Experimental Study on the Residual Heat Removal System in HTR-10

Abstract The 10MW high temperature gas-cooled reactor (HTR-10) is a modular pebble-bed type reactor, of which the inlet and outlet helium are 250 700 °C, respectively. It reached to its first criticality in December, 2000, operated for nearly twenty years successfully. Currently, HTR-10 only that can operate world. To verify natural circulation operating characteristics safety features passive residual heat removal system, series experimental studies have been performed under different operation conditions HTR-10, include performance tests system various power, ambient single loop run mode. According data collation result analysis, it shows meets design requirements.
