NRC Issues Final Environmental Impact Statement for Proposed Paducah Laser Enrichment Facility

The U.S. Nuclear Regulatory Commission has released a final environmental impact statement for the proposed Paducah Laser Enrichment Facility, known as the PLEF, located near Paducah, Kentucky. The document represents a significant regulatory milestone on the path toward constructing a new uranium enrichment plant in the United States.

According to announcements from Global Laser Enrichment and its majority owner Silex Systems, the final EIS supports the issuance of a licence authorising construction work to begin at the site. The completion of the EIS follows Global Laser Enrichment's submission of its construction licence application in July 2025.

Silex Systems, an Australian company that holds a 51 percent ownership stake in Global Laser Enrichment, developed the laser-based enrichment technology intended for use at the PLEF. The process, known as SILEX — Separation of Isotopes by Laser EXcitation — represents a distinct approach to uranium enrichment compared with the gaseous diffusion and gas centrifuge methods that have historically dominated commercial enrichment capacity.

The publication of a final EIS by the NRC is a procedural requirement under the National Environmental Policy Act and is a prerequisite for the agency to proceed with licensing decisions. The document evaluates the potential environmental consequences of constructing and operating the proposed facility. Its completion and the finding that it supports licence issuance moves the project closer to a formal construction authorisation.

For nuclear fuel supply-chain professionals, the PLEF represents a prospective new source of enriched uranium in the domestic U.S. market. If licensed and built, the facility would add enrichment capacity at a time when the industry has been focused on diversifying supply chains and reducing dependence on foreign enrichment services. The Paducah, Kentucky, site has a long history in the U.S. enrichment sector, having previously hosted a large gaseous diffusion plant operated by the Department of Energy.

No timeline for a final NRC licensing decision or a construction start date was provided in the available information. Further regulatory steps, including any required hearings or additional agency review, would typically follow the publication of a final EIS before a construction licence is formally granted.

South Korea approves life extensions for Kori units 3 and 4, restarts targeted for 2027

Regulatory approval granted

South Korea's Nuclear Safety and Security Commission has approved operating licence extensions for Kori units 3 and 4, located near Busan. The extensions permit unit 3 to operate until September 2034 and unit 4 until August 2035, adding approximately nine to ten years beyond their original 40-year design lives, which expired in September 2024 and August 2025 respectively.

Korea Hydro & Nuclear Power (KHNP) applied for the licence amendments in November 2023. The Korea Institute of Nuclear Safety, a regulatory agency of the commission, subsequently conducted a four-year safety review that included a radiation environmental impact assessment. Both units are 1,025 MWe Westinghouse pressurised water reactors that received their original operating licences in 1984 and 1985.

Independent assessments for each unit

Although the two reactors share the same design, the commission noted that their operating and maintenance histories differ. As a result, the actual condition of structures, systems, and equipment, as well as ageing deterioration and life assessment, were evaluated and reviewed separately for each unit. Commission Chairman Choi Won-ho stated that the regulator would thoroughly inspect the site to verify that agreed facility improvements are implemented in compliance with safety standards.

Restart timeline and facility improvements

KHNP has indicated it plans to restart both units during the first half of 2027. Neither unit is currently in operation. KHNP President Kim Hoe-cheon cited increasing power demand from advanced industries, including semiconductors and artificial intelligence, as well as carbon neutrality objectives, as factors underpinning the case for continued operation. The company stated that facility improvements and regular inspections will be carried out as follow-up procedures ahead of restart.

Site context: decommissioning and recent restart

Kori is a four-unit facility. Unit 1 was permanently shut down in June 2017 after 40 years of operation, becoming the first reactor in South Korea to enter decommissioning. KHNP submitted its dismantling application to the commission in May 2021, and decommissioning approval was granted in June of last year. Unit 2, whose original 40-year permit expired in April 2023, was restarted in April of this year following its own licence extension process.

South Korea currently operates 26 reactors, which together supply approximately one-third of the country's electricity generation.

Singapore signs first nuclear partnership agreements and launches three capability programmes

Partnership agreements signed at Singapore International Energy Week 2026

Singapore's Energy Market Authority (EMA) has signed its first partnership agreements under the Singapore Nuclear Manpower Development Programme, with AtkinsRéalis, China National Nuclear Corporation Overseas and X-energy. The signings took place at Singapore International Energy Week 2026 and mark a concrete step in the country's effort to develop the technical workforce needed to evaluate advanced nuclear energy technologies for potential power generation use.

Under the programme, public officials involved in energy development will gain on-the-job experience with international nuclear organisations from 2027 onwards. Placements will span project development, licensing, construction and regulatory frameworks, providing structured exposure across the nuclear project lifecycle.

Three programmes target government, industry and strategic advisory needs

Alongside the manpower development programme, the EMA has introduced two further initiatives. The second scheme targets Singapore-based businesses, offering funding for selected company personnel to participate in training programmes and industry attachments with international partners. The objective is to equip staff with competencies that support their organisations in advancing nuclear strategy and capability-building.

The third initiative, the Singapore Future Energy Fellowship, is designed to bring distinguished international energy leaders to Singapore to provide independent strategic advice on long-term energy policy, including low-carbon technologies such as nuclear. The first fellows are to be appointed in 2026, with a specific remit to support preparations for an IAEA Integrated Nuclear Infrastructure Review (INIR) Phase 1 Mission expected in 2027.

Consultant panel appointed to cover all 19 IAEA Milestones Approach areas

The EMA has also announced the appointment of a panel of consultants to support capability-building across the 19 areas defined by the IAEA Milestones Approach, the framework used by countries embarking on a nuclear energy programme. The panel's work will feed directly into Singapore's preparations for the forthcoming INIR Phase 1 Mission.

An INIR mission brings together international experts with direct experience in specialised nuclear infrastructure areas alongside IAEA staff. The process enables in-depth discussion of best practices in nuclear power infrastructure development, with recommendations provided in a report that the member state can use to update its national action plan.

EMA Chief Executive Puah Kok Keong stated that developing the capabilities to rigorously assess the safety and suitability of nuclear energy forms an important part of efforts to strengthen Singapore's energy security, and that the authority looks forward to working with the consultant panel ahead of the INIR Phase 1 Mission.
