Terra Innovatum Positioned for Accelerated, Scalable Deployment as NRC Advances Draft Part 57 Microreactor Rulemaking

NEW YORK, April 27, 2026 (GLOBE NEWSWIRE) — Terra Innovatum Global N.V. (NASDAQ: NKLR) (“Terra” or the “Company”), developer of the SOLO™ Micro-Modular Reactor, today highlighted the significance of the U.S. Nuclear Regulatory Commission’s (“NRC”) advancement of its draft Part 57 microreactor rulemaking framework for microreactors. The draft rule signals a potential structural evolution in U.S. nuclear regulation, introducing a framework intended to support fleet-scale deployment of standardized microreactor systems, rather than traditional one-off project licensing.

The proposed approach incorporates risk-informed, performance-based principles and recognizes the role of transportable, modular systems, with the potential to enable more efficient regulatory engagement and reduce reliance on prescriptive design requirements, thereby supporting more efficient regulatory pathways for qualifying microreactor systems. Terra Innovatum believes this direction closely reflects the design philosophy underpinning the SOLO™ platform and positions the Company particularly well to benefit from the evolving regulatory framework.

The proposed structure of Part 57 incorporates several elements that align directly with Terra Innovatum’s SOLO™ architecture, including:

• Recognition of factory fabrication, enabling off-site manufacturing, assembly, and testing prior to deployment
• Standardized design approval pathways, supporting repeatable deployment of a single approved reactor design across multiple sites
• Risk-informed, performance-based licensing approaches, tailoring requirements to smaller reactor systems with inherent safety characteristics and reduced potential off-site impact at the unit level
• Support for transportable, modular deployment, reflecting the role of microreactors as flexible, distributed energy assets

We believe this approach is particularly well suited to microreactor designs that prioritize inherent safety, simplicity, modularity, and repeatable, factory-based deployment, characteristics that are central to the SOLO™ platform. These attributes are expected to become increasingly important under the Part 57 framework, particularly as key segments of the industry move toward standardized, multi-unit deployment models.

Taken together, the draft framework outlines a regulatory model intended to support fleet-scale deployment rather than one-off construction. This distinction is expected to become increasingly important in meeting emerging power demand across data centers, industrial infrastructure, and energy security applications, while enhancing visibility into potential commercialization pathways.

This distributed, modular approach enables aggregate power output to scale while maintaining the safety profile characteristics of smaller individual units.

“SOLO™ was designed for this moment,” said Alessandro Petruzzi, Chief Executive Officer of Terra Innovatum. “We built SOLO™ as a safe-by-physics, factory-manufactured, modular system composed of smaller units with limited individual core inventories. This architecture supports scalable deployment while maintaining strong inherent safety characteristics at the unit level. The NRC’s draft Part 57 framework reflects that direction and supports a more efficient path toward commercialization.”

“The draft Part 57 framework represents an important step toward aligning regulatory processes with the realities of factory-based manufacturing and fleet deployment,” said Cesare Frepoli, Co-Founder, Chief Operating Officer and Director of Licensing and Regulatory Affairs at Terra Innovatum. “While the rulemaking is still in development, it signals a clear intent to support more flexible and efficient licensing pathways for qualifying microreactor systems. Terra Innovatum has been engaging early with the NRC under the existing framework, and we believe that positions SOLO™ well as the regulatory pathway continues to evolve.”

The NRC’s advancement of Part 57 comes at a time of accelerating demand for high-reliability, carbon-free power, driven by next-generation data infrastructure, industrial electrification, and energy security priorities. The draft rulemaking signals a regulatory environment evolving to support more standardized manufacturing, improved licensing efficiency, and scalable deployment models.

Terra Innovatum has already progressed key elements of its licensing strategy under the existing NRC framework, including the docketing of SOLO™ Topical Reports. The Company believes its early regulatory engagement, combined with a design philosophy aligned with the draft Part 57 structure, positions it to move efficiently within this emerging licensing framework as it is further developed and formalized.

The Company continues to advance toward its Construction Permit Application (CPA) readiness review while progressing industrialization and supply chain execution to support first-of-a-kind (FOAK) deployment and subsequent scaled, nth-of-a-kind (NOAK) commercialization.
