Westinghouse Electric Company has successfully finished the front-end engineering and experiment design (FEEED) phase for its eVinci microreactor prototype. This phase is part of preparations for testing at the Idaho National Laboratory (INL), scheduled as early as 2026. The eVinci microreactor is one of three innovative designs selected for evaluation at the world’s first nuclear microreactor test bed.
The FEEED phase is critical for developers like Westinghouse to plan and design the fabrication, construction, and potential testing of the reactor at the DOME test bed. The test bed is operated by the National Reactor Innovation Center (NRIC), a U.S. Department of Energy initiative.

What Are Nuclear Microreactors?
Nuclear is getting smaller and smaller. Nuclear microreactors are a prime example.
Several microreactor designs are being developed in the U.S. These small reactors are portable, fitting on a truck, and could address energy needs in remote locations, both commercial and residential, as well as military bases.
Microreactors are distinguished by 3 main features rather than their fuel or coolant, according to U.S. DOE’s Office of Nuclear Energy:
- Factory Fabrication: All components are pre-assembled in a factory and shipped to the site, reducing construction challenges and capital costs, and allowing quick deployment.
- Transportability: Their small size allows easy transportation via truck, ship, airplane, or train, making deployment versatile.
- Self-Adjustment: They are designed to automatically adjust operations with minimal operator involvement, using passive safety systems to prevent overheating or meltdowns.

Westinghouse’s completion of its prototype microreactor’s FEEED process moves the project a step closer to the testing and commercialization phase. The process involves creating a detailed schedule, budget, and design for the experiment, along with a preliminary safety report to ensure safe testing. This phase helps developers prepare for the eventual fabrication and installation of the reactor.
Westinghouse, along with Radiant and Ultra Safe Nuclear Corporation, was competitively selected to complete the FEEED process last year. Jon Ball, President of eVinci Technologies at Westinghouse, emphasized the significance of completing this phase:
“This marks a critical step in bringing the Westinghouse eVinci Microreactor to commercial operation. We are targeting deployment of multiple eVinci microreactors worldwide by the end of the decade. The strong partnership with NRIC, INL, and the Department of Energy is instrumental to our efforts.”
What is the eVinci Microreactor?
The eVinci microreactor is one of several designs funded by the U.S. Department of Energy’s Advanced Reactor Demonstration Program. This heat-pipe cooled reactor can generate 5 megawatts of electricity and is designed for sites as small as two acres. It can operate for 8+ years before needing to be refueled.
Unlike conventional reactors, the eVinci uses heat pipes to transfer heat out of its core, allowing for air cooling instead of water or pressurized gas. This makes it more efficient and suitable for various environments, especially remote areas where water is not easily accessible.
The microreactor has a wide range of applications, including:
- Powering remote communities
- Supporting mining operations
- Supplying energy to data centers
In 2023, Westinghouse announced an agreement to deploy an eVinci microreactor in Saskatchewan, Canada, showcasing its potential in cold, remote areas.
The Role of NRIC and the DOME Test Bed
Westinghouse will continue to work with NRIC to finalize the design and planning for the eVinci experiment. The company is also preparing for long-lead procurement items in anticipation of potential installation at the DOME test bed.
The NRIC, a program under the U.S. Department of Energy’s Office of Nuclear Energy, is dedicated to advancing the development of next-generation nuclear reactors. By bringing together industry and national labs, NRIC aims to help new reactor technologies move from the concept stage to demonstration and, eventually, commercialization.
The DOME test bed is a critical facility in this process. It provides a controlled environment where reactor developers can test fueled experiments with reduced risks. This collaboration between industry players like Westinghouse and national laboratories like INL accelerates the safe development of advanced reactor designs.
Radiant and Ultra Safe Nuclear Corporation are also expected to finish their FEEED processes by the end of the year. These companies are gearing up to test their own microreactor designs at DOME.
A Significant Step for Microreactor Innovation
Completing the FEEED phase is a major milestone in bringing microreactor technology closer to reality. Westinghouse is positioning itself as a leader in the next wave of nuclear technology.
The development of nuclear microreactors like the eVinci could have far-reaching impacts, providing a new, sustainable energy source for various industries and remote communities. It is a perfect example of how nuclear innovation is evolving to meet the energy demands of the 21st century.
With testing expected at the DOME test bed by 2026, and the continued support of the Department of Energy, these projects represent significant progress toward clean, reliable, and versatile nuclear power. As the world transitions to low-carbon energy sources, microreactors could play a critical role in the future of global energy.

The Strategic Case for Nature-Based Carbon Investments
Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.

EU carbon credit claims after 27 September 2026
EU carbon credit claims changed on 27 September 2026, the day the Directive (EU) 2024/825 began to apply across the European Union. The change is narrow. It changes how a company can talk about the credits it buys. A product can no longer be called neutral on the strength of compensation alone; however, every specific, evidenced statement about what a company measured, reduced, and funded stays fully available.
