for the No. 2 plant will have four stages, taking 10 years for the first stage, 12 years for the second stage and 11 years each for the third and fourth stages.
Tepco will survey radioactive contamination at the nuclear plant in the first stage, clear equipment around nuclear reactors in the second, remove the reactors in the third and demolish the reactor buildings in the fourth.
Meanwhile, the plant operator will transfer a total of 9,532 spent nuclear fuel units at the plant to a fuel reprocessing company by the end of the decommissioning process, and 544 unused fuel units to a processing firm by the start of the third stage.
Tepco will submit its finalized decommissioning plans for the Fukushima No. 2 plant to the Nuclear Regulation Authority after gaining approval from the municipal governments of Tomioka and the other host town, Naraha, as well as the Fukushima Prefectural Government.
