Stress Corrosion Analysis of Steam Generator Tube of Nuclear Power Plant by Finite Elements Shuang Jiang1, Jun Cai1*, J.W.Zhang1, Y.D.Wang2 1School of Nuclear Science and Engineering, North China Electric Power University, Beijing, China 2State Key Laboratory of Metal Materials, Beijing University of Science and Technology, Beijing, China *Corresponding author: caijun@ncepu.edu.cn Keywords: stress corrosion, FE calculations, heat transfer tube, Nuclear Power Plant, steam generator Abstract.
The parameters of these materials are listed in Table 1[2,7].
The stress corrosion of a material occurs in the three essential conditions, (1) the material is sensitive itself to a stress corrosion, (2) a large tensile stress acting on the materials, (3)the chemical environment which can cause stress corrosion[9,10].
Because the HTTs are made of the materials susceptible to stress corrosion, the tube rupture often occurs.
Moreover, there also are a lot of ions in the secondary side water, which are corrosive to the tube materials more or less[3,11].

Bond strength of the materials and the safety factor is in Table 5.

Introduction Carbide and nitride compounds and corresponding solid solutions attract the attention as promising materials for optoelectronics, microwave, high temperature and high-energy electronics.
Aluminum nitride is one of the promising coating materials, because it is dielectric and has low dielectric loss tangent and a thermal expansion coefficient equal to that of silicon [1].

Abstract Formation processes and morphology of nanostructured glass ceramic materials containing finely dispersed lead sulfide crystalline phase has been studied by X-ray technique.
This allows to use such glass ceramic materials as saturable absorbers for passive Q-switching and mode locking of a variety of IR lasers [4,5].
