Japan has revised the timing of a planned release to the sea of treated but still radioactive wastewater at the Fukushima nuclear power plant to “around spring or summer," indicating a delay from the initial target of this spring, after factoring in the progress of a release tunnel and the need to gain public support.
The government and the plant operator, Tokyo Electric Power Company Holdings, announced in April 2021 a plan to begin releasing the treated wastewater into the sea starting in spring 2023. They say more than 1 million tons of water stored in about 1,000 tanks at the plant are hampering its decommissioning and risk leaking in the event of a major earthquake or tsunami.
