Methods, scope, corrections

Separate announced from binding.

Every nuclear × large-load deal, its structure, its contractual weight, and what changed, in one free place.

Inclusion rule

We include publicly announced fission deals between a nuclear power provider and a named large-load buyer or developer. Announcements without a named counterparty are excluded. Fusion agreements are excluded from v1 so the technology field stays comparable.

Methodology

Each material figure points to a source entry that states what it supports. Primary sources take priority: company releases, SEC filings, and regulator dockets. Trade press can identify a lead, but never stands alone behind a number. Firm and optioned capacity remain separate in the data and interface.

Corrections

Open a GitHub issue with the deal id, the proposed correction, and a primary source. Issues serve as the tip line. Accepted changes enter the public changelog.
