Our data

What it is

The dataset holds every published fact: companies, facilities and the links between them, with the public source of each fact. It covers the US nuclear industry. A new release comes out each month.

It leaves out our internal review notes and other publishers' quote text. Each fact points to its source document instead.

Five tables, linked by each company's and facility's slug, which is also the end of its page address here.

• Companies: slug, name, legal_name, aliases, website, description, hq_city, hq_state, country_code, founded_year, status, buckets, roles, technologies, checked_on, url
• Facilities: slug, name, level, site_slug, facility_type, status, technology, reactor_type, capacity_mw, nrc_docket, eia_plant_id, city, state, country_code, latitude, longitude, checked_on, url
• Relationships: id, type, from_slug, to_table, to_slug, ownership_pct, description, started_on, ended_on, checked_on
• Sources: id, url, title, publisher, document_type, published_on, accessed_on
• Evidence: fact_table, fact_key, fact_part, source_id

Each column is described in the release's data dictionary.

How to cite

Say which release you used and the day you downloaded it:
