Commissioning procedures of the 10 MW high temperature gas-cooled reactor-test module Original Research Article

The 10 MW high temperature gas-cooled reactor-test module (HTR-10) commissioning is divided into three stages (A, B and C) and includes 100 test items. The commissioning flow charts of all stages are described in this article. Stage A, the preliminary performance testing before the fuel loading, has been completed now. Hence, each system and componentʹs performance is confirmed. Stage B includes fuel loading, first criticality, physics and low power experiments. HTR-10 attained the first criticality on 21 December 2000, and the succeeding physics experiments have proven the reliability of the physics designs. The commissioning is ongoing, while it is expected to increase the power, generate electric power, incorporate into the grid and rise the power to RP (rated power) by the end of 2002.
