Abstract

Abstract

The sludge deposited on the secondary side of stream generator（SG） tube sheet will become hard as the process of time,and it will degrade the tube.In order to lance the sludge directly and decrease the harm to the tube,a sort of SG sludge flexible lancing was researched.This paper describes the structure,principle,technology index and difficulty of the sludge flexible lancing.The application result shows that the lancing satisfies the flexible lancing requirement and ensures the cleanness of SG secondary side.
