Single Stud Tensioners for Pressure Water (PWR) and Boiling Water Reactors (BWR)

In nuclear power plants, where in accordance to the reactor cover design a MST cannot be utilized because of the reactor cover design, NIS offer customized Single Stud Tensioner.

The newly developed quick connect Single Stud Tensioners in a lightweight design are superior over conventional systems in terms of handling and pace.

Also, for these Single Stud Tensioners, the priority is focused on safe handling, the ALARP principle, efficiency and economic. The available technical variants permit customized solutions depending on the local requirements, and fulfilling the NIS quality standards for a Single Stud Tensioner.

Example:

• Single stud tensioner with quick coupling system or reaction nut drive

• Up to 6 Single Stud Tensioners can be connected to one electrically operated central hydraulic unit.

• The Single Stud Tensioners are operated directly at a control console or manually controlled at the Single Stud Tensioner.

• Lightweight design, reduces the weight of a single tensioner by up to 40%.

• Utilization of an integrated stud elongation measuring facility, monitoring with infrared data transmission and recording of the measured values.
