Rosetexwool  Insulation Refractory Co., Ltd.

Nuclear Power

Radiation- and high-temperature-resistant insulation for nuclear power — auxiliary piping, fire compartments, waste storage and valve seals using calcium silicate and ceramic fiber.

Nuclear power plants demand insulation that is both high-temperature capable and radiation tolerant, while meeting strict fire-safety codes. Material selection favors dense, stable products that keep their integrity under thermal and radioactive load, and ceramic-fiber seals that survive valve cycling without degradation.

Application Scenarios

Nuclear Power Application Scenarios

  • Reactor auxiliary piping — calcium silicate insulation withstands high temperature and radiation.
  • Plant fire compartments — calcium silicate fills high-strength fire divisions.
  • Radioactive waste storage containers — calcium silicate layers limit temperature rise of containment.
  • Reactor valve seals — ceramic fiber gaskets resist heat and radiation under cycling.
  • Nuclear equipment insulation — ceramic fiber on steam generators, main pumps and high-temp equipment.
  • Nuclear fire doors — ceramic fiber cores with excellent high-temperature performance.
