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...

U.S. nuclear energy company Holtec advances on two fronts this week: decommissioning aging nuclear plants and positioning small reactors in the southern U.S.

U.S. nuclear energy company Holtec recently announced two significant developments, reflecting the dual trend in the current nuclear power industry of retiring existing capacity while expanding new capacity. On one hand, the U.S. Nuclear Regulatory Commission approved the license termination plan for the Oyster Creek nuclear power plant, moving the decommissioning process of this veteran commercial nuclear facility in New Jersey, which began operations in 1969, past a key regulatory milestone. On the other hand, Holtec announced a partnership with Entergy and Hyundai Engineering & Construction to evaluate potential sites for deploying new reactors in the southern Gulf Coast region of the United States. The Oyster Creek plant ceased power generation in 2018 and was subsequently taken over by Holtec for decommissioning. The recently approved license termination plan...

Accelerating Nuclear Facility Decommissioning Can Drive Redevelopment of Legacy Nuclear Sites

Amentum recently proposed in a report on nuclear facility decommissioning financing and site regeneration that decommissioning should not be viewed solely as a cost item for reducing environmental and radiological risks. As a wave of nuclear reactors worldwide enters shutdown phases, shortening cleanup timelines, unlocking land value, and creating conditions for new industry attraction are becoming shared priorities for the nuclear industry and local economies. The report notes that traditional decommissioning models often leave facilities in long-term surveillance and maintenance status, which, while deferring some expenditures, also delays land reuse, industry attraction, and community benefits. In contrast, accelerated decommissioning can eliminate environmental liabilities earlier, reduce...

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...
