| The work aims to develop a test platform to simulate the test conditions of high temperature gas cooled reactor under normal conditions, oxidation corrosion conditions and accident conditions and study the oxidation corrosion behavior and long-term thermal aging law of ceramic reactor internals. By analyzing the service environment characteristics of ceramic internals in high temperature gas cooled reactor (HTGR), the technical requirements for the development of the test platform were determined. The main components included oxygen flow controller, helium flow controller, gas storage tank, reaction gas flow controller, gas preheater, high temperature reactor, gas circulating pump, helium purifier, pure water tank, peristaltic pump, vacuum pump, exhaust cold hydrazine, on-line gas chromatograph and on-line dew point instrument. The test platform could accurately control the trace amount of O2 and H2O impurities mixed into the coolant helium, and study the effects of reaction time, temperature and other factors. It could also simulate the normal conditions of high temperature reactor and the accident conditions of steam generator heat transfer tube rupture and water inflow, and carry out continuous thermal aging test for more than 3 000 h. Conclusively, the test platform has excellent characteristics such as high precision, large size, high temperature resistance and long-term test. It can simulate complex and diverse working conditions and carry out thermal aging test research. |
