license was renewed. According to an article in Folha de S.Paulo, the report authors resigned from their positions. On 15 May 2009, a human error during a decontamination procedure at Angra 2 resulted in the release radioactive particles, affecting – but not severely contaminating – the six workers located near the incident site. Even though the Brazilian company in charge of nuclear energy production Eletrobras Eletronuclear claimed to have reported the accident to relevant authorities when it occurred, news about it only surfaced the media 11 days later. In Caetité, on 2 May 2010, a pipe broke at INB and 900 liters of uranium liquor spilled onto the soil. On 18 October 2012, an operational fault at the INB mine in Caetité, poured roughly 100 kilograms (220 pounds) of uranium onto the ground. INB claimed that it followed requisite protocol and cleaned the area. On 26 June 2013, a man who works for INB as a night watchman at Caetité's Uranium Concentrate Unit fell into a pool filled with 20,000 m³ of radioactive fluids. The incident became public through a local NGO, which reported the worker's fall and denounced the insufficient safety measures in place at the uranium plant; such as the absence of guardrails around radioactive storage pools. After the event made the news, INB released a note in which the company affirmed it had granted medical assistance to the worker. According to this statement, the worker went through checkups and his health has not been affected. Oversight, control and nuclear security While CNEN is responsible for promoting and fostering nuclear industry in Brazil, it also supervises and regulates the country's nuclear sector—a duality of responsibilities that can undermine the independence of the supervision system. It has also been pointed out that this goes against Article 8 of the Convention on Nuclear Safety, which states that "each Contracting Party shall take the appropriate steps to ensure an effective separation between the functions of the regulatory body and those of any other body or organization concerned with the promotion or utilization of nuclear energy." Brazil has been a signatory to that accord since 2 June 1997. Since early 2013, the Brazilian government is weighing a proposal to establish a nuclear regulatory agency. Some in the nuclear sector have voiced their support for the measure, which would separate regulation, licensing and control of nuclear activities from the fomentation, promotion and support
