How long is the lifespan of the coating in water-cooled reactors

Thread Content

Given the application context of nuclear-grade coatings in water-cooled reactors mentioned earlier, there are clear industry standards specifying the designed service life for such moisture-resistant, heat-conductive, and radiation-resistant coatings in water-cooled reactors. General design life: In accordance with the domestic standard NB/T 20133-2012 \"Specifications for Protective Coatings of Facilities and Equipment in Pressurized Water Reactor Nuclear Power Plants\", the conventional design life for such nuclear-grade organic protective coatings in water-cooled reactor applications is over 10 years; this also represents the general standard requirement for coatings on equipment in domestic nuclear power plants. Actual service performance: When epoxy/resin compounds containing benzene rings are used as the matrix, along with radiation-resistant fillers such as boron carbide and nano-CeO₂, and under conditions that comply with construction standards (sandblasting to Sa2.5 level and controlled temperature and humidity), the actual service life can reach over 10 years. The service life can be extended further for some domestically developed, optimized formulations.
