Stand up a nuclear material accounting network covering the complete fuel lifecycle from fabrication to disposal, with IAEA-accessible safeguards records and a continuously verifiable material balance. An inspection completes in days from on-chain records, with full chain of custody from fabrication to spent fuel storage.
Replace fragmented material records with a continuously verifiable, inspector-accessible chain of custody.
01.
The Traceability Ledger records every quantity of nuclear material at each facility, so the material balance is continuously verifiable rather than reconciled after months.
02.
Each transfer from enrichment to fabrication to reactor to storage is co-signed and sealed, making a missing declaration structurally impossible to hide.
03.
The Evidence Chain module anchors measurement and seal-verification data for each material batch, giving inspectors a tamper-evident basis for the balance.
04.
The DID and VC Ledger issues verifiable credentials to IAEA inspectors, so safeguards access is authenticated without exposing the whole network.
05.
Inspectors query the current material balance and custody chain live, replacing months-long reconciliation of paper and internal digital records.
06.
Fresh fuel, irradiated fuel, and spent fuel are linked as one continuous record, so custody is provable from fabrication through final disposal.
Follow a single fuel assembly from fabrication through reactor use to spent fuel storage under continuous safeguards.

Cerulea decomposes nuclear material accounting into modular contracts. Each layer registers material, transfers custody, verifies the balance, and grants inspectors credentialed access.
Nuclear material accounting is a horizontal capability. Here is how different actors in the fuel cycle put the shared ledger to work.
Maintain a continuous material balance across fabrication, reactor, and storage, so custody is provable at every transfer and missing declarations cannot accumulate.
Key Asset Types
Give IAEA and national inspectors real-time, credentialed access to material accounting, completing inspections in days from on-chain records.
Key Asset Types
Link spent fuel to its full history from fabrication, holding a continuous custody record through interim storage and final disposal.
Key Asset Types
Whether you are bridging facility material accounting systems or letting inspectors verify natively with credentials, Cerulea routes both into one safeguards ledger.
For fuel cycle facilities on internal accounting systems. Material movements are translated into signed on-chain custody records through the API gateway.

The legacy timeline reflects nuclear safeguards integration benchmarks. Wiring facility accounting systems, building custom balance logic, and shipping credentialed inspector access for an average program takes a baseline of 10 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your custody and balance rules into pre-audited WebAssembly binaries and provisions the safeguards ledger instantly.
