Explosion at Suviana hydroelectric power plant occurred at a very delicate moment. The commissioning of the turbine was underway, the phase that precedes the actual testing.
Expert: "The extraordinary maintenance intervention on the turbine could lead one to think that the problem could concern this type of plant" A similar accident occurred on 17 August 2009 at the Sayano-Shushenskaya power plant in the Russian Federation, caused by the explosion of a transformer. 'No structural but plant critical issues' - expert Aldo Fiori, full professor of hydraulics, maritime constructions and hydrology at the Roma Tre University.. The turbine "could also be thought of as having significant water flows", adds the expert, referring to the fact that the water level continued to rise for a long time on the afternoon of April 10th. The gas mixture could have been induced by the lubricating oils from the bearings in the turbines spilled on the hot parts of the machinery, says expert Daniele Carnevale.
