The unit, which achieved first criticality on 27 July, will now undergo tests at 30%, 50% and 100% of its generating capacity before entering a full power demonstration operating assessment, CNNC said. During this assessment stage, the performance indicators of the unit will need to meet design standards and the relevant requirements of the power grid, which will indicate that the unit has achieved formal commercial operating conditions.
