Decommissioning Escrow Layer

Ring-fence the fund.
Release on milestones only.

Deploy a regulator-visible escrow fund for nuclear plant decommissioning, with funds released only against verified decommissioning milestones. The fund is held with full regulator visibility and portions are released as each milestone is reached when the plant is eventually retired.

The Foundation

The Execution Mechanics

Give regulators continuous assurance that decommissioning funds are intact and released only against verified progress.

01.

Ring-Fenced Escrow

Escrow and Conditional Settlement holds decommissioning contributions in a dedicated fund the operator cannot draw from except against verified milestones.

02.

Milestone Gating

Each release is gated on a decommissioning milestone, so funds move only when defined work is completed and confirmed decades into the future.

03.

Regulator Visibility

Compliance Attestations give the regulator continuous visibility into the fund balance and every release, replacing periodic assurances with a live view.

04.

Verified Progress

Milestone completion is attested before release, so a payment reflects real decommissioning progress rather than a claim.

05.

Contribution Tracking

Every contribution over the plant's operating life is recorded on-chain, so the fund's adequacy is auditable at any point in the decades-long timeline.

06.

Immutable Fund History

The Audit Logs module retains contributions, attestations, and releases, giving future regulators a complete, tamper-evident record of the fund.

The Decommissioning Fund Lifecycle

Follow the fund from operating-life contribution through a verified milestone to a gated release at retirement.

Smart Contract Anatomy

Cerulea decomposes decommissioning escrow into modular contracts. Each layer holds contributions, defines milestones, verifies progress, and releases funds under regulator visibility.

Applicability Across the Spectrum

Milestone-gated decommissioning escrow is a horizontal capability. Here is how different actors in the fund's lifecycle put the shared ledger to work.

Plant Operators

Contribute to a ring-fenced fund over the operating life and draw against verified milestones at retirement, demonstrating fund adequacy without discretionary access.

Network & Execution Architecture

Whether you are bridging an operator's treasury systems or letting regulators attest milestones natively, Cerulea routes both into one decommissioning escrow.

Track A: Treasury System Bridging

For operators on legacy treasury and fund accounting systems. Contributions are translated into signed on-chain escrow records through the API gateway.

Technical Methodology

The legacy timeline reflects regulated escrow integration benchmarks. Wiring treasury systems, building custom milestone-gating logic, and shipping a regulator visibility layer for an average fund takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your milestone and release rules into pre-audited WebAssembly binaries and provisions the escrow ledger instantly.
