Analysis and Measures of Wear and Tear of Control Rods in CPR1000 Nuclear Power Plant

Liu Jing-jing,Cao Meng,Zheng Hai-yang

[Abstract]The control rod assembly(RCCA) is an important part of the core of the CPR1000 nuclear power plant. With the operation of RCCA in the reactor, wear defects will occur. Through ultrasonic eddy current inspection of the control rod cladding wear and analysis of the wear causes, proposed measures and analysis and evaluation provide reference for the control rod management of CPR1000 nuclear power plant.
