The main aim of the project was to replace existing generators with new ones, thereby ensuring that the power plant operates at 100% capacity.

Iberdrola group’s engineering subsidiary ran the technical management of the construction of the project, spearheading the engineering work, planning and construction supervision.

Future priorities will include increasing the generator group’s electricity output capacity.

In the first phase, Iberdrola Ingeniería studied the geometric specifications of both the new and old generators, evaluating possible obstacles that might interfere with their dismantling and transport, and what structures might be necessary to lift and move the old generator out of the building and the new one into the building. In addition, the routes into and out of the building were prepared, along with assembly procedures and planning for the new systems to be installed.

In the second phase, the reactor’s containment structure was opened, the old generators removed and the electromagnetic assembly of the new ones was undertaken. Once these works had been finished, tests were carried out to assure the correct functioning of the hydraulics and the integrity of the containment structure.

During the assembly of the generators, specific methods for moving heavy loads were developed and deployed, adapted to the specifications of the Angra nuclear power plant. The load in question surpassed 350 tonnes and was over 21 meters long.

In addition, Iberdrola Ingeniería was awarded a three year tender to carry out ultrasound inspections of the low pressure turbine rotors of units 1 and 2 of Brazil’s nuclear installation.
