nuclear power plant of Angra 2 started its commercial operations. Under President Lula da Silva (2003–2011), the nuclear program was revived. INB's Nuclear Fuel Factory (Fábrica de Combustível Nuclear – FCN), a commercial-scale uranium enrichment facility, became operational in 2004. However, disagreements between Brazil and the IAEA regarding the inspection procedures delayed the full start of operations. Brazil was reluctant to grant IAEA inspectors full visual access to its centrifuges, which were hidden by 2-meter (6.6-foot) high panels, as Brazilian authorities argued that a superior centrifuge technology had been developed in the country and it was necessary to protect these industrial secrets. After months of impasse, Brazil agreed to allow increased – but not full – visual access to the centrifuges and other industrial equipment by reducing the size of the panels covering the machinery. As a member of the Ministry of Science and Technology reportedly said at that time, Brazil was lifting the skirt and lowering the top a little, but retaining its secrets. Budgetary constraints also postponed the beginning of industrial enrichment operations at the FCN. In 2006, the Minister of Science and Technology officially inaugurated the complex, located in Resende, Rio de Janeiro. A first enrichment cascade started in May 2006 at the Resende facility. A second one was activated in November 2009 and, two years later, a third cascade was made operational. Currently, there are four cascades in operation, which allow INB to enrich approximately 14% of Angra 1's annual uranium needs. The other 85% continues to be enriched overseas, mainly in Canada and Europe. In 2007 Brazil launched the National Energy Plan 2030 (Plano Nacional de Energia 2030 – PNE 2030). This plan states the need to increase the energy production in Brazil and proposes that an additional nuclear energy capacity of 5,345 megawatts (MW) be installed by 2030. In order to make it feasible, the plan supports the completion of Angra 3 – whose construction started in 2010 and it is still underway – and recommends the construction of four nuclear power plants across the country. In 2011, the electricity generated by the nuclear power plants of Angra 1 and Angra 2 represented 2.7% of the national energy output, approximately 14 tWh. While Angra 3 remains under construction and is expected to become operational in 2018, there have been no moves to build the four new nuclear plants as outlined by PNE 2030. In
