Stud tensioning systems

For almost 60 years, we have been offering stud tensioning systems for opening and closing reactor pressure vessels in different sizes and for different applications on the international nuclear market. In addition to the manufacture of new machines, we also carry out modernizations of stud tensioners already supplied in order to bring them up to the latest state of the art. Customer-specific solutions and continuous further development of our machines are a matter of course for our experts.

With our innovations, we provide a significant contribution to shortening downtimes during overhauls at NPPs. With the newest generation of stud tensioners, the time required to open and close the RPV during annual power plant overhauls could be decreased to less than four hours per operation. A resulting side effect is the fact that the dwell time of the operating personnel in the radiation-intensive area and thus the dose exposure are minimized.
