DOE Funds Molten Chloride Reactor Experiment, ASP Isotopes Plans Uranium Enrichment Plant

Molten Chloride Reactor Experiment Receives Funding

The U.S. Department of Energy (DOE) has approved cost-shared funding for the final stage of the Molten Chloride Reactor Experiment (MCRE) through its Advanced Reactor Demonstration Program. This funding supports work by Southern Company, Idaho National Laboratory, and CORE POWER to advance molten salt reactor technology.

The MCRE aims to be the first fast-spectrum molten chloride salt reactor experiment to achieve criticality. It is expected to provide data on fuel behavior, reactor operation, and performance, which will inform future reactor design, licensing, and commercial deployment. The project seeks to reduce technical risks and expand understanding of fast-spectrum molten salt systems, potentially accelerating innovation for various reactor developers.

Fast-spectrum molten salt reactors could extend beyond electricity generation to power industrial processes, produce medical isotopes, enable maritime propulsion, and extract value from used nuclear fuel. Future designs could utilize actinides from spent nuclear fuels to generate more energy and reduce nuclear waste volume and longevity. Some configurations may also support fuel breeding and medical isotope production. The MCRE itself will not use spent fuel, demonstrate a closed fuel cycle, or test a marine reactor.

ASP Isotopes and Necsa Plan Uranium Enrichment Facility

South Africa’s Necsa and a subsidiary of ASP Isotopes have signed a binding framework for a nuclear fuel venture. The venture, Quantum Leap Energy, would be approximately 80% owned by Quantum Leap Energy and 20% by Necsa. The proposed Pelindaba facility in South Africa would produce enriched uranium for advanced reactors, with TerraPower identified as a future buyer.

Supply agreements between TerraPower and ASP Isotopes are in place for the fuel the venture expects to produce. Quantum Leap Energy would manage operations and capital, while Necsa would provide site access, nuclear safeguards, and regulatory support. The project's cost, production capacity, and commissioning date have not been disclosed. ASP Isotopes noted that its enrichment technologies have not yet been applied to uranium-235, and the project requires further testing, financing, and regulatory approvals.

India's Peak Power Demand Exceeds 250 GW in September

Peak domestic power demand in India has remained above 250 GW for most of September, approaching summer demand levels. On October 5, the peak power demand reached 260 GW. This demand is attributed to cooling and irrigation requirements, exacerbated by below-normal monsoon rainfall.

India's power sector planner indicated a need for additional baseload capacity from conventional sources, such as thermal power plants, to meet the high demand, alongside renewable energy sources. Power consumption in September increased by approximately 11%.

Coal Stock Levels

Coal stocks at power plants, which had decreased due to heavy rains affecting production and supply in coal-bearing regions, are currently around 18 million tonnes. Specifically, domestic coal-based power plants held 17.9 million tonnes as of October 15, a decrease from 18.5 million tonnes on October 1. Plants utilizing imported coal have an inventory of 2.4 million tonnes.

Out of 190 coal-based power plants in the country, 82 are experiencing critical fuel levels, meaning their coal stock is less than a quarter of the target quantity required for uninterrupted electricity generation.

Regulatory Convergence Key to ASEAN SMR Deployment

Electricity demand in Southeast Asia is projected to increase significantly in the coming decades. Governments across ASEAN are committed to decarbonization pathways, despite current reliance on imported fossil fuels. Nuclear energy, particularly Small Modular Reactors (SMRs) in the 50–300 MWe range, could provide low-carbon generation to complement renewables.

Currently, no ASEAN member state operates a commercial nuclear plant. However, several countries are exploring nuclear options. Indonesia aims for multi-gigawatt capacity by 2040, Malaysia is considering nuclear power beyond 2035, and the Philippines targets 4.8 GWe by 2050, including assessing SMRs. Singapore has commissioned Mott MacDonald to study advanced nuclear energy technologies. Thailand is reintroducing SMRs into power planning, targeting 600 MWe, and Vietnam plans for two large nuclear power plants and an additional 8 GWe capacity by 2050.

Challenges and Proposed Solutions

Common constraints to nuclear deployment in ASEAN include fragmented regulation, uneven institutional capacity, financing uncertainty, limited specialist skills, and public acceptance challenges. Most countries may require close to a decade to establish the necessary regulatory frameworks and institutional confidence for initial operation. Regional cooperation is seen as crucial for accelerating this progress.

The current regulatory landscape, with each country maintaining its own codes, standards, and licensing processes, leads to multiple national reviews of the same SMR designs. This results in resource-intensive submission processes for vendors, extended timelines, increased costs, and reduced investor confidence. Without ASEAN-wide regulatory convergence, the benefits of SMR modularity and standardization may be undermined.

A proposed solution involves maximizing commonality through harmonized terminology, aligned evidence structures, and shared core safety expectations. Technology-centric licensing would involve a joint generic design evaluation by ASEAN regulators, with site-specific considerations remaining under national jurisdiction. Supplier and technology neutrality, assessed against transparent, evidence-based criteria, would broaden participation and support a resilient regional supply chain. Fuel strategies should also remain technology neutral, with coherent regional approaches for supply, transport, and safeguards.

Phased Roadmap for Convergence

A practical, phased approach to achieve regulatory convergence in ASEAN could include:

Regulatory convergence would streamline engineering deliverables, reduce rework, and enable the pooling of specialist expertise. This would improve the speed and robustness of regulatory decisions while preserving national sovereignty. For investors, clearer and predictable timelines would enhance bankability. For manufacturers and suppliers, common specifications and recognized quality systems would facilitate Southeast Asian participation in the global SMR supply chain.

  • Establishing governance and a shared regulatory language, potentially through an SMR convergence forum under the ASEAN Network of Regulatory Bodies on Atomic Energy (ASEANTOM).
  • Conducting joint technology evaluations against regional needs, potentially categorizing SMR technologies by intended purpose.
  • Aligning codes, standards, and supplier quality requirements, including an ASEAN vendor qualification framework with mutual recognition of supplier audits.
  • Addressing fuel assurance and lifecycle considerations, covering regional strategies for procurement, transport security, waste management, and decommissioning.
  • Clarifying finance and market frameworks by standardizing revenue models and risk allocation mechanisms.
  • Transposing common outputs into national frameworks and incorporating project data from early projects to reduce future costs and schedule risks.
