Temelin NPP Not in Jeopardy by the Earthquake in Austria

All seismologic stations within Temelin monitoring network recorded this Tuesday, 11th July 2000, at 0450 hours local time the main tremor caused by the earthquake in Lower Austria near the village Ebreichsdorf, some 25 kilometers from Vienna. According to the analysis performed by the Institute of Physics of the Earth at the Masaryk's University in Brno, the maximal value of ground shifting at the locality of Temelin NPP was 13 micrometers for the prevailing frequency of 4Hz.

 

All seismologic stations within Temelin monitoring network recorded this Tuesday, 11th July 2000, at 0450 hours local time the main tremor caused by the earthquake in Lower Austria near the village Ebreichsdorf, some 25 kilometers from Vienna. According to the analysis performed by the Institute of Physics of the Earth at the Masaryk's University in Brno, the maximal value of ground shifting at the locality of Temelin NPP was 13 micrometers for the prevailing frequency of 4Hz. The maximal value of ground acceleration was on the level of 0.08 % of the Earth's acceleration due to gravity. "The measured level is deep in the safety zone, since Temelin NPP has been designed as a seismic resistant structure for acceleration up to 10 % of the Earth's acceleration due to gravity," states RNDr. Jan Svancara, CSc., Director of the Institute of Physics of the Earth, in his report containing measurement results.

"The tremors caused by the earthquake in Lower Austria were 125-times lower rather than those for which the NPP has been designed. No problems occurred in NPP objects due to tremors," added Ing. Milan Nebesar, NPP press spokesman.
