NRC Commences Readiness Assessment of Terra Innovatum’s SOLO™ Construction Permit Application (CPA)

NRC establishes scope, schedule, and multidisciplinary review team for the first phase of the readiness assessment of Terra Innovatum’s planned SOLO™ Construction Permit Application

First phase will assess the Environmental Report and nine PSAR chapters covering key safety, reactor design, environmental, and licensing topics

Early NRC review of defined draft application materials is intended to help Terra Innovatum identify and address potential questions and information needs before formal CPA submission

NEW YORK, Aug. 19, 2026 (GLOBE NEWSWIRE) -- Terra Innovatum Global N.V. (“Terra Innovatum”, “Terra”, or the “Company”) (NASDAQ: NKLR), a developer of advanced micro-modular nuclear reactors, today announced that the U.S. Nuclear Regulatory Commission (“NRC”) has commenced the first phase of a limited-scope preapplication readiness assessment of defined portions of the Company’s planned Construction Permit Application (“CPA”) for its first-of-a-kind (“FOAK”) SOLO™ Micro-Modular Reactor.

Supporting a High-Quality Construction Permit Application

The readiness assessment is an important pre-submission step in Terra Innovatum’s licensing strategy, enabling NRC staff to review selected draft materials before the Company files its CPA and providing an opportunity to identify and address potential information needs, technical questions or policy matters early in the process.

The NRC issued its formal readiness assessment plan following Terra Innovatum’s July 20, 2026, request for a two-phase assessment of its planned CPA. The first phase commenced with an August 10, 2026, entrance meeting and is expected to continue for approximately six weeks.

First Phase Assessment Scope

During the first phase, NRC staff will assess the Company’s Environmental Report, prepared consistent with 10 CFR Part 51 and the National Environmental Policy Act (“NEPA”), and the following nine chapters of the Preliminary Safety Analysis Report (“PSAR”):

• Chapter 1: The Facility
• Chapter 2: Site Characteristics
• Chapter 4: Reactor Description (partial)
• Chapter 6: Engineered Safety Features
• Chapter 11: Radiation Protection and Waste Management
• Chapter 15: Financial Qualifications
• Chapter 16: Other License Considerations
• Chapter 17: Decommissioning and Possession-Only License Amendments
• Chapter 18: Highly Enriched to Low-Enriched Uranium Conversions
  

The NRC has established a multidisciplinary team from its advanced reactor licensing, reactor science, reactor engineering, environmental review and financial assessment organizations to conduct the first-phase assessment.

The assessment enables NRC staff to become familiar with selected draft application materials before formal submission and provides Terra Innovatum an opportunity to address potential information gaps and significant technical or policy matters in advance of its CPA.

Management Commentary

“The commencement of this readiness assessment is an important step in our disciplined strategy to advance SOLO™ through the rigorous U.S. regulatory process,” said Cesare Frepoli, Chief Operating Officer and Director of Licensing and Regulatory Affairs of Terra Innovatum. “The first phase covers key safety, environmental, reactor design, and licensing materials that represent a meaningful portion of our planned Construction Permit Application. Early, substantive engagement with the NRC staff provides an opportunity to identify and address potential questions before formal submission, supporting our objective of delivering a high-quality, review-ready CPA.”

Building on Ongoing NRC Engagement

The NRC’s August 5 readiness assessment plan builds on Terra Innovatum’s preapplication engagement with the agency since 2025, including public meetings, and submissions of white papers and topical reports across multiple technical and programmatic areas.

Following the first phase, NRC staff plans to hold an exit meeting with Terra Innovatum and issue a publicly available report summarizing its observations and feedback within 45 calendar days. The NRC also expects to issue a separate assessment plan for the application materials before the second phase begins.

The readiness assessment is a preapplication activity, separate from the NRC’s formal acceptance review process. It does not constitute NRC approval of the SOLO™ design or of any future CPA, or predetermine whether a future CPA will be accepted for docketing or how the NRC may evaluate it following docketing.
