Alessandro Petruzzi, Co-Founder & CEO of Terra Innovatum, said, “Today’s announcement marks a key milestone in establishing Terra Innovatum’s outsourced manufacturing model. By leveraging ATB’s facilities, equipment, and proven expertise, we will produce our first SOLO reactor while completing the licensing process in the US for its deployment. Under this agreement, dedicated SOLO assembly lines will be created using standardized, repeatable processes—making reactor production predictable, scalable, and highly cost-efficient. This collaboration strengthens our partnership with ATB as we work together to deliver a safe, reliable, and sustainable source of power to the world.”

Giordano Morichi – Partner, Chief Business Development Officer & Investor Relations continued: “Partnering with ATB Riva Calzoni de-risks our commercialization by bridging the gap between investment and production, while mitigating the cost and schedule uncertainties that have long challenged nuclear projects. The compact, modular SOLO reactor is designed for lean, factory-based manufacturing and rapid on-site assembly—turning what once took years into months. With ATB’s proven industrial capabilities, we’re positioned to accelerate commercial deployment and deliver scalable, clean energy to the world.”

Francesco Squaratti, Managing Director, ATB Riva Calzoni added: “We see Terra Innovatum as a long-term strategic partner with whom we can establish a new global standard for microreactor manufacturing. With decades of experience building advanced components and systems for leading players in the nuclear industry worldwide, we are proud to bring our expertise to the next generation of clean energy. Together, through the SOLO program, we aim to usher in a new era of scalable, safe, and efficient microreactor solutions.”

The agreement outlines a phased collaboration that will:
(1) validate and refine key component manufacturing parameters to ensure optimized production for SOLO’s commercialization phase;
(2) develop, test, and streamline assembly processes for the first-of-a-kind (FOAK) unit, with a focus on scalable, repeatable manufacturing;
(3) design factory-level logistics for efficient material handling and just-in-time component availability during assembly; and
(4) evaluate transportation logistics and constraints associated with reactor delivery and deployment.
