Aiming at the uncertainty problem of crack character and location of concrete outside the penstocks,the cracking area of concrete outside the penstocks of the Three Gorges Hydropower Station under designed load is obtained by using nonlinear 3D-FEM.

针对三峡压力管道外包混凝土裂缝性状和位置的不确定性问题，通过对三峡压力管道的三维非线性有限元分析，得出了在设计荷载作用下三峡压力管道外包混凝土开裂区域位置，并给出了管道混凝土可能的最大裂缝宽度值。

Aiming at the uncertainty problem of crack character and location of concrete outside the pen-stocks, the cracking area of concrete outside the penstocks of the Three Gorges Hydropower Station under designed load is obtained by using nonlinear 3D-FEM. And the likely maximum width of crack of penstock concrete is also worked out.

针对三峡压力管道外包混凝土裂缝性状和位置的不确定性问题，通过对三峡压力管道的三维非线性有限元分析，得出了在设计荷载作用下三峡压力管道外包混凝土开裂区域位置，并给出了管道混凝土可能的最大裂缝宽度值。

Flow Accelerated Corrosion is an important aging mechanism for water and water/steam piping made of carbon steel or low alloy steel in both nuclear power plants and fossil power plants. Accidents in Surry Unit 2 in USA and Mihama Unit 3 in Japan, caused by pipe rupture due to FAC, led to severe casualties. The experience, mechanism and countermeasures about the aging management of FAC in nuclear power plants are summarized in this paper.

管道流体加速腐蚀是核电厂和常规电厂碳钢或低合金钢材料汽水管道的一个重要的老化机理，历史上曾发生过美国萨里核电站2号机组和日本美滨核电站3号机组管道破裂等导致人员伤亡的严重事故；本文简要总结了核电厂管道流体加速腐蚀的经验教训、机理及其老化管理的一些方法和对策。

Wavelet packet decomposition can decompose high-frequency part of signal. In order to obtain the energy rate index of each node this paper advances apply wavelet packet decomposition method to node response of pipe. And then use statistics method to analysis the energy rate index indicator of various nodes in pipe. Results show this method not only can detect the locations of damage in pipe, but also can get a preliminary study for quantify the damage degree damage of pipe.
