The Fort Worth Press - Terra Innovatum SOLO(TM) Design Aligns with U.S. NRC's Recent Considerations of Streamlined Licensing Path for Proliferation-Resistant Micro-Modular Reactors

NEW YORK, NY AND AUSTIN, TX / ACCESS Newswire / July 23, 2025 / Terra Innovatum Srl ("Terra Innovatum," or the "Company"), a developer of micro-modular nuclear reactors, and GSR III Acquisition Corp. (NASDAQ:GSRT), a publicly traded special purpose acquisition company, today issued the following statement in support of the U.S. Nuclear Regulatory Commission's ("NRC") long-term vision for micro-modular reactor licensing, following the NRC's public meetings on July 17-18, 2025:

"We are encouraged by the NRC's recent public dialogue and their proposed rulemaking regarding future streamlined licensing for micro-modular and other low risk reactors. In particular, we support the NRC's introduction of limits on the type and quantity of proliferation materials - or 'Special Nuclear Materials' (SNM) such as uranium or plutonium - in its proposed fundamental entry criteria, which further validates and aligns with SOLO^TM's Safeguards by Design approach.

In Picture: A rendering of the SOLO™ reactor seamlessly integrated within a commercial real estate setting.

From the earliest stages of development in 2018, we conceived our micro-modular reactor with a clear global mission: to deliver a safe, low risk, and non-proliferant nuclear energy solution suitable for deployment in diverse environments around the world. Recognizing the unique challenges associated with the use of SNM, we emphasized proliferation resistance not as an afterthought, but as a core design principle.

Our reactor has been embedded with safeguards which aim to limit unauthorized access, diversion, or repurposing of fissile materials and align with guidance from the International Atomic Energy Agency and Department of Energy.

SOLO^TM's compact, sealed core design, limits SNM while incorporating a real-time core measurement to prevent the misuse of these materials. Additionally, our decision to use standard Low Enriched Uranium fuel supports international non-proliferation objectives while leveraging existing fuel infrastructure and licensing precedents.

We commend the NRC for its transparent, inclusive approach to rulemaking and look forward to participating in the formal comment process. Terra Innovatum remains committed to working with domestic and international stakeholders to advance the responsible deployment of micro-modular reactors - and to ensuring that designs like SOLO^TM continue to lead the way."
