The Development of Diagnostic System for Testing Air-Operated Valves

Air-operated valve is one of principal valves that are using to control fluid flow in nuclear power plants. A period diagnosis lot safety of power plants is necessary. But there are many difficulties such as economic loss caused by income of high cost devices and a matter hard to deal with users. In this study, we developed the diagnostic system that users of power plants are easy to handle. The diagnostic system is composed of database module, diagnosis test module and evaluation module.
