(ANSA) - BELGRADE, OCTOBER 17 - The construction of a second nuclear reactor at the Slovenian Krsko NPP, an old idea put back on the table by the Slovenian authorities last summer, is "not a wise decision" as the site is located at a "capable fault" where strong earthquakes might occur, professor Kurt Decker, an Austrian geologist at the University of Vienna, told ANSA. "Among all of the European nuclear power plants, the site of Krsko is the one with the highest seismicity and therefore highest seismic hazard," Decker added during an interview with ANSA, underlining that the plant is located "at the boundary between the Adriatic and the Pannonian Plate where plate collision results in a large number of active faults and, hence, a large number of earthquakes including strong ones." "From the seismotectonic point of view the site is anything but ideal: threats include significant seismic hazard and 'fault capability'," the potential rupture of the ground surface by the movement of an active fault during an earthquake, Decker said. According to International Atomic Energy Agency, "the existence of a capable fault at or close to the site of a new nuclear power plant is a site exclusion criterion and 'an alternative site shall be considered'," Decker recalled.
