Recirculation system RUV

Wet Winding Motor Reactor Coolant Pump: Customized RCP for Generation 3 Applications: Reactor coolant recirculation in third generation nuclear power stations CAP1400 demonstration plant by SNPTC is a Chinese independent developed advanced passive pressurized water reactor with an electric output of 1,400 MW per unit. SEC-KSB will provide RUVs for one unit. It has set up special project and service teams to work with the customer in RUV prototype development and qualification testing so as to ensure the schedule, safety and reliability of equipment. Ø Operational safety n Maximum safety due to completely forged pressure boundary n Hermetically sealed (leakage free, no mechanical seals) n Perfect rotor dynamic behavior Ø Integrity under upset conditions Motor cooling through thermosyphon effect Ø Flywheel High inertia flywheel to address coastdown requirements Ø Optimized thermal barrier Advanced cooling concept for homogeneous temperature distribution Ø Optimized hydraulics Well-proven design with very high hydraulic efficiency Ø Maximum overall efficiency Due to proven wet winding motor technology Ø Maintenance free design
