Safety instrument test facility (FITY) is one of the high temperature and high pressure test facilities in CGN. It is designed to conduct tests on thermal-hydraulic of safety system and instruments under the similar condition of reactor severe accident. FITY uses lot of copper components to realize sealing and insulation of vessel. Varies of hot state tests revealed that copper components worked well during the test, however, electrochemical corrosion was found as well, making water quality get worse. This article introduces chemical composition, physical properties and electrochemical corrosion behavior of copper component used in FITY, then analyzes the cause of corrosion and summarizes the notice for electronic component design under high temperature and high pressure conditions.
