Terra Innovatum has announced an agreement with ATB Riva Calzoni to establish manufacturing processes, component costs, and logistics for its SOLO micro-modular nuclear reactor at ATB’s facility in Italy. This initiative launches early industrial production activities for the first-of-a-kind SOLO reactor and aims to support full-scale commercialization.
According to Terra Innovatum, the agreement covers phased collaboration steps to validate and refine component manufacturing, streamline assembly processes, optimize material handling at the factory level, and evaluate logistics for reactor delivery. ATB is providing advanced equipment, large-scale assembly space, and a team of specialized engineers dedicated to SOLO production.
SOLO is a compact, micro-modular nuclear reactor engineered for factory-based manufacturing and rapid on-site assembly. Terra Innovatum reports that SOLO uses commercial off-the-shelf components, supports both LEU+ and HALEU fuels, and is designed to minimize supply chain risks and costs. SOLO is expected to become available globally within the next three years.
For data center operators, SOLO is positioned as a behind-the-meter, CO2-free solution for power and heat. Terra Innovatum identifies additional target markets including mini-grids, industrial processes in sectors such as cement, oil and gas, and steel, as well as remote power needs and applications in water treatment and medical isotope production. The modular design enables scaling up to 1 GW or more of power with a minimal footprint.
Giordano Morichi, Chief Business Development Officer at Terra Innovatum, stated, “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.”
The collaboration with ATB is intended to standardize assembly lines for SOLO using repeatable manufacturing methods, enabling scalable and cost-effective nuclear reactor deployment.
