Severe design problems have plagued the plant from start-up (i.e., control rod motors malfunctions, wrong connection of cables, failing emergency cooling system). The plant is directly sending radiological (tritium) and ‘classical’ wastes (up to 53 tons of different chemicals and salts through an outlet pipe every day) in to the Jihlava River which flow ultimately to the Danube. The river is so polluted that the plant has problems using its water for cooling towers and plans to move the outlet further downstream to intake cleaner water. Additional problems include: unusually high production of liquid rad-waste and strong suspicions that the plant negatively influences the weather in the region (abnormal decrease of precipitation). In the area of safety, Dukovany epitomizes negligence and recklessness in the area of nuclear safety. Problems include lack of safety devices (i.e., missing containment) as well as the wrong design of many other strategic parts (turbines endangering the reactor, low fire protection, weak emergency supply of electricity, high risk of reactor vessel embrittlement). The plant has a malfunctioning warning system and inadequate evacuation plans. In fact, the the state deputy officially admitted they have no money for it, serious lack of technical equipment and that the plan is based on unrealistic presumptions.
