Comparison of FT-IR and NIR method for cable classification

There are about 50,000 cables in NPP. The number of the cables need to be environmentally qualified are 1,000 cables to 3,000 cables depending on the NPP respectively. Some EQ cables are environmentally qualified and the steam test reports prepared, but some other EQ cables are not environmentally qualified or not prepared steam test reports. Not qualified EQ cables need to be qualified by steam test; high temperature and high pressure with the same condition of DBAs. There are thousands of EQ cables in NPP but all the EQ cables don't have to be tested entirely. The steam tests can be carried out by the same types of cables. One type of cable is tested and demonstrated that the cable's capability for the duration of the installed life, all the same type of cables are qualified. Therefore, the classification the EQ cables is very important to carry out the steam test effectively. Also cable classification method selection is important, too. I tried two kinds of methods to classify the Wolsong Unit 1 EQ cables, Near InfraRed (NIR) spectroscopy and Fourier Transform InfraRed (FT-IR) spectroscopy. In case of old NPPs, lots of cables are missing their material information or have the wrong material information. The two methods are capable of searching for the material information of the cable. Briefly, the purpose FT-IR and NIR scanning is to find out their material information and classification of the EQ cables
