Expert analysis commissioned by Germany’s opposition Green Party, has questioned the safety of the Temelín nuclear power plant in the Czech Republic. The latest issue of the German weekly Der Spiegel reported on the matter. According to the magazine, the study cast doubt on the quality of welds between Temelín’s pressure vessel and the surrounding cooling system, arguing that their quality was not well-documented or that existing documentation contained mistakes. The matter has been raised before and Czech experts found no defects in construction. Germany’s environment minister, Peter Altmaier, according to the publication, also saw no reason to press for additional tests at the Czech plant, earning him criticism from opponents of nuclear energy in Germany.
