In brief
Hyundai Engineering & Construction has signed a five‑year master service agreement with U.S. nuclear developer First American Nuclear Co. to provide engineering and construction support for FANCO’s EAGL‑1 small modular reactor. The EAGL‑1 is a 240‑MW SMR that uses a lead‑bismuth coolant instead of water and is moving toward regulatory approval with the U.S. Nuclear Regulatory Commission. The partnership aims to accelerate SMR commercialization and strengthen Hyundai’s position in the U.S. nuclear market.
In Seoul, Hyundai Engineering & Construction (E&C) Co. inked a five‑year master service agreement with First American Nuclear Co. (FANCO) of the United States on November 3, 2026, marking a significant step toward commercializing FANCO’s next‑generation small modular reactor, the EAGL‑1.
The accord expands a relationship that began under a framework agreement signed earlier in the year. Under the new terms, Hyundai E&C will provide a range of consulting services, including feasibility reviews, engineering and design consultations, and advice on construction methodologies for the EAGL‑1 project.
Engineered for the Future
The EAGL‑1 is designed to generate roughly 240 megawatts of electricity, a capacity that positions it as a viable substitute for traditional large‑scale nuclear plants while avoiding the extensive site footprint they require.
Unlike conventional reactors that rely on water‑based cooling, the EAGL‑1 uses a liquid metal mixture of lead and bismuth as its coolant. This choice shifts the engineering requirements for heat transfer and asset durability, prompting a new set of design and safety considerations that Hyundai E&C will help address.
Lead‑bismuth coolant systems can operate at higher temperatures while maintaining low pressure, which can translate into improved thermal efficiency. However, the unique properties of this coolant also necessitate specialized containment and handling protocols, a complexity that the partnership is set to mitigate through its engineering support.
Regulatory Engagement in the United States
FANCO is moving forward with a regulatory engagement plan submitted to the U.S. Nuclear Regulatory Commission (NRC). The NRC review process will determine whether the EAGL‑1 meets the safety and environmental standards required for commercial deployment in America.
The planning documents include a timetable for design validation, site assessments, and safety analyses that the consortium must satisfy before the reactor can receive an operating license. Hyundai’s engineering team will work closely with FANCO to ensure all required submissions reflect current NRC guidelines.
“Through this agreement with FANCO, we will drive the commercialization of the EAGL‑1 project and further strengthen our leading position in the U.S. SMR market,” a Hyundai E&C official said.
The statement underscores the strategic intent behind the partnership: to secure a foothold in the growing small modular reactor (SMR) segment of the U.S. nuclear market while advancing advanced design concepts.
Hyundai’s involvement extends beyond simple consulting. The company has stated it will offer expertise in reviewing construction feasibility and advising on innovative construction methods that can speed project timelines and reduce costs.
For Korean industry, the collaboration signals a broadened engagement with global nuclear initiatives. Korean engineers have been active in nuclear construction for decades, often focusing on large‑reactor projects. This project represents a pivot toward smaller, modular solutions that can be replicated and scaled more rapidly.
Moreover, by working with FANCO, Hyundai E&C will gain exposure to U.S. regulatory frameworks, which differ in several nuances from those in South Korea. That experience could prove invaluable as Korean nuclear operators look to expand overseas or adopt emerging technologies.
From an environmental perspective, SMRs offer a path to generate low‑carbon electricity. Though the source materials do not explicitly link the EAGL‑1 to greenhouse‑gas reductions, the broader consensus in the industry highlights SMRs’ potential to deliver clean, baseload power with fewer site commitments and potentially lower environmental footprints than conventional plants.
Adopting a lead‑bismuth coolant also sidesteps the reliance on water cooling towers, which can draw significant amounts of river or groundwater and generate evaporation loss. That factor speaks to a more efficient thermal management approach that could be advantageous for plants in water‑scarce regions.
The partnership’s five‑year timeline aligns with FANCO’s envisioned commercial rollout. Over the next half‑decade, both companies will jointly navigate engineering milestones, seek NRC approvals, and prepare for eventual construction of prototype or production units.
Thus, Hyundai E&C’s new master service agreement with FANCO signifies a strategic move to contribute to the spreading of small modular reactor technology and to strengthen cross‑border collaboration in nuclear engineering.
