Atucha III

On February 1, 2022, Nucleoeléctrica Argentina and the Chinese National Nuclear Corporation (CNNC) signed the contract for the construction of Atucha III, a 1,200 MWe reactor with an initial useful life of 60 years to be installed at the Atucha Nuclear Complex in the locality of Lima, province of Buenos Aires. The project involves an investment of $8.3 billion and will allow an increase of more than 60% in electricity generation from nuclear sources.


The EPC (engineering, purchasing and construction) contract provides for the provision of engineering, construction, acquisition, start-up and delivery of an HPR-1000 type plant, which will use enriched uranium as fuel and light water as coolant and moderator.

The construction works will begin at the beginning of 2023 and will require the creation of more than 7,000 jobs during the work peak, 700 permanent jobs for its operation and an approximate integration of the 40% with national suppliers.
