One Big Beautiful Bill Act (nuclear tax credits; RECA; nuclear MLPs)

What it does

A sweeping reconciliation law that treated energy credits asymmetrically: it terminated wind and solar credits after 2027 but preserved the nuclear ones. New nuclear keeps the 45Y/48E credits if it begins construction before 2034 (then phasing down), with advanced reactors getting extra runway and a new 10% bonus for 'nuclear energy communities.' It also lets advanced-nuclear generators use Master Limited Partnership structures from 2026 (the tax-advantaged setup long enjoyed by oil and gas), while adding Foreign Entity of Concern restrictions. Separately, it enacted the largest-ever expansion of the Radiation Exposure Compensation Act (RECA) — raising payments to $100,000 and broadening coverage for downwinders, uranium workers, and Manhattan Project waste communities.

Why it matters

Cemented nuclear as the politically favored clean-energy technology of the second Trump term. The RECA expansion was the human-facing counterpart to expanding domestic uranium mining.
