Eletronuclear

Eletronuclear is the nuclear power subsidiary of Eletrobras, responsible for generation of nuclear electricity in Brazil. It operates the Angra nuclear power plants (Angra 1 and Angra 2) and oversees the construction of Angra 3. The company supplies electricity to the national interconnected system, serving residential, industrial, and commercial consumers across the country. Its core activity involves operating nuclear reactors, managing nuclear fuel, and ensuring the safety and security of nuclear facilities. The company also engages in research and development related to nuclear technology and supports the country's nuclear policy objectives.

Eletronuclear's facilities are located in Angra dos Reis, Rio de Janeiro state, and its generation capacity contributes to Brazil's low‑carbon electricity supply. As a state‑owned enterprise under Eletrobras, it benefits from the parent company's extensive infrastructure and grid integration capabilities. The company employs a specialized workforce of engineers, technicians, and safety professionals trained in nuclear operations. Its regulatory oversight involves multiple Brazilian agencies, including the National Nuclear Energy Commission (CNEN) and the Ministry of Mines and Energy, ensuring compliance with national and international safety standards.

Eletronuclear is the sole entity in Brazil licensed to operate commercial nuclear power reactors, giving it a unique position in the nation's energy sector. Its expertise encompasses the full lifecycle of nuclear power generation, from fuel handling to waste management, and it maintains rigorous safety culture protocols. The subsidiary also contributes to the diversification of Brazil's energy sources. Its operational resilience was highlighted during the 2021 ransomware incident, where administrative systems were affected but nuclear plant operations continued uninterrupted, demonstrating effective segregation of critical control networks.

Eletronuclear is a wholly owned subsidiary of Eletrobras, and its financial and operational reporting is consolidated within Eletrobras group statements. The company's headquarters are situated in Brazil, reflecting its national mandate. Governance includes a board of directors appointed by the parent company and oversight from federal government bodies concerned with energy policy and nuclear security. This structure aligns Eletronuclear's objectives with Brazil's broader energy planning and nuclear non‑proliferation commitments.
