Model Supply Security Across the Full Fuel Cycle
Design, stress-test and quantify nuclear fuel security strategies from U₃O₈ through conversion, enrichment and fabrication — then express the economics in board-ready language.
Ideal For
- Fuel and procurement teams at both single-reactor and multi-reactor facilities
- Organizations that need to move from uranium-only thinking to full fuel-cycle security design
- Teams that must defend inventory, contracting and security-premium decisions at Board or Risk Committee level
- Anyone who needs a practical, Excel-based Framework to model sensitive strategy options without complex IT involvement
What is it?
The TCS Engine™ is an Excel-based modelling environment for security of supply in constrained nuclear fuel markets. It moves beyond single-commodity inventory tracking to give you stage-level visibility and a coherent economic view of the entire front-end fuel cycle.
What it does
You can now:
- Model position and cost at each stage (U₃O₈, Conversion, Enrichment, Fabrication)
- Design and compare multi-dimensional strategies using TCS Prism™
- Reconcile operational reality to policy baseline
- Generate clear Cost of Security, Security Value Delivered, Net Security Position and Security Efficiency outputs for the Board
What the TCS Engine™ Delivers
- Full fuel-cycle position modelling (stage contributions that reconcile to a single Ueq headline)
- Strategy design and comparison through TCS Prism™ (Commercial Optimization + Security Value Optimization)
- Scenario stress-testing against structural market shifts and different security postures
- Operational Control Room view versus Policy Baseline reconciliation
- Board-ready economic outputs (TCS, SVD, NSP, SER and supporting narratives)
Part of the TCS Ecosystem
The Engine sits at the center of the system:
- TCS Framework™ — quantifies the economics of security
- TCS Prism™ — designs and compares strategies across multiple dimensions
- Resilience Pillars™ — diagnoses current operational resilience
- Boardroom Shield™ — translates the outputs into language the Board will accept
It answers an essential board-level question:
"What is the net economic value of our security posture?"
It is the first executive framework that quantifies the economics of security of supply.
"It measures the economics of security itself."
Why This Matters
Traditional metrics still treat cost, inventory and coverage as separate problems. In constrained fuel markets they are not.
Most tools also stop at U₃O₈. Conversion and enrichment constraints are often where the real exposure sits, yet they remain poorly quantified in conventional approaches.
The TCS Engine™ addresses both gaps. It allows you to:
- Model security across the full fuel cycle
- Design strategies across multiple dimensions rather than on a single price or coverage metric
- Reconcile operational reality to policy intent
- Translate the results into a coherent economic story for executive and board decision-making
In a market characterized by structural tightness, policy intervention and long lead times, the ability to design and defend security of supply with stage-level clarity is becoming a practical requirement rather than a theoretical advantage.
How it Works
- Define the security posture: Enter your current or proposed position across the fuel cycle — volumes, stage targets, coverage and key commercial assumptions.
- Review the Cost of Security: See the economic cost of the chosen posture at both stage level and in a single reconciled Ueq view.
- Compare Security Value Delivered: Evaluate what previous decisions have actually delivered in security terms.
- Assess Net Security Position & Efficiency: Understand whether the current or proposed strategy is creating or destroying economic value.
- Design and stress-test alternatives with Prism: Use the Prism dimensions to structure and compare different commercial and security strategies under a range of market conditions.
- Generate board-ready outputs: Produce clear economic results and supporting narrative that can be taken into Board or Risk Committee discussions.
Typical Inputs
The Engine is designed to work with the data fuel teams already hold:
- Annual and stage-level requirements
- Current and target Months of Forward Burn by stage
- Pipeline lag assumptions
- Coverage / uncommitted percentages
- Holding cost and commercial assumptions
- Known supply or capacity constraints
You can start with a simplified view and add stage detail as needed. No complex data architecture is required.
What's Included
- The TCS Engine™ modelling workbook
- Full fuel-cycle and Prism-enabled structure
- Board-ready output views and supporting schedules
- Strategic briefing guide
- Board presentation structure and narrative prompts
Enterprise use across your fuel and procurement team is included.
How it is Delivered
The TCS Engine™ is built natively in an advanced Excel architecture. It does not connect to external servers, APIs, or cloud hosting. This allows your team to input live, sensitive procurement profiles with total peace of mind, knowing your commercial data never leaves your internal network.
Boardroom Shield™
The Engine feeds directly into Boardroom Shield™ — the layer that converts full fuel-cycle analysis and Prism strategy options into language the Board will accept. It answers the practical questions: what the posture costs, what value it delivers, and whether it is justified.
