Detector Drive System (DDS) ​

  • Configurable redundancy
  • Reduced detector change-out time ​
  • Fewer components ​
  • High cable drive efficiencies ​
  • Reduced radiation exposure ​
  • Accurate detector position feedback ​
  • Flexible installation arrangement ​
  • Constant torque on detector drive cable ​

Magnetic Ball Check Valve and Leak Detection System​

Triumph Mechanical Solutions also offers Mag-Iso valves which can be incorporated as an after-market addition to some DDS configurations or included as an à la carte offering for some DDS configurations of utilities considering a new installation(s).​

Magnetic Ball Check Valve:​

  • Prevents reactor coolant water, flowing into a compromised thimble, from entering the Detector Drive System
  • Reduces personnel radiation exposure​
  • Prevents loss of reactor coolant after a thimble failure​
  • Prevents costly clean-up​
  • Sized to fit any system​
  • All valves pre-tested and certified​
  • Stainless ball and body prevents corrosion​
  • No servicing or calibration required​
