The U.S. is reigniting its nuclear ambitions—and it just took a big leap forward. The Department of Energy (DOE) recently conditionally selected Oak Ridge, Tennessee-based Standard Nuclear as the first company to join its newly launched nuclear fuel line pilot program, part of the Trump administration’s broader strategy to rebuild America’s nuclear energy leadership.
This initiative, announced in July 2025, directly supports President Trump’s Executive Order on Deploying Advanced Nuclear Reactors for National Security. It aims to end the country’s reliance on foreign enriched uranium and critical nuclear materials by building a secure, domestic fuel supply chain—one built on innovation, speed, and private sector partnership.
U.S. Secretary of Energy Chris Wright said,
“With President Trump’s leadership, the Energy Department is moving at a rapid pace to unleash innovation and maintain American leadership in nuclear energy development,”. “Advanced nuclear reactors will be a game-changer for the United States, and with that comes the need to fabricate the fuel for these reactors. The Department of Energy is partnering with private sector innovation with DOE expertise to assure stronger U.S. nuclear supply lines.”
Powering the Future: Advanced Reactors Need Advanced Fuel
Advanced nuclear reactors are central to America’s clean energy and national security goals. But to power them, the country needs more than just designs; it needs the right fuel.
That’s where Standard Nuclear steps in. It’s now the first company conditionally approved under DOE’s fuel pilot program, giving it access to fast-track processes and support. The company will focus on producing TRISO (TRi-structural ISOtropic) fuel, a next-generation nuclear fuel known for its unmatched safety, durability, and performance.
Standard Nuclear will lead the construction, operation, and eventual decommissioning of the fuel fabrication facility. Meanwhile, reactor developers will source nuclear material feedstock potentially through the DOE’s high-assay low-enriched uranium (HALEU) program, for conversion into TRISO fuel.
TRISO Fuel: The Toughest Fuel on Earth
TRISO fuel is engineered for extreme performance. Each tiny fuel kernel—about the width of a human hair—is coated in multiple layers of ceramic and carbon. These layers act like a built-in containment system, ensuring that even under high temperatures (up to 1,600°C), the fuel doesn’t melt or release harmful materials.
TRISO Particles
Key highlights of TRISO fuel:
- Microscale safety: Each particle is a self-contained barrier, lowering the risk of large-scale radioactive release.
- High performance: TRISO can operate at much higher temperatures than traditional fuels, increasing thermal efficiency.
- Unmatched resilience: The fuel resists mechanical failure, corrosion, oxidation, and neutron damage.
This design makes TRISO a perfect fit for advanced reactors, especially those planned outside traditional nuclear sites—including defense, microreactors, and space power systems. Also, compared to traditional nuclear fuel rods, TRISO’s structure is safer, more resilient, and ideal for new reactor types under development in the U.S.
Dr. Kurt Terrani, PhD, Chief Executive Officer of Standard Nuclear, said,
“Most of the long-anticipated wave of advanced reactors finally arriving to the market are harnessing the unique, inherent advantages of TRISO fuel—benefits that have been validated through decades of DOE and NRC investment and scientific rigor. These reactors can’t run without fuel, and we’re here to ensure there are no uncertainties in that supply. We’re not just delivering TRISO fuel at scale—we’re doing it at a cost that enables a robust, competitive, and sustainable advanced reactor industry.”
Standard Nuclear’s Reactor-Agnostic Advantage
What makes Standard Nuclear stand out is its reactor-agnostic model. Unlike traditional nuclear companies, it doesn’t develop its own reactors. Instead, it focuses exclusively on nuclear fuel, allowing it to serve a wide range of reactor designs.
Founded in 2024 at the historic K-25 Nuclear Site in Oak Ridge, the company operates a fully permitted, 19,000-square-foot radiological facility on a 36.8-acre campus. Its team brings over 150 years of combined experience from the U.S. Department of Energy National Labs.
The company booked more than $5 million in contracts in early 2025 and is projecting over $100 million in non-binding fuel sales for 2027. Clients include private firms like Radiant Industries, Antares, Nano Nuclear Energy, and Jimmy Energy, as well as U.S. government agencies such as the DOE and the Department of Defense.
Teaming Up with SHINE Technologies for Nuclear Fuel Recycling
Standard Nuclear recently announced a strategic partnership with SHINE Technologies to support nuclear fuel recycling and close the fuel supply loop. SHINE will supply recycled uranium and plutonium from its planned used nuclear fuel recycling plants to Standard Nuclear. The materials will be used in TRISO fuel production and to create heat-generating isotopes like strontium-90 and americium-241 for compact power systems.
This partnership will enable the development of a circular nuclear economy. By recycling materials once considered waste, both companies aim to make nuclear fuel production more sustainable and secure.
From Bankruptcy to Breakthrough
Standard Nuclear emerged by acquiring the assets and fuel technology of the bankrupt Ultra Safe Nuclear Corporation (USNC) for $28 million. The acquisition gave the company a head start with proven technology and permitted infrastructure.
To support its rapid expansion, Standard Nuclear raised $42 million in funding led by Decisive Point, with participation from Andreessen Horowitz and Washington Harbour Partners. The funding will be used to expand production capacity and meet growing demand from the advanced nuclear sector.
Standard Nuclear is Backing the Trump Nuclear Renaissance
Standard Nuclear’s selection is part of a broader plan under the Trump administration to reignite nuclear innovation. On May 23, 2025, President Trump issued four executive orders aimed at streamlining reactor testing and accelerating the deployment of advanced reactors for national security purposes.
Executive Order 14301 specifically directed the DOE to reform its national lab processes and launch a pilot program for testing next-gen reactor designs. The goal is to reach criticality for at least three advanced reactors outside of national labs by July 4, 2026.
This announcement coincides with other moves such as funding for the Palisades restart, development of microreactor test beds, and expanded HALEU production. Together, these initiatives represent a coordinated national effort to reclaim nuclear leadership.
The Bigger Picture: Why This Matters
Standard Nuclear’s rise signals a major milestone for America’s nuclear sector. Its work supports national energy security by reducing reliance on foreign fuel supplies and boosting domestic capabilities.
It also directly enables the rollout of advanced reactors, which promise cleaner, safer, and more resilient energy systems. These reactors, many of which are smaller and modular, require specialized fuels like TRISO that Standard Nuclear is uniquely positioned to provide.
From grid-scale power and remote installations to military bases and even future space missions, the role of advanced nuclear energy is expanding. Standard Nuclear is helping to ensure the U.S. has the fuel infrastructure to meet that demand.

The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon. Schedule a consultation.
Net zero is often described as a balancing act: cut what you can, account for the rest, and reach zero on the ledger. That framing is useful, but it leaves something out. It treats every tonne of carbon as interchangeable and every route to zero as equally sound, while the science tells a more specific story.
Malawi has lost a striking share of its forests over the past three decades. Woodlands that once covered well over a third of the country now cover less than a quarter, and the pressure on what remains is increasing. Behind those figures sit two practical questions: what is driving the loss, and what reverses it?
