NRC Begins Pre-Application Review of Terra Innovatum’s SOLO™ Nuclear Reactor Permit
Event summary
- NRC commenced a six-week readiness assessment of Terra Innovatum’s SOLO™ Construction Permit Application (CPA) on August 10, 2026.
- The first phase focuses on the Environmental Report and nine key chapters of the Preliminary Safety Analysis Report (PSAR).
- The assessment aims to identify and address potential information gaps before formal CPA submission.
- NRC will issue a publicly available report summarizing observations and feedback within 45 days of the assessment's conclusion.
The big picture
Terra Innovatum’s SOLO™ reactor is part of the broader trend toward advanced micro-modular nuclear reactors, which aim to provide scalable, affordable, and deployable nuclear power solutions. The NRC’s pre-application review is a critical step in validating the reactor’s safety and environmental compliance, which could set a precedent for other small modular reactor (SMR) developers seeking regulatory approval. The outcome of this assessment will influence investor confidence and the company’s ability to secure future deployments.
