Romania plans to shut Cernavoda unit 1 for refurbishment in 2027-2029 and return it to service in 2030 for a further 30 years. The Doicesti NuScale SMR project received a shareholder investment decision in February 2026, but by October 2026 over 80% of its conditions remained unmet. Policy position as read on 2026-11-03: World Nuclear Association, Nuclear Power in Romania (page dated 2026-11-02).

Share of electricity from nuclear power

In Romania, nuclear plants generated 20.5% of electricity in 2025, up from 17.7% in 2015. The share peaked at 20.8% in 2020, so it is 0.3 percentage points below its high.

Share of the country's total electricity generation that came from nuclear plants, by calendar year (1995 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.
