Diamante Energia is evaluating a small modular reactor at its Jorge Lacerda coal-fired complex in Capivari de Baixo, Santa Catarina: the regulator ANSN visited in October 2025 and, on 26 May 2026, began a formal consultation requested by Diamante on the requirements for a preliminary site licence, and in September 2026 Diamante signed a letter of intent with the IAEA and ABDAN to assess the conversion of one unit. No reactor design or investment decision has been made, Rosatom says it has offered a RITM-family plant.
