Construction work on Angra 3 has resumed! With German technology, the plant will generate 12 million megawatt hours a year!

A Eletronuclear informed that on Tuesday (15), at 15:36 pm, the Angra 2 nuclear power plant was disconnected from the National Interconnected System (SIN). The reason was the automatic tripping of the turbogenerator set, in the non-nuclear part of the plant, caused by the activation of the fault protection for earth of the main generator rotor.

A nuclear power plant returned to operation last Monday (14) after having been stopped for four days because of the same problem. Eletronuclear professionals are already working to identify the cause and establish a forecast for the return of Angra 2 to the SIN.

Resumption of concreting marks the resumption of work on Angra 3

Eletronuclear carried out on the afternoon of November 11, at the Angra dos Reis nuclear power plant, the restart of the concreting process of the Angra 3 power plant. resumption of civil works at the plant, expected to be ready in 2028. The company's new president, Eduardo Grand Court, was present at the occasion.

Preparations for restarting concreting began in February this year with the signing of the contract between Eletronuclear and the Agis consortium, comprising Ferreira Guedes, Matricial and ADtranz. Since then, the winning companies of the bidding acted in the preparation of the construction site for the resumption of the development, which included the assembly of a concrete plant on site.

The generation of Angra 1, 2 and 3 together will be equivalent to 60% of the energy consumption in the state of Rio de Janeiro and 3% in Brazil!

The launching of the first concrete started the Angra 3 Critical Line Acceleration Plan, which aims to conclude the civil works of the main buildings of the plant. This includes the reactor building and other facilities linked to nuclear safety.

Additionally, we bring it is planned to carry out a relevant part of the electromechanical assembly, such as the closure of the containment, steel ball located inside the reactor building, and the installation of important equipment, such as the spent fuel pool, the polar bridge and the semi-gantry crane.

With German technology, Angra 3 will generate 12 million megawatt hours per year, enough energy to supply the residential consumption of the entire North region and almost the entire Midwest region of Brazil. The generation of Angra 1, 2 and 3 together will be equivalent to 60% of the energy consumption of the state of Rio de Janeiro and 3% of the country.
