Nuclear Issue: What´s Brazil really hiding?

According to the website Brazzil, it was aired by LatinNews:
That publication reported that the IAEA inspectors had finished their tour of Brazilian nuclear facilities and that IAEA would announce their findings by the end of November.

But at the end of November, an official with the IAEA told COHA that “Brazil is a continuing issue” and that the agency will carry on its review of its findings until satisfied with the depth and scope of the result. However, the agency could not give a timetable for the release of the final report.

My point: Brazil has no such "new method" or a "revolutionary process" of uranium enrichment. The reason to covert the process keeping out of sight ftom IAEA inspectors is simple: West Germany Companies has sold forbidden (by NATO) equipments and nuclear plant pieces. It was stablish that certain sensitive pieces - that could be use to another purpose than peaceful energy generation - must be kept away from third world countries.
If IAEA inspectors saw these they would know where they come from and who sold them to Brazil.
In this case Brazil would lost the contract support agreement with these suppliers...
It was a simple question of maintaining the support contract working.
We know the explosive outcome of such kind of problems.
