Executive summary — The Nuclear Energy Intelligence Portal is an interactive geopolitical brief that maps the structural constraints governing the future of global zero-carbon baseload power. It serves energy strategists, policy analysts, and capital allocators by translating reactor fleets, fuel-cycle concentration, and heavy-manufacturing chokepoints into decision-grade visual intelligence — exposing where dependence, deficit, and demographic decay collide.
- Exposure ranking array — ranks nations by absolute dependence on nuclear generation versus structural capacity, separating large grid-buffering fleets from single-site national single-points-of-failure.
- Supply-chain chokepoint map — a dark, interactive geospatial view that toggles between operating reactors and the ultra-heavy forging nodes (Japan, China, Russia, France) that physically gate Gen-III+ construction.
- Capital destruction tracker — a delay-versus-cost matrix visualizing the schedule and budget overruns endemic to Western greenfield reactor builds.
- The retirement cliff — fleet age profiling that surfaces the medium-term baseload risk as the 1970s/1980s build cohorts approach their 60-year terminal limits.
- Fuel-cycle concentration matrix — stage-by-stage breakdown of mining, conversion, and enrichment leadership, highlighting Russian dominance of the SWU bottleneck.
- Regional target dossiers — focused deep dives, including the Akkuyu VVER build-out anchoring Türkiye's industrial energy future.
- Methodology in the open — every assessment is framed by the Monarch Castle Tri-Color Severity Scale, exposed in an in-app methodology memo.
The portal is a single-page analytical brief composed of linked intelligence modules. Each module reads a curated dataset and renders it through a purpose-built visualization rather than a generic chart.
- Exposure Table — country-level nuclear share, active reactor count, and net capacity, ranked to distinguish dependence from scale.
- Interactive Map — a label-stripped dark Leaflet map plotting reactor sites and, on toggle, the ultra-heavy forging and fuel-cycle chokepoints that constrain new build.
- Capital Scatterplot — plots project cost against schedule delay to make Western greenfield cost-overrun patterns legible at a glance.
- Fuel Cycle Matrix — decomposes the front end of the fuel cycle (mining → conversion → enrichment) into per-stage market leadership.
- Retirement Cliff Chart — age-profiles the operating fleet to expose the coming wave of terminal-limit retirements.
- Türkiye Dossier — a regional strategic deep dive on the Akkuyu VVER program.
- Featured Reports & Policy Memo — short narrative briefs and a methodology modal explaining the assessment framework.
Per Monarch Castle doctrine — evidence before assertion. The portal is driven by versioned, analyst-curated reference datasets committed in-repo under src/data/, so every figure on screen is traceable to a specific record in source control:
| Dataset | Records | Key fields |
|---|---|---|
exposure.json |
National nuclear dependence | countryName, nuclearSharePct, activeReactorCount, activeNetCapacityMw |
reactors.json |
Reactor sites & units | location, lat/lng, capacityMw, gridShare, buildYear, capitalCostBillion, delayYears, supplyChainRisk, capacityHistory |
chokepoints.json |
Heavy-forging / fuel-cycle nodes | name, country, lat/lng, status, type, description |
uranium_cycle.json |
Fuel-cycle stages | process, unit, per-stage leaders[] with sharePct |
Assessment methodology. Industrial processes are scored against the Monarch Castle Tri-Color Severity Scale — IMPOSSIBLE / EXTREMELY DIFFICULT / RESTRICTED — derived from historical permitting success rates, litigation velocity, and capital-formation requirements under modern Western regulatory regimes. The framework is documented in the in-app Intelligence Methodology memo.
Provenance roadmap. The current datasets are point-in-time snapshots curated by analysts. In line with house doctrine, each record should carry explicit
source,source_url,collected_at, andmethodfields; extending the schemas with these provenance columns is the next planned hardening step.
