FAQ: Terra Innovatum's SOLO Micro-Modular Reactor NRC Licensing Progress

What is the main development announced by Terra Innovatum?

Terra Innovatum has made significant progress in the U.S. Nuclear Regulatory Commission licensing process for its SOLO Micro-Modular Reactor, including the submission and acceptance of key technical documents like the Principal Design Criteria report.

Why is this licensing progress important for Terra Innovatum?

This progress represents a significant step forward in bringing the SOLO MMR to commercialization, demonstrating regulatory confidence and moving closer to real-world deployment of their innovative nuclear technology.

How is Terra Innovatum approaching the NRC licensing process?

The company is using a structured, stepwise approach under the non-power reactor licensing pathway outlined in NUREG-1537, submitting technical documents and topical reports in advance to allow early evaluation of key technical and safety elements.

What is the SOLO Micro-Modular Reactor and what are its key features?

The SOLO MMR is a 1 MWe, helium-cooled reactor designed to operate with commercially available low-enriched uranium fuel, featuring inherent safety characteristics, modular construction, simplified operations, and the ability to be deployed off-grid with a small land footprint.

When is the NRC expected to complete its review of the Principal Design Criteria?

The NRC indicated in a July 30, 2025 letter that it intends to complete the review process by the end of 2025 and issue a Safety Evaluation of the PDC report by April 2026.

Who are the key people involved in this development at Terra Innovatum?

Cesare Frepoli, Co-Founder, COO & Director of Regulatory Affairs, and Giordano Morichi, Partner, Chief Business Development Officer & Investor Relations, are the key executives mentioned in the announcement.

What makes the SOLO MMR suitable for global deployment?

The reactor was conceived with embedded Safeguards-by-Design, ensuring proliferation resistance and security considerations are integrated early, which facilitates regulatory acceptance across diverse markets from the United States to Europe and beyond.

How does the SOLO MMR differ from traditional nuclear systems?

Unlike traditional nuclear systems, SOLO can be deployed off-grid, supports flexible siting with a small land footprint, and offers simplified maintenance through factory fabrication and modular replacement.

What is the business structure behind Terra Innovatum’s development?

Terra Innovatum has signed a Business Combination Agreement with GSR III Acquisition Corp (Nasdaq:GSRT), a publicly traded special purpose acquisition company, as part of its intention to go public.
