Abstract: It is an important work outrage of PWRNPPs to install/dismantle the blocking board in the first side water chamber ofsteam generator, which is of higher radiation risk. The related work is introduced. Practices for collective dose reduction, such as analyzing radiation risk, optimizing staffing, strengthening simulation training and implementing experience feedback, are reviewed. It is expected to learn lessons, and provide improvement suggestions for other units to carry out the same work in the future.

Key words: CPR 1000 Nuclear Power Unit, Steam Generator, Blocking board, Radiation Protection
