301 nuclear sites and 779 reactor units worldwide on an interactive globe, with a timeline running from 1954 to today. Every unit has a technical record built from IAEA PRIS, Global Energy Monitor and Wikidata, cross-checked and corrected against primary sources. There's an animated wiki explaining how each reactor family works and a live signals engine that ingests public feeds to detect outages, power changes and regulatory events. Built by a nuclear engineer. Free, bilingual, no signup.

📝 Summary

Reactor Atlas is an interactive 3D globe mapping all 301 nuclear sites and 779 reactor units worldwide since 1954. Core features include a historical timeline, detailed technical records cross-verified from IAEA PRIS, Global Energy Monitor, Wikidata and primary sources, an animated wiki explaining reactor families, and a live signals engine detecting outages, power changes and regulatory events from public feeds. Built by a nuclear engineer, it is free, bilingual and requires no signup. It solves key pain points of fragmented, inaccessible and overly technical nuclear data by delivering visual, accurate, educational insights. Value proposition: democratizing nuclear science and energy transparency for research, education and public understanding.

📈 Market Timing

Favorable for 2025-2026 due to global nuclear renaissance driven by clean energy demands, AI/data center power needs, net-zero policies, and energy security concerns. Technology for interactive data visualization is mature, while public interest in transparent nuclear info is rising amid new reactor builds and SMR development. Excellent Timing.

✅ Feasibility

High. Technical difficulty is manageable with established webgl/3D libraries and public data APIs. Low ongoing operational costs as a web app; supply chain irrelevant. Compliance risks low since data is public, though verification is essential. Strong team fit with nuclear engineer founder. Excellent scalability potential for global users. High.

🎯 Target Market

Main segments: STEM educators/students, energy researchers, nuclear engineers, policymakers, journalists and science enthusiasts. Industries: Education, Scientific Research, Energy Policy, Media. Geographically global with focus on US, Europe, China, India and other nuclear nations. Estimated market size: Niche; broader edtech/science visualization TAM ~$10B+, nuclear-specific SAM ~$100M, SOM ~$5-10M. Core pain points: lack of unified, visual, real-time nuclear infrastructure data. Willingness to pay: moderate for premium institutional/enterprise features; currently free drives adoption.

⚔️ Competition

Low. Direct competitors: 1. IAEA PRIS (pris.iaea.org), 2. Global Energy Monitor Nuclear Tracker (globalenergymonitor.org), 3. World Nuclear Association resources (world-nuclear.org), 4. Nuclear Power Database by WNA/others. Advantages: superior interactive 3D globe+timeline integration, animated educational wiki, unique live signals engine, all free/no-signup with cross-verified data. Disadvantages: potentially less official depth than IAEA; relies on public sources. Strong differentiation through usability and visualization.
