Abstract: In order to meet the hydrochemical control requirements of primary circuit hydrogenation passivation process during HFT, the water quality control methods adopted in chemical platform, thermal shutdown platform and primary heating and cooling stages of HPR1000 unit are briefly described, and the implementation results are analyzed. The control results show that the water quality indexes of the HPR1000 unit are controlled within the expected range during the implementation of hydrogenation passivation.

Key words: HPR1000, hydrogenation passivation, hydrochemical control
