Reactor Coolant Pumps (RCP) Advanced Sealing Technology

In the case of a station blackout (SBO), reactor coolant pumps (RCP) stop, leading to the leakage of significant quantities of water through the seals (typically several cubic meters per hour for each pump). A new technology of RCP seals that can withstand high pressure and temperature profiles in case of SBO has been developed by Framatome, taking into account the high expectations from our customers and from Safety Authorities. This RCP seal aims at withstanding an extended SBO. This technology can be implemented on both operating RCPs and new RCPs for new-build projects.
