Demand
Modelling

Translating programme schedules into commodity-level supply chain demand — giving programme teams, government bodies, and regional agencies a clear, data-driven view of what is needed, when, and from which tier.

What It Is

From Programme Schedule
to Supply Chain Reality

Major nuclear and energy infrastructure programmes represent enormous, complex supply chain demands — spread across hundreds of commodity types, multiple tiers, and decade-long delivery windows. Without modelling that demand in advance, programme teams face supply chain gaps, and UK manufacturers miss the preparation time they need.

NucCol's demand modelling capability takes programme data — schedules, bill of materials, technical specifications, and volume assumptions — and translates it into a structured, commodity-level picture of supply chain demand over time. The result is a shared, evidence-based view that programme teams can plan against and suppliers can prepare for.

Proprietary Methodology
Developed and refined across multiple major UK nuclear programmes — including SMR and large-scale new build.
Commodity-Level Granularity
Demand broken down by component, system, and subsystem — not just high-level categories.

What We Model

Demand modelling spans the full breadth of nuclear and energy infrastructure commodities — from structural civil works through to specialist nuclear-grade components and systems.

⚙️

Mechanical Systems

Pumps, valves, heat exchangers, pressure vessels, and associated mechanical plant.

⚡

Electrical & Instrumentation

Switchgear, transformers, cabling, control systems, and instrumentation packages.

🏗️

Civil & Structural

Concrete, reinforcement, structural steelwork, and modular civil construction elements.

🔩

Fabrication & Pipework

Nuclear-grade pipework, pressure-retaining fabrications, and specialist weld assemblies.

🛡️

Nuclear-Specific Components

Fuel assemblies, control rod drives, reactor vessel internals, and shielding systems.

🔋

Energy Storage & Power

Backup power systems, battery arrays, diesel generators, and UPS infrastructure.

🚧

Module Build

Modular construction packages — MEP modules, structural modules, and pre-fabricated assemblies.

🌊

Cooling & HVAC

Cooling towers, heat rejection systems, HVAC plant, and associated process systems.

The Process

How Demand Modelling Works

A structured engagement that takes programme inputs and produces a validated, actionable demand picture — typically delivered over six to twelve weeks depending on programme complexity.

01

Programme Data Gathering

We work with programme teams to gather and structure the inputs — schedules, bill of materials, technical specifications, build sequences, and volume assumptions. Where data gaps exist, we apply validated assumptions based on comparable programmes.

02

Commodity Taxonomy & Structuring

Raw programme data is mapped to NucCol's commodity taxonomy — a structured hierarchy of components, systems, and subsystems that enables consistent comparison across programmes and developers.

03

Demand Curve Modelling

Demand is modelled over time — by commodity, by tier, and by programme phase — producing demand curves that show peak requirements, lead time windows, and critical path supply constraints.

04

Supply Base Gap Analysis

Modelled demand is cross-referenced against NucCol's supplier database and SCRL assessment data to identify where UK supply capability exists, where it is marginal, and where significant gaps or single-source risks remain.

05

Scenario Modelling

Where programmes are uncertain in scope or timing, we model alternative scenarios — enabling planners to understand how demand shifts under different build rates, technology choices, or policy assumptions.

06

Reporting & Visualisation

Outputs are delivered as structured data, charts, and written reports — formatted for programme teams, government briefings, or public consultation depending on the client's needs. Interactive visualisations are available for ongoing live access.

What You Receive

Demand Modelling Outputs

Structured, actionable deliverables that can feed directly into programme planning, procurement strategy, regional industrial policy, and supplier development programmes.

Commodity Demand Report

A full, structured breakdown of demand by commodity type across the programme lifecycle — with volume estimates, timing windows, and tier-level attribution.

Demand Curve Visualisations

Graphical demand curves by commodity, phase, and year — showing peak demand windows, lead time criticality, and cumulative programme requirements.

Supply Gap Analysis

Identification of commodities where UK supply capability is insufficient, marginal, or concentrated in single sources — with risk ratings and recommended intervention priorities.

Scenario Comparisons

Side-by-side demand modelling under alternative programme assumptions — supporting robust planning under uncertainty and informing technology choice decisions.

Bill of Materials Mapping

Structured bill of materials data mapped to NucCol's commodity taxonomy — reusable across multiple planning, procurement, and supplier engagement activities.

Executive Summary

A concise, non-technical summary of key findings — suitable for government briefings, board presentations, and public communications on UK content and supply chain readiness.

Who It Serves

Built for Programme Planners at Every Level

Demand modelling is commissioned by a wide range of organisations — wherever there is a need to understand future supply chain requirements before they materialise.

Nuclear Developers

Programme Teams & Primes

Build confidence in your supply chain strategy before procurement begins. Identify single-source risks, capacity constraints, and lead time issues while there is still time to act.

Public Sector

Government & Policy Bodies

Understand national and regional supply chain demand to inform industrial strategy, target development funding, and maximise UK content across major infrastructure programmes.

Regional Development

LEPs & Regional Agencies

Map programme demand against regional supply base capability to target skills investment, infrastructure planning, and business support where they will have the greatest impact.
