 enrichment plant in May 2006. Brazil's enrichment technology development, and the plant itself, involved substantial discussions with the IAEA and its constituent nations. The dispute came down to whether IAEA inspectors would be allowed to inspect the machines themselves. The Brazilian authorities at first did not allow the inspection of the centrifugal cascade halls, arguing that this would reveal technological secrets (probably relating to the use of a magnetic lower bearing in place of the more common mechanical bearing).

The Brazilian authorities stated that, as Brazil is not part of any "axis of evil
