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 (1). Principal operator: Closed Joint Stock Company Armenian NPP.

Armenia plans to build a new nuclear plant, which the prime minister said in October 2025 would be a small modular reactor. A US 123 Agreement on peaceful nuclear cooperation was signed in February 2026. Officials have said investment could extend Metsamor's operation to 2036. Policy position as read on 2026-11-03: World Nuclear Association, Nuclear Power in Armenia (page dated 2026-07-10).

Share of electricity from nuclear power

In Armenia, nuclear plants generated 27.0% of electricity in 2025, down from 34.0% in 2015. The share peaked at 42.4% in 2006, so it is 15.4 percentage points below its high.

Share of the country's total electricity generation that came from nuclear plants, by calendar year (2000 to 2025). Amber marks the high point, green the latest year. Source: Our World in Data from Ember and the Energy Institute, CC BY 4.0.

Fuel supply exposure

The fuel families Armenia'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.
