Thermal hydraulic instrumentation system of the HTR-10 Original Research Article

The 10 MW high temperature gas-cooled reactor—test module (HTR-10) has many different characteristics compared with the pressure water reactor (PWR), such as special fuel elements, core construction, helium coolant and so on. Thus, the design of thermal hydraulic instrumentation system of the HTR-10 is also different from that of a PWR. This paper describes the design criteria and system integrating method of thermal hydraulic instrumentation systems in details. The main thermal instrumentation and devices specially developed for the HTR-10 are also introduced.
