On 19 November 2021 Indústrias Nucleares do Brasil (INB), the company that operates the uranium enrichment plant in Resende, announced that it will launch a ninth centrifuge cascade shortly. According to INB, the cascade will increase the plant's capacity by 5 percent. Another cascade is expected to become operational in 2023, increasing the capacity by further 5 percent. IND estimates that this will allow the plant to cover about 70 percent of the demand for the Angra 1 reactor.
The current capacity of the Resende plant is estimated to be 45 tSWU/year. The installation of two new cascades will bring the capacity to about 50 tSWU/year.
The Resende plan began operations in 2009 and its capacity have been gradually increasing. The seventh cascade became operational in 2018. Apparently the eighth cascade was added at some point after that.
