THE PLATFORM
The secure GenAI platform built for nuclear operations.
One modular platform inside your own environment: intelligent access to decades of documents, secure integration of your data sources, and specialised agents that handle nuclear-specific tasks. Full AI capability, without your data ever leaving your infrastructure.
01 | Semantic Document Intelligence
Access decades of plant records in seconds — semantic search, document chat, summaries, and cross-document analysis. The platform understands nuclear context, technical terms, and abbreviations, and makes even scanned historical documents searchable.
02 | Secure Data & System Integration
Connect your existing sources — DMS, ERP, CRM and more — via APIs, MCP and connectors. Structured and unstructured data alike, always respecting your existing roles and permissions.
03 | Assistants & Nuclear-Specific Agents
Combine prompts, tools, data and systems into assistants — and run specialised agents built for nuclear tasks. From general research to domain-specific work, orchestrated across multi-step workflows.
04 | Your Environment, Your Rules
Run the platform entirely within your own environment — your cloud or fully on-premise — using the AI models best suited to each task. No data ever leaves your infrastructure, and it's never used to train models.
THE CHALLENGE
Nuclear operations put demands on AI that generic tools can't meet.
The knowledge exists. Getting to it reliably, under audit conditions and without leaving the plant's secure environment, is exactly where every off-the-shelf AI tool breaks down.
Complex Documentation
Safety-critical content changes constantly. Keeping it consistent and current across the plant is a permanent effort.
Massive Document Volume
Millions of files accumulate over a plant's lifetime. At that scale, finding the right information becomes slow and unreliable.
Continuous Compliance
Strict regulations demand continuous, complete documentation. Any gap can trigger findings.
Audit Pressure
Audits require long preparation and manual evidence collection — under considerable pressure.
Skilled-Staff Shortage
Experienced specialists are retiring, and their knowledge with them. New staff struggle to access what they need.
Strict Security Requirements
High nuclear security standards have kept modern GenAI out of reach. Off-the-shelf cloud AI is simply not an option.
DATA SOVEREIGNTY
Security & Compliance as an architectural principle.
Security & Infrastructure
- Regularly pentested by Binsec
- Use in critical infrastructure
- High Security Cloud-Concept
Access & Control
- Access Administration
- SSO over Identity Provider
- Customer Managed Key
Compliance & Sovereignty
- ISO27001 Dora GDPR
- Choice Azure Arithmetic Center
FLEXIBLE DEPLOYMENT
Your infrastructure. Our platform.
The platform runs wherever your security and regulatory requirements demand. In Azure, in another cloud, or fully on-premise. No lock-in, no compromise on security. Your data stays under your control, always.
Azure
Our recommended path. We deploy the platform natively in your own Azure environment — proven in production across all Swiss nuclear power plants.
Any Cloud
Prefer a different provider? The platform runs in your existing cloud environment just as securely — your infrastructure, your keys, your control.
On Premise & Air Gapped
For plants that stay off the cloud, the platform runs entirely within your own data center — nothing leaves your walls. We also help you select the right hardware to run it.
NUCLEAR USE CASES
Specialised agents for the work nuclear operations actually do.

YOUR END-TO-END PARTNER FOR AI IN NUCLEAR
Platform. Integration. Consulting & Change Management.
We don't just hand over a platform. GRAYOAK nuclear stays with you from the first assessment through integration and adoption, so your team works with real value, not just new technology.
01
GenAI Platform
A production-ready GenAI platform, proven in Swiss nuclear power plants, fully configured and security-compliant within your own environment.
02
Data Integration
Decades of documents and data, finally usable. Our DMS integration brings your existing knowledge into the platform, structured and unstructured alike.
03
Change Management
Technology only creates value when people use it. We bring your team along, with an adoption approach shaped by real experience in the nuclear sector.
04
Consulting
Nuclear domain expertise from day one. We develop individual use cases with demonstrable ROI, based on our experience in nuclear operations.
FROM INTRODUCTION TO ADDED VALUE
Live in about 10 weeks.
We handle the entire process: from deploying the platform to productive use and continuous development. The timeline below reflects a cloud deployment; on-premise setups take longer, as physical infrastructure has to be built.

Proof-points: Results after 12 months at Axpo.
550k Documents indexed, spanning 50+ years of operational history
1,800+ Messages per day in daily operations across all Swiss nuclear power plants
80% Active users — sustained adoption, not shelfware
80+ Assistants & data rooms for operations, compliance, and engineering
FROM INTRODUCTION TO ADDED VALUE
Proven in production across all Swiss nuclear power plants.
Axpo manages millions of documents spanning more than fifty years of operational history. The knowledge was there — but not reachable when it was needed. Traditional search fell short, experienced staff were retiring, and strict security rules ruled out off-the-shelf AI.
Over the past years, the platform has moved into daily operational use at Axpo — one of Europe’s leading energy providers. It runs inside Axpo’s own environment, and no data ever leaves it. Today it is in productive use across all Swiss nuclear power plants: document search in seconds instead of hours, with every answer traceable to its source.

FAQ
Your questions - our answers.
Is the platform available for any type of company?
No. The platform is built specifically for the nuclear and energy sector. We focus on the compliance, security, and operational realities of nuclear operators — down to specialised agents that address nuclear-specific use cases, not general-purpose use.
Does our data ever leave our own infrastructure?
Never. The platform runs entirely within your own environment — your cloud or fully on-premise. No data is sent to external servers or third-party AI providers, and it is never used to train AI models.
How long does implementation take?
In a cloud deployment, you can be live in about ten weeks. On-premise setups take longer, as physical infrastructure has to be built. Connecting your internal DMS systems is a subsequent step that adds several weeks.
Do we need our own IT team to operate it?
Not necessarily. GRAYOAK nuclear provides full integration support and ongoing technical assistance as part of the service — from deployment through day-to-day operation.
Is the platform compliant with nuclear regulatory requirements?
Yes. Compliance with nuclear-specific regulatory standards is a core design principle, not an add-on. We work directly with your regulatory and safety teams during implementation.
What happens to our existing documents and systems?
They stay where they are and become usable. The platform connects to your existing sources — DMS, ERP, CRM and more — and makes decades of documents searchable, without migrating or replacing anything. Your existing roles and permissions are respected throughout.
