Production

We are a strategic, experienced and reliable partner in the field of component and equipment production for VVER nuclear technology (PWR pressurized water reactors) as well as the western-type BWR reactors (boiling water reactors).

Production

We have been operating in the VVER nuclear technology market for almost 40 years. During this time, we have produced 21 complete VVER 440/V-213 type reactors and three VVER 1000/V-320 type reactors, including the control rod drives. For more than a quarter of a century, we have also been active in the market of PWR and BWR-type nuclear power plants.

Our entry to this market required the acquisition of special certifications, such as ISO, ASME, DIN, CEFRI and others. We have gradually worked our way up to the role of a qualified supplier of nuclear equipment for the main contractors and operators of nuclear power plants in Western Europe, the U.S.A. and the Far East. We produce equipment either based on the customer's documentation or we can develop and manufacture new equipment based on the initial design.

ŠKODA JS responded to the changes in demand for complete VVER type reactors in the 1990s by developing a new production program focused on nuclear fuel handling. This is currently one of the key segments of our production division.

In the early 1990s, ŠKODA JS further focused on the modernization and lifetime extension of existing components as well as on the supply of spare parts. We developed and produce storage racks of our own design. A product category offering good prospects is storage casks for various fuel types and nuclear waste, developed in-house, licensed and supplied by us.

Our key product is modernized control rod drives, which we produce and supply for various types of nuclear power plant reactors as well as research nuclear reactors, including the I&C system. Thanks to our innovations, we have gradually managed to extend their design lifetime and met all the technical as well as legislative requirements for extended reliable operation of control rod drives in both standard and emergency modes.
