Few words from the Director
ŠKODA JS, its people, and our predecessors stood at the birth of Czechoslovak nuclear power seventy years ago. Our generation builds on their work. We draw on their experience and knowledge gained during the construction of numerous nuclear power plants, and through our current projects we demonstrate the professional expertise developed over decades. We are, and will continue to be, a reliable manufacturer and supplier of a wide range of equipment for the nuclear industry, serving both domestic and international customers. Our people and their know-how are our greatest asset.
We operate in a field that is one of the pillars of modern energy and places exceptional demands on safety, quality, and expertise. These values form the foundation of the daily work of our employees, who, through their experience, knowledge, and responsible approach, ensure the high standard of our products and services.
The service of important components of VVER-type nuclear power plants has a long-standing tradition at ŠKODA JS. Thanks to our experience, practice and know-how we are a strong and reliable partner for our customers.
Our strong professional background and our wide range of often unique and specialized services – that is something that not everyone in the market can offer.
The future prosperity of ŠKODA JS requires that we not only focus on current events and projects, but also prepare ourselves well for what is yet to come.
