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.

[Keywords]nuclear power plant;control rod assembly(RCCA);wear defect

在CPR1000核電機(jī)組中,控制棒組件是反應(yīng)堆的重要組成部分,是快速控制反應(yīng)堆反應(yīng)性的手段,在正常運(yùn)行時(shí)用于調(diào)節(jié)反應(yīng)堆功率,在事故工況下快速引入負(fù)反應(yīng)性,使反應(yīng)堆緊急停堆,保證核安全。(剩余3403字)
