Nuclear
Do you have the technical support and engineering expertise to ensure your reactor linings maintain compliance with nuclear industry regulations?
Saint-Gobain provides a range of products for the nuclear industry including dense and insulating bricks, setters and foams. Made from high-purity aluminas, zirconias, and dense and acid-resistant silicon carbide (Hexoloy® SiC), materials from Saint-Gobain ensure high purity, chemical inertness, resistance to HF, thermal shock or erosion resistance.
Nuclear fuel pellets (uranium oxide) are sintered at high temperatures in a reducing atmosphere. The sintering furnaces need to be lined with high-purity alumina refractories. Alundum® AH199B or Alfrax® 101 high-density alumina bricks are used for the hot face wall and Alundum® AN599 bubble alumina-based insulating fire bricks made from are used for the backup lining. Saint-Gobain engineers can deliver a complete refractory design for your furnace.
Zirconium oxide materials offer extreme temperature and thermal shock resistance for your core protection system. No one works harder to co-develop product and design solutions for your nuclear application than Saint-Gobain.
