Abstract:

The effects of high-energy pipe whipping after rupturing are very important in an AP1000 nuclear power plant's conventional island and restraints of pipe whipping should be considered in the design. It is the first time in the country when reinforced concrete shear walls are used as restraint services. In this paper, the behaviors of walls and restraint services subjected to pipe whipping are analyzed through static and dynamic methods in the finite element software (ABAQUS), in which all kinds of nonlinearities are considered. In addition, a test study on the restraint of pipe whipping is conducted. The results show that the wall and the restraint service can prevent pipe whipping effectively under the design load, and anchor plates arranged around the wall opening can improve the local concrete compression performance of concrete to reduce the damage of concrete. Meanwhile, the study also provides the valuable reference for wall designing to prevent from pipe whipping.
