Tokyo Electric Power Company Holdings Inc. on Friday projected that the storage tanks for the treated contaminated water at its Fukushima No. 1 nuclear plant would reach full capacity in three years despite plans to expand storage space, complicating the government's efforts to tackle the build-up.

Despite the dwindling storage space, a government committee tasked with deciding what to do with the treated water build-up said at a meeting it would consider sticking with holding the water at the facility for the foreseeable future due to strong objections from residents to discharging it into the sea.

During the meeting, Tepco projected that storage would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate.
