US-based NuScale Power Corporation is deploying nuclear-specific AI tools to significantly speed up reactor development and cut information search times by up to 80%. Announced on 25 August 2026, this strategic alliance combines NuScale’s proprietary small modular reactor (SMR) expertise, Nuclearn’s AtomAssist AI platform, and Nuclear Promise X’s (NPX’s) implementation discipline to create highly specialised, traceable workflow tools for the nuclear industry.
As advanced reactor projects move from design into deployment, a key task is making timely, informed decisions across a growing volume of engineering information, licensing evidence, technical standards, and institutional knowledge. Rapid, traceable retrieval of information is essential to maintaining programme schedules.
The initiative is built on a specialised collaboration, with each partner filling a unique operational role. NuScale Power supplies proprietary advanced reactor engineering knowledge and licensing content. Nuclearn provides the AtomAssist platform featuring nuclear-specific language models. NPX integrates the technology directly into day-to-day engineering and project workflows.
Unlike general Large Language Models (LLMs) such as ChatGPT or search engines, this platform is specifically grounded to prevent hallucinations and ensure strict industry compliance. Engineers can trace generated answers back to the original controlled source documentation. The AI recognises specialised nuclear terminology, design data, and licensing regulations.
It is maintained by Nuclearn and NPX to prioritise data security and quality standards without cutting regulatory corners. An initial proof of concept successfully demonstrated that the tools drop information-retrieval time by up to 80%. By scaling this knowledge across technical teams, NuScale Power aims to accelerate its commercial deployment of 77 MWe NuScale Power Modules (NPMs).
The NMP is a pressurised water reactor with all the components for steam generation and heat exchange incorporated into a single 77 MWe unit, using standard light water reactor fuel. It is the first SMR design to receive approval from the US Nuclear Regulatory Commission (NRC). NuScale offers the units as VOYGR plants with a range of modules: a VOYGR-12 power plant comprising 12 modules is capable of generating 924 MWe.
“NuScale is building a transformative deployment model to integrate NuScale Power Modules (NPMs) into nuclear power plants in the near-term, which requires executing with speed, precision, and confidence,” said Dr José Reyes, Chief Technology Officer of NuScale Power. “This partnership with Nuclearn and NPX will equip our teams with the right purpose-built AI tools – grounded in our extensive proprietary knowledge – to work more efficiently while maintaining the highest safety and quality standards.”
Jerrold Vincent, CFO and Co-Founder of Nuclearn said AI is only as valuable as the knowledge it can be trusted to deliver. “In a highly regulated, safety-critical industry like nuclear, every answer must be grounded in controlled engineering and licensing information. Our platform understands the operational context, regulatory implications, and safety considerations behind every decision, and gives engineers rapid access to the knowledge they need. By combining nuclear-specific language models with NuScale’s trusted engineering and licensing content, we’re helping NuScale maintain complete traceability back to the original controlled source, enabling the team to move faster without reducing safety, quality, or regulatory compliances.”
Joshua Bell, Director of NPX US noted: “NuScale is taking a practical step the rest of the industry can learn from. NPX brings the nuclear project experience and implementation discipline needed to turn promising technology into practical tools that teams can use in their day-to-day work. This is not AI for AI’s sake. It is nuclear professionals working together to solve nuclear challenges using new technology, grounded in deep experience and the discipline our industry requires.”
