en.Wedoany.com Reported - On the morning of June 8, Tokyo Electric Power Company (TEPCO) transferred seven fuel assemblies from the spent fuel pool of Unit 2 at the Fukushima Daiichi Nuclear Power Plant to the on-site "common pool," marking the first transfer of remaining fuel from this unit's spent fuel pool. The Unit 2 spent fuel pool previously stored a total of 615 fuel assemblies, including 587 spent fuel assemblies and 28 unused fuel assemblies. Removal work began on June 2, starting with the removal of 28 unused fuel assemblies. On June 8, seven of these assemblies were transported to the building housing the common pool, with plans to gradually transfer all fuel to the common pool. Due to construction disruptions, the complete removal is expected to be completed by the end of fiscal year 2028.

Currently, the spent fuel pools of Units 1, 2, and 5 still contain 2,099 spent fuel assemblies, with a combined removal rate of 56.0% for new fuel from Units 1 to 6. Since 2025, TEPCO has been transporting new fuel from Unit 6 to a U.S. facility, and on May 28, announced plans to also transport new fuel from Unit 4 to the United States, aiming to complete fuel removal from all units by 2031.

Fuel debris removal also faces significant challenges. The total amount of debris collected from Unit 2 in two operations in November 2024 and April 2025 was only about 0.9 grams, while an estimated 880 tons of debris remains within the plant, with the amount removed representing only about one-billionth of the total. Following the initiation of fuel debris removal in 2024, the decommissioning of the Fukushima Daiichi Nuclear Power Plant has entered the final "third phase," with the Japanese government and TEPCO setting a target for decommissioning completion by 2051.
