Description

technical field [0001] The invention relates to the field of reaction vessel research, in particular to a high-temperature and high-pressure reaction kettle suitable for a heat chamber irradiation environment and a test method. Background technique [0002] The coolant (take water as an example) in the pressurized water reactor pressure vessel is usually a high temperature and high pressure liquid. When the temperature of water exceeds a certain value, nucleate boiling occurs, and the resulting steam bubbles may cause damage to fuel assembly materials. In order to study the bubble temperature of nucleate boiling and its effect on fuel assembly materials, it is necessary to test the fuel assembly materials in a high temperature and high pressure water vapor environment under irradiation. Such tests are usually performed in hot chambers (shielded small rooms where highly radioactive tests and operations are performed). However, the sealing structure of common high-temperatur...
