NRC advances Part 57 framework enabling standardized deployment of Terra Innovatum’s SOLO™
The U.S. Nuclear Regulatory Commission advanced its draft Part 57 microreactor rulemaking framework, introducing risk-informed, performance-based licensing and standardized approvals for factory-built, transportable microreactors. Terra Innovatum’s SOLO™ microreactor, with modular units and limited core inventories, aligns with Part 57 principles, positioning the company for repeatable fleet-scale deployment and faster commercialization.
1. NRC advances draft Part 57 microreactor rulemaking
The NRC published a draft Part 57 framework to support fleet-scale deployment of microreactors, introducing risk-informed, performance-based licensing, standardized design approvals and recognition of transportable, factory-built systems to streamline regulatory engagement.
2. SOLO™ design alignment
Terra Innovatum’s SOLO™ microreactor features modular units with limited individual core inventories, off-site manufacturing and repeatable design approval pathways that directly match the proposed Part 57 structure.
3. Regulatory engagement and readiness
Terra Innovatum has docketed SOLO™ topical reports under the existing framework and is advancing toward a Construction Permit Application readiness review, leveraging early engagement to adapt to evolving rules.
4. Commercial deployment outlook
The Part 57 framework’s emphasis on standardized, multi-unit deployment positions SOLO™ for scalable, CO2-free power in data centers, industrial infrastructure and energy security applications, accelerating commercialization.
