Abstract

Abstract

Finite element method is used in the reliability analysis on the quantitative detection of ECT （eddy current test）, and based on the calculation and analysis of of the tube signals in nuclear power plants, the quantitative excursion of tube defects and qualitative relations under different depth and width conditions are obtained, which proved that reliability analysis is more practical when the width of the tube defects is very small, and the efficiency and precision of ECT can be improved.
