The nuclear industry isn’t exactly known for moving fast, but NAAREA wants to change the game. The French startup has ambitious plans to roll out its compact nuclear reactor, and it just partnered with Phoenix Manufacture to make this vision a reality. What makes this particularly fascinating is the project's innovative use of 3D printing—a technique typically reserved for less regulated industries—in one where every component must meet stringent safety and regulatory standards. If they pull this off, it could set new precedents for how nuclear technology is constructed.
Major nuclear projects tend to drag on for years, even decades, due to strict safety regulations, high costs, and complex engineering requirements. For example, the Hinkley Point C project in the UK was approved back in 2016 but won’t be operational until at least 2027. Over the Atlantic, Georgia's Vogel reactors were meant to be completed by 2016, yet delays pushed their operational dates to 2023 and 2024, respectively, leading to over $16 billion exceeded costs. Finland's Olkiluoto 3 faced similar pitfalls, taking 17 years to reach full operational status. Meanwhile, the international fusion project ITER, which has roots going back to the 1980s, has been besieged by cost increases amounting to $5.2 billion, with full operation now projected for 2039. These lengthy delays showcase why nuclear innovations often lag compared to other energy sectors. But NAAREA, short for New Nuclear for the Acceleration of Energy and Resource Autonomy, is aiming to change this narrative by integrating 3D printing with nuclear technology.
NAAREA's XAMR microreactor is touted as the next-generation nuclear solution—small, modular, and capable of delivering cleaner energy without the extensive infrastructure traditional reactors require. Described as almost like having a nuclear plant in a box, this design aims to ease deployment where energy is needed without the long construction timelines and major investments needed by conventional plants.
Phoenix Manufacture, based in Niort, France, contributes its decades of experience producing precision-engineered components for high-stakes industries such as aerospace and defense to this collaboration. By injecting 3D printing technology, they hope to cut down production times and costs associated with nuclear components significantly. Traditional nuclear parts are not only pricey but can take months or even years to produce and require extreme precision. By using additive manufacturing (AM), NAAREA and Phoenix can potentially reduce production times from months to mere days or weeks. What’s more, 3D printing minimizes waste, allowing for more efficient production through careful, layer-by-layer construction.
The partnership will progress through five phases, beginning with material validation to confirm raw materials adhere to nuclear safety standards, before entering prototyping, and initial production stages by 2032. If all goes well, they aim to recycle and reprocess materials to minimize manufacturing waste throughout the process, along with scaling up production capacity as demand increases. Their systematic approach aims to prepare the XAMR reactor for wide-scale deployment efficiently, allowing the future micro-generator to be transported and assembled at NAAREA's dedicated facilities.
While NAAREA pushes forward with its microreactor development, Namibia's nuclear potential is getting attention as well. The African country, long known for being one of the globe’s top uranium producers, finds itself facing energy shortages, largely relying on hydropower and importing electricity. Namibia's President Nangolo Mbumba recently emphasized to Chinese officials the need to invest domestically to leverage local uranium resources for nuclear power generation—an intriguing pivot for the nation. “We want to add value to our uranium for the peaceful development of nuclear energy,” he stated after discussions about Chinese investments around tanks for their mining operations.
Global corporations, including Amazon and Google, are also stepping up to incorporate small modular reactors (SMRs) to meet rising energy demands. These mini-nuclear plants, generating under 300 megawatts, provide a more affordable avenue for both countries and companies compared to their larger counterparts, requiring significantly reduced capital investments. Nonetheless, local energy analyst David Jarret cautions there must be effective energy planning aligned with economic realities for Namibia’s nuclear aspirations to have lasting viability.
Jarret pointed out other African nations—like South Africa’s Koeberg Nuclear Power Station and Egypt’s El Dabaa Nuclear Power Station—showing greater development momentum, paralleling Namibia’s explorations. He noted the pressing need for regulatory support to drive nuclear energy developments, echoing sentiments shared by multiple stakeholders as some countries attempt to take leaps toward nuclear adoption.
Echoing safety fears associated with nuclear energy, the World Nuclear Association clarified the reality: commercial reactors cannot explode like nuclear bombs due to insufficient enrichment levels. They argue nuclear power remains one of the safest means of electricity generation and regularly displaces fossil fuels, reducing fatalities associated with traditional energy sources.
Back in Europe, UK Labour MPs have placed faith in nuclear energy as key to driving national growth. A recent letter highlighted the urgent need for financial backing for the planned Sizewell C nuclear plant, with 50 backbenchers urging Chancellor Rachel Reeves to explore this avenue immediately. Organized by Ipswich MP Jack Abbott, they warned, “the window is narrowing” for concrete actions toward this project. Abbott emphasized the Sizewell C project will significantly contribute to energy security and growth.
While the world contemplates the future of energy, the rising commitment to nuclear power across national borders speaks volumes about the pressing need for sustainable solutions across various sectors. The integration of innovative manufacturing techniques and resource management is paving paths toward realizing nuclear power's potential, contributing collectively to the global transition toward low-carbon energy sources.
