A component's qualification lives in a thousand PDFs.
In nuclear, every component must prove origin, conformity and chain of custody. Today that proof is scattered across paper certificates, supplier emails and spreadsheets: preparing an audit means manually reassembling documentation that no one monitors in real time.
Component qualification
Every component has a digital dossier with requirements, evidence and an always-current qualification status.
Supplier documentation
Certificates and test reports enter in a structured way, verified against order requirements.
Chain of custody
From raw material to installed component, every lot is traceable with origin and transformations recorded.
Audit-ready
The compliance file is generated on demand, without preparation: the evidence is already complete and consistent.
Qualify
Define component and supplier requirements and open the qualification file.
Collect
Gather certificates and test reports, verified against requirements.
Track
Follow lots and transformations along the whole supply chain.
Prove
Generate the audit-ready compliance file at any moment.
LEDGER is a modular platform for nuclear supply-chain compliance: per-component qualification dossiers, structured ingestion of supplier documents and chain of custody from raw material to installed component, with a compliance file generable on demand.
Cloud
Managed platform on sovereign cloud with isolated supplier portals: each supplier uploads certificates and reports into its own perimeter, with defined data residency.
On-premise
Deployment in the operator or EPC data center, with secure connectors to qualified suppliers; compliance documentation stays under sovereign control.
Air-gapped
Isolated platform for sensitive programs: supplier documentation imported via verified media and compliance files exported offline for audit.
Immutable chain of custody
Origin and transformations of every lot are recorded immutably: traceability from raw material to installed component stays demonstrable for the plant's full life.
Evidence verification
Certificates and reports are verified against order requirements and ASME NQA-1 and RCC-M codes, with automatic flagging of missing or non-conforming documents.
Audit-readiness
The compliance file is generated on demand from live data, without preparation: the evidence is already complete, consistent and traceable for each component.
Access control and sovereignty
RBAC by supplier and order with AES-256 encryption; in on-prem and air-gapped modes supply-chain documentation never leaves the organization's perimeter, ISO 27001-aligned.
How do supplier certificates enter?
Suppliers upload certificates and test reports in a structured way through isolated portals; LEDGER verifies them automatically against order requirements.
How long does it take to prepare an audit?
No preparation: the compliance file is generated on demand from live data, already complete and consistent, cutting typical preparation time by 60%.
Does traceability cover material transformations?
Yes. The chain of custody records every lot from raw material to installed component, including melting, machining and treatments, with verifiable origin and transformations.
How does LEDGER connect to the site and archive?
Supplied components are linked to CADENCE for installation and certificates are archived in a certified way on VAULT, closing the loop from supply to as-built.
The mark encodes the mechanism, not the sector: la cupola di contenimento, il nucleo, le barre di controllo.
