Development of nuclear grade cable aging assessment technology based on patent analysis
The use environment of various cables in nuclear power plants is special,and various technical means are needed to ensure their safe operation during the service of nuclear power units.If the use state of the cable can be reasonably evaluated and the cable life can be accurately predicted by means of evaluation,the cost can be saved on the premise of ensuring safety.In view of the domestic and foreign patent applications in the field of nuclear grade cable aging assessment in the past 30 years,the development status of this technology is analyzed from the aspects of annual distribution,regional distribution,main applicants and core patent technology of patent applications,and the existing problems are pointed out,so as to put forward suggestions for the development and technical research of related enterprises.
