Abstract

For floating nuclear power plants (FNPP) operating at sea, the mechanical penetration assemblies (MPA) installed on FNPP are designed to withstand large wave-induced swing loads, so it puts forward higher requirements for the structural strength of MPA. Currently, the strength evaluation of MPA under swing load is still insufficient. A set of numerical simulation method for MPA is established, and the swing experiment is designed to verify the accuracy of the simulation results. The results show that the Mises stress of the MPA are far lower than the allowable stress of the material, and the structural strength is within the safe range; By comparing the relative error of the two data, the average error is 4.6 %, which is in line with the error threshold accepted in the engineering field. The effectiveness and accuracy of the numerical simulation method in predicting the behavior of MPA under swing loads are verified.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
