Abstract:
In view of the importance of the reliable operation and convenience maintenance of the control rod actuator to the safety operation and economic effectiveness of the reactor,through analyzing the deficiency of the control rod actuator of Unit 1&2,the design improvement plan for the control rod actuator of Unit 3&4 is formulated,in which the calculation and test method are used to demonstrate the possibility of the improvement.This may provide the effective reliability of the control rod actuator of Unit 3&4 and lay the foundation for station operation economic index and enhance the market competitiveness.
