Argentine nuclear power plant operations and upgrades

Overview

Argentine nuclear facilities managed by Nucleoeléctrica Argentina have demonstrated high operational performance and significant progress in infrastructure longevity projects.

In the second quarter of 2026, the Atucha II and Embalse plants achieved top global performance rankings according to the World Association of Nuclear Operators (WANO) PI-Index. Atucha II reached a perfect score of 100 points, while Embalse scored 98.4 points. These results follow a record-breaking production year in 2025.

Concurrently, the Atucha I plant is undergoing a life extension project following its September 2024 shutdown. The facility has completed over 17,000 tasks, including reactor protection upgrades, electrical grid modernization, and the construction of a new engineering building. The project aims to extend electricity generation capacity by 20 years, with nuclear fuel reloading scheduled for early 2027 to facilitate a return to active power generation.
