The nuclear inventory, resolved
One reading per fact, aligned to the same unit, with its source and date. The map, the sheets, monitoring and alerts all drink from the same process.
What is published today
What you can query
Each layer has its own sheet, cadence and sources. The method is the same.
Power reactors
Status, type, net and gross capacity, grid and commercial dates, owner and operator. A timeline since 1954.
Open the map →Research reactors
Thermal power, type, status and purpose, including radioisotope production. A sheet per reactor and per vendor.
See research →Fuel cycle
Mining, conversion, enrichment, fabrication, reprocessing, heavy water, storage and uranium deposits.
See fuel →Operational signals
Outages, returns, power changes, nearby earthquakes and regulatory findings, ingested from each operator's and regulator's own channels.
See signals →Official releases
Notes from operators, regulators and governments, plus World Nuclear News as the one secondary source, always with a link to the original.
See monitoring →Reactor-produced radioisotopes
The Mo-99, I-131 and Lu-177 chain: reactors, processors and supply notices. Every capacity figure cites the report and the year.
See isotopes →Electricity mix by country
Nuclear's share of electricity generation, from Ember and Our World in Data, kept as distinct readings.
See countries →Alerts
An email when a unit, a country or a signal type moves. The product is the detection and notice service, not a licence to the underlying data.
Set up alerts →Cadence
Inventory
Once a month, with an editorial review.
Hourly signals
Every hour, from regulators and grid and plant operators.
Daily signals and releases
Every six hours.
Alerts
Instant, daily or weekly, as chosen.
What it is for
A figure you can stand behind
Procurement, a desk or a newsroom: every number carries a source, a date and a basis. When two readings disagree, both are in view.
A notice with the original
The alert names the fact and opens the operator's or regulator's own notice. It does not replace the official channel.
A map that shares
Every important view has a short link and a card. A link without a language is in English.
How a figure is chosen
When two sources disagree, the reading with an effective date wins. The authority order is published, by type of fact. Sources, licences and definitions live on the methodology page.
Enterprise use
Monitoring, alerts and coverage conversations: through fedecaccia.com. That is the service — detection, resolution and notice. Third-party data stays under each source's own licence.
