Effect of Radiation Exposure on Fibre Optic Cables

Popis výsledku v původním jazyce

The good experience with optical communication and its advantages in industrial applications have lead to introduction of optical communication technology into more conservative areas, such as the nuclear and aerospace industries. The number of optical cables in nuclear power plants has been increasing. Fiber optic cables are commonly used at nuclear power plants in I&C systems but they are usually used in mild environments. For example, the Czech nuclear power plant in Dukovany, a PWR type with four 440 MW units, has 1330 installed optical cables. All the optic cables are situated in mild environments, i.e. without radiation. Nevertheless, currently, the number of applications in harsh environments with radiation is increasing. Application of safety related fiber optic cables in harsh environments of nuclear power plants (NPPs) requires their qualification. The international standard for qualification IEEE 1682: Standard for Qualifying Fiber Optic Cables, Connections, and Optical Fiber Splices for use in Safety Systems in Nuclear Power Generating Stations – has existed since 2011. The presentation will describe all the experiments and bring explanation for this unexpected property.
