Info

Our aim is the safe, reliable and long-term operation of our power plant. High availability and cost efficiency are achieved through mature technology, a prudent mode of operation and the collective expertise of our staff. While output and efficiency have undergone a steady increase over the years, safety has always been our topmost priority and will continue to remain so. We intend to show that electricity generation from nuclear power continues to be safe, environmentally friendly and cost efficient even under harsher competitive conditions. � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � � �
