Provenance Record

Well-structured News article at 682 words (within 400-1200 range). Good use of Overview, What We Know, What We Don't Know, and Analysis sections. Appropriate technical depth on nuclear energy policy.

Source 1 (IAEA): Accessible. Confirmed: 413 reactors, 377 GW, 31 countries, 69 under construction in 16 countries, ~10% of global electricity, ~25% of low-carbon power, 'nearly 40 countries' pledge, China 4th-gen reactor and Linglong One, EU 200M euro guarantee and SMR strategy, DiNanno quote. NOT confirmed: 140 companies or Google/Amazon/Meta mentions, Germany's position, US 'quadrupling' pledge. Source 2 (Elysée declaration): Accessible. Lists 34 signatory countries. CRITICAL: Brazil is NOT among the 34 listed signatories (China, Belgium, and Italy ARE listed). Confirmed: nuclear applications beyond electricity (industrial heating, AI data centers, hydrogen, desalination, agriculture), deep geological disposal, independent regulatory authorities. NOT confirmed: COP28 '25 original signatories' figure, von der Leyen quote. Source 3 (Diplomatie.gouv.fr): Accessible but provides only general summit program information. Confirms ~10% of global electricity. No specific claims about signatories, commitments, or quotes.

CRITICAL: Brazil is listed as a new signatory in the title and opening paragraph, but the Elysée declaration (cited as the source for the endorsement) lists 34 countries and Brazil is NOT among them. This is the article's most prominent claim and it is not supported by the cited source. SECONDARY: Several claims lack support from any cited source: (1) 'Over 140 nuclear companies and major energy consumers including Google, Amazon and Meta' — not in any source; (2) Von der Leyen's 'strategic mistake' quote — not in any source; (3) US pledge to 'quadruple' nuclear capacity — IAEA mentions DiNanno but not a quadrupling pledge; (4) Germany's environment minister arguing against nuclear — not in any source; (5) Brazil's 90% clean electricity, uranium reserves, and Amazon SMR proposals — not in any source; (6) '25 original signatories at COP28' — not confirmed by any source (though this is widely known background).

The article is well-written and covers an important energy policy event, but has significant source-verification gaps. The most critical issue is that Brazil — featured prominently in the title — is not listed as a signatory in the declaration text the article cites. Multiple other claims (von der Leyen quote, US quadrupling pledge, 140 companies, Germany's position) cannot be traced to any cited source. REQUEST_CHANGES to address these factual and sourcing gaps.
