New Decommissioning Plan for Fukushima Daiichi: Priority on Internal Investigation of Unit 3 Before Fuel Debris Retrieval

The Nuclear Damage Compensation and Decommissioning Facilitation Corporation of Japan released on August 6 an outline of the 2026 edition of the "Decommissioning Strategic Plan," proposing technical approaches for the decommissioning of Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station. The plan highlights that, for the large-scale retrieval of melted fuel debris at Unit 3, expected to commence in or after fiscal year 2037, priority should currently be given to internal investigations of the reactor building to provide a more reliable basis for subsequent engineering plans. The plan states that the fuel debris retrieval method being studied by TEPCO still requires further improvement in certainty, with the key prerequisite being an understanding of the actual internal conditions of the reactor. Due to the high radiation levels of the water inside the unit following the accident...

U.S. NRC Approves Four SMR-300 Reactors at Oyster Creek Site in New Jersey

A retired nuclear power plant in New Jersey is getting a new lease on life with the construction of small modular reactors. The U.S. Nuclear Regulatory Commission (NRC) has approved the construction of four advanced small modular reactors (SMRs) at the site of the Oyster Creek nuclear power plant in New Jersey. The plant is currently in decommissioning, with more than half of the dismantling work completed. The Oyster Creek Generating Station, which began construction in December 1969 and operated for nearly 49 years until its closure in September 2018, was once the longest-operating commercial nuclear power plant in the United States. It produced over 192 terawatt-hours of carbon-free electricity in total. Supported by New Jersey's pro-nuclear legislation and stable local backing, Holtec plans to build...

US NRC Approves Oyster Creek Nuclear Power Plant License Termination Plan

The U.S. Nuclear Regulatory Commission (NRC) has approved the license termination plan for the Oyster Creek Generating Station. Located in Lacey Township, New Jersey, the plant is now more than halfway through its decommissioning and dismantlement work. With this approval, the project will proceed with the final phases of decommissioning and site restoration in accordance with the approved document. Before dismantlement of the Oyster Creek Generating Station in Lacey Township, New Jersey, Holtec International stated that the approval of the license termination plan involved coordinated efforts across multiple departments, including engineering, radiation protection, environmental services, work management, project controls, licensing, communications, and security, led by the regulatory affairs department. The Vice President of Oyster Creek Nuclear Power Plant...

Third fuel debris retrieval test at Fukushima Daiichi Unit 2 postponed due to robotic arm malfunction

The robot used by Tokyo Electric Power Company (TEPCO) for the third experimental fuel debris retrieval at Fukushima Daiichi Nuclear Power Station Unit 2 malfunctioned during an on-site operational test, forcing the cancellation of the plan originally scheduled to start after July 2026 if all went well. The company stated it will reassess the relevant procedures. The malfunction occurred in part of the large robotic arm equipment used to collect fuel debris. During an operational test in the reactor building of Unit 2, TEPCO found an abnormality in one of the motors driving the robotic arm, causing the brake to fail to release and the arm to be unable to extend. The company is currently studying the replacement of the faulty motor. The third experimental retrieval plan was to use a large robotic arm...

Japan's Ikata Nuclear Power Plant Unit 1 Decommissioning Plan to Enter Second Phase

The Environmental Safety Management Committee for the Ikata Nuclear Power Plant, established by the Ehime Prefectural Government, recently held a meeting to review the progress of the decommissioning plan for Unit 1 of the Ikata Nuclear Power Plant. The unit ceased operation in 2016 and is currently in the decommissioning implementation phase. Unit 1 of the Ikata Nuclear Power Plant is operated by Shikoku Electric Power Co. The company began decommissioning the unit in 2017, planning to carry out the work in four phases over a total period of approximately 40 years. Currently, the first phase has been largely completed, primarily involving the removal of nuclear fuel. Shikoku Electric Power Co. has applied to the Japanese central government to enter the second phase, which involves dismantling equipment around the reactor area, and has...

TEPCO says cooling interruption of spent fuel pool at Fukushima Daini Unit 1 due to human error

Tokyo Electric Power Company (TEPCO) announced on July 29 that the event in April 2026, where the spent fuel pool cooling system at Unit 1 of the Fukushima Daini Nuclear Power Plant was shut down for approximately 32 hours, was determined to be caused by human error. At the time of the incident, the plant was in the decommissioning phase. On April 5, a fault alarm was triggered by the cooling water circulation pump of Unit 1 at Fukushima Daini. After on-site personnel confirmed smoke from the equipment, the pump was stopped, resulting in an interruption of the spent fuel pool cooling system for about 32 hours. TEPCO previously stated that the cause was damage to the cable connecting the pump motor. According to TEPCO's latest explanation, the cable melting may be related to the installation method when the cable was replaced in 2012...
