Nuclear Safeguards Layer

Account for every gram.
Prove custody to the IAEA.

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.

The Foundation

The Execution Mechanics

Replace fragmented material records with a continuously verifiable, inspector-accessible chain of custody.

01.

Material Balance Ledger

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.

Custody Transfer Sealing

Each transfer from enrichment to fabrication to reactor to storage is co-signed and sealed, making a missing declaration structurally impossible to hide.

03.

Evidence Anchoring

The Evidence Chain module anchors measurement and seal-verification data for each material batch, giving inspectors a tamper-evident basis for the balance.

04.

Inspector Identity

The DID and VC Ledger issues verifiable credentials to IAEA inspectors, so safeguards access is authenticated without exposing the whole network.

05.

Real-Time Safeguards View

Inspectors query the current material balance and custody chain live, replacing months-long reconciliation of paper and internal digital records.

06.

Lifecycle Continuity

Fresh fuel, irradiated fuel, and spent fuel are linked as one continuous record, so custody is provable from fabrication through final disposal.

The Fuel Custody Lifecycle

Follow a single fuel assembly from fabrication through reactor use to spent fuel storage under continuous safeguards.

Smart Contract Anatomy

Cerulea decomposes nuclear material accounting into modular contracts. Each layer registers material, transfers custody, verifies the balance, and grants inspectors credentialed access.

Applicability Across the Spectrum

Nuclear material accounting is a horizontal capability. Here is how different actors in the fuel cycle put the shared ledger to work.

Fuel Cycle Facilities

Maintain a continuous material balance across fabrication, reactor, and storage, so custody is provable at every transfer and missing declarations cannot accumulate.

Network & Execution Architecture

Whether you are bridging facility material accounting systems or letting inspectors verify natively with credentials, Cerulea routes both into one safeguards ledger.

Track A: Facility Accounting Bridging

For fuel cycle facilities on internal accounting systems. Material movements are translated into signed on-chain custody records through the API gateway.

Technical Methodology

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.
