Reactor Coolant pump Shaft Seal Systems

A3209

The Reactor Coolant Pump (RCP) seal systems are subjected to extreme conditions, ranging from low pressures during start-up and shutdown phases to high pressures and temperatures under normal operating conditions. These systems play a key role in maintaining the integrity of the primary circuit pressure boundary, representing one of the most demanding applications.

For over 50 years, Framatome Jeumont has been designing and manufacturing RCPs, motors, and seal systems for the global nuclear market. Customer benefits include:

  • Enhanced safety: The PSDS ensures the sealing of the primary circuit in case of Station Blackout (SBO) or Extended Loss of AC Power (ELAP).
  • Design and manufacturing compliant with original requirements.
  • Leverage of extensive operational experience.
  • Equivalency certifications for originally supplied equipment.
  • Comprehensive and integrated services.
