The corrosion of a component in a water-guiding loop of a nuclear facility is
reduced. A protective layer is produced with a sol-gel process. Prior to the sol
application, water that wettens the component is removed from the conduction system
and the component is optionally dried in a separate step. After the sol-gel process
has been carried out, the conduction system is again filled with water. A liquid
sol film that is produced on the component is dried, especially by means of hot
air. A component in the primary system of a boiling water reactor can especially
be coated with a highly corrosion-resistant zirconium oxide protective layer according
to the sol-gel process.
