The nuclear power plant Angra, also known under the original spelling Central Nuclear Almirante Álvaro Alberto ( CNAAA ), is the only commercial nuclear power plant in Brazil. It is located on Praia de Itaorna in Angra dos Reis in the province of Rio de Janeiro. The location between the cities of Rio de Janeiro and Sao Paolo is located in a landslide - hazardous derten bay on the Atlantic coast. Cooling ponds for old fuel rods are only 50 meters from the sea.

The construction of the nuclear plant goes back to an agreement between the German government and the Brazilian military regime in 1975, the nuclear power plant consists of two pressurized water reactors. Angra I, with an installed capacity of 626 MW ( first network synchronization 1982) and Angra II with an installed electrical capacity of 1,275 MW ( first network synchronization 2000). A third reactor, Angra III with a gross electrical output of 1,350 MW, is planned for 1975. Work on this third block were started in 1984 and interrupted two years later due to environmental concerns and financial problems. On 1 June 2010, the construction work for Angra III were officially resumed. The federal government approved for the expansion of an export credit guarantee over 1.5 billion euros, the final loan approval is still pending.

Angra I

The reactor Angra I is a Westinghouse reactor, the Brazil bought in the USA. The " bust - kiln from the seventies " was in 1994 only for 14 days in operation.

Angra II

Angra II was built with German technology (Siemens / KWU) and went in 2000 after 25 years of planning and construction time. 2001 reached 150 liters of radioactive water into the Atlantic Ocean.

Angra III

The technique for Angra III in 1985 bought for 750 million DM and stored since then. For a year fall to $ 20 million cost. That an intended German Hermes export guarantees for Areva / Siemens in the amount of 2.5 billion euros a basis in reports from 2010 has been criticized by environmental groups as a " courtesy report". To remain unclear to what extent the system is secured against aircraft crashes, and if there were, the nuclear expert Helmut Hirsch, " no systematic presentation, which rules and regulations in detail were the extent used. " Even on the basis of an extended report produced in 2012, which had been commissioned by Areva in order to answer fundamental questions left open. For this reason, the German government announced in May 2012, for the time being does not have the desired loan guarantee to decide.

Atom Political Course of the Brazilian government

The negative experience in Angra had the consequence that Brazil ceased all planned construction of nuclear power plants and started no new plans for nuclear power plants.

On 8 May 2007, the Brazilian federal government was known, however, take the frozen since 1986 program for the construction of Angra III and four other power plant units again. According to government estimates, the costs for the completion of Angra III 7 billion Brazilian real (about € 3 billion ) amount. The reason for the resumption of its nuclear program was called threats to the security of supply. Action arises from the problematic approval procedure for two planned hydropower stations in the state of Rondônia, for which consists of government perspective only little hope. We do not want to replace with gas-fired power plants, this generation capacity, for a climate protection reasons and partly because of the large uncertainties for the Brazilian natural gas supply arising from the political situation in the main supplier Bolivia.

2010 supported the German Foreign Minister, Guido Westerwelle, the nuclear course the Brazilian government during a visit in the country and fought for the German nuclear industry. The German government has provided for the reactor, Angra III, a guarantee of 1.3 billion euros in view. With the approval of Angra III, then-President Luiz Inacio Lula da Silva tried with the claim that he could " guarantee that never happens in the Brazil what happened in Chernobyl. Never " to dissipate. Concerns.

Because of the Fukushima nuclear disaster, the federal government intends to examine the German 1.3 - billion - euro export credit guarantee for the construction of Angra III again. In the project, Siemens is involved; responsible is the French nuclear group Areva.

In September 2013 gave Mauricio Tolmasquim, chief of the State Energy Planning Board, announced that the government would waive the construction of four new nuclear reactors by 2030, and instead focus on wind power.
