South Korea Promotes K-Decommissioning Nuclear Power Plant Decommissioning Technology Overseas

At the 2026 Nuclear Facility Decommissioning Business Forum held on the 18th at the Westin Chosun Seoul, Seo Beom-kyung (서범경), Director of the Clean Nuclear Facility Technology Development Department at the Korea Atomic Energy Research Institute (KAERI), stated that given the limited scale of the domestic nuclear facility decommissioning market, it is necessary to turn attention to overseas markets. Seo Beom-kyung said that the scale of South Korea's domestic decommissioning market is limited, so attention must be directed overseas. This requires the establishment of international standards, as well as decommissioning methods that reduce environmental burden and plans for subsequent site utilization. At the same time, emphasis must be placed on verifying K-Decommissioning technology in practical applications to ensure its performance and safety. Although technologies achieved at the R&D stage may...

South Korea's KNR Systems Completes Development of Robotic System for PHWR Decommissioning

KNR Systems announced on August 31 that it has completed the development of a platform system for remote cutting and dismantling of radioactive structures in Pressurized Heavy Water Reactors (PHWR), with final delivery scheduled to commence in September this year. The system originates from a government-commissioned PHWR decommissioning demonstration project. The project, valued at approximately 2.8 billion KRW, was awarded in January last year, with a development period of about seven months. Upon delivery, the equipment will be installed at the Heavy Water Reactor Decommissioning Technology Center of the Korea Research Institute of Decommissioning (KRID) in Gyeongju, for use in PHWR decommissioning demonstrations. Compared with light water reactors, PHWRs have more complex internal structures and typically higher levels of radioactive contamination, making dismantling operations more challenging.

Ikata Nuclear Power Station Unit 1 Decommissioning Phase 2 Plan Approved by Experts

An expert organization in Ehime Prefecture, Japan, regarding safety management at the Ikata Nuclear Power Station recently held a meeting to discuss the decommissioning plan for Unit 1 of the station. The report formed at the meeting deemed it appropriate for the unit to enter the second phase of decommissioning in fiscal year 2027. The meeting was convened by the Nuclear Safety Expert Subcommittee under the Ikata Nuclear Power Station Environmental Safety Management Committee. This committee is responsible for providing advice to the Governor of Ehime Prefecture on safety management at the Ikata Nuclear Power Station. At the meeting, eight academic experts reviewed the decommissioning plan for Unit 1. The decommissioning of Unit 1 at the Ikata Nuclear Power Station began in 2017 and is divided into four phases overall, planned to last approximately 40 years. Currently, the decommissioning work...

UK's Materials Detritiation Facility at Culham Resumes Operations to Support JET Fusion Decommissioning Materials Research

The UK Atomic Energy Authority recently announced that the Materials Detritiation Facility (MDF) at Culham has resumed operations following a 12-month engineering shutdown and upgrade. Experimental data produced by the facility has already been used to support research related to the removal of materials from the Joint European Torus (JET) device, providing a basis for waste management strategies under the JET Decommissioning and Repurposing (JDR) project. Over three years of plasma operations, deuterium-tritium (DT) experiments conducted at JET have left residual amounts of tritium in the tokamak's walls and internal components. This phenomenon is associated with tritium's tendency to enter materials under high-power fusion operating conditions. For JET decommissioning work, accurately determining the tritium...

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...

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...
