Description

technical field [0001] The invention relates to the field of nuclear reactor engineering, in particular to a testing device for an optimized structure of an inlet channel of an intermediate heat exchanger. Background technique [0002] Due to its inherent safety and the ability to provide high-temperature heat sources, ultra-high temperature gas-cooled reactors are particularly suitable for hydrogen production, process heat applications, and combined cycles in addition to high-efficiency power generation, so that they can effectively reduce fossil energy consumption in the above processes and greenhouse gas emissions. The intermediate heat exchanger is the key equipment to realize the heat utilization and hydrogen production of the ultra-high temperature gas-cooled reactor. As the transfer hub of high-temperature heat source (950-1000℃) and the pressure boundary of the primary circuit, the intermediate heat exchanger needs to serve for a long time (hundreds of thousands of ...
