Silicon Carbide and Silicon Nitride Seal Faces for Nuclear Reactor Coolant PumpsAlundum, Alfrax Al2O3, Hexoloy® SiC, Noralide Si3N4and Norbide B4C materials are used in nuclear fuel sintering furnaces, reactor coolant pumps, and neutron absorbing pellets in control rods.
Saint-Gobain Performance Ceramics & Refractories has manufactured and supplied seal faces for nuclear reactor coolant pumps for over 20 years.
Seal faces require intricate designs and must be highly machined, ground and lapped in order to conform to very tight tolerances required in nuclear reactor coolant pumps.
Seal faces are available in three materials: sintered alpha silicon carbide, sintered silicon carbide with excess carbon, and hot pressed silicon nitride. -
FAQ
Seal faces for nuclear reactor coolant pumps can be manufactured with pressure-less sintered alpha silicon carbide, sintered alpha silicon carbide with excess carbon and hot pressed silicon nitride.
Seal faces for nuclear reactor coolant pumps must be highly engineered to meet the specific tolerances of the application. These must be machined according to intricate designs, ground and lapped.
Saint-Gobain Performance Ceramics & Refractories is ISO 9001 and ISO 14001 certified. In addition to conforming to end-use specifications, nuclear reactor customers typically require a comprehensive audit of key suppliers involved in the supply chain.
