Operating1circle area ∝ site capacity Coastlines, borders and lakes: Natural Earth (1:10 million, public domain), which is generalised, so a coastal plant can sit a couple of kilometres off its true shoreline. Site positions: Global Nuclear Power Tracker.

Operating fleet by type: PWR (2). Principal operator: Eletrobras Eletronuclear.

The National Energy Plan 2055, approved in September 2026, projects that up to 14 GW of nuclear capacity, including small modular reactors, could become viable. As of July 2026 the energy policy council had taken no decision on completing the Angra 3 unit. Policy position as read on 2026-11-03: World Nuclear Association, Nuclear Power in Brazil (page dated 2026-10-23).

Share of electricity from nuclear power

In Brazil, nuclear plants generated 2.1% of electricity in 2025, about the same as 2.5% in 2015. The share peaked at 4.4% in 2001, so it is 2.2 percentage points below its high.

Fuel supply exposure

The fuel families Brazil's operating reactors take, and the fabricators our sources document as able to make each. This is capability, not contracts: it does not say who actually supplies a given plant.
