According to the regulatory requirements for seismic resistance design and seismic safety assessment of nuclear power plants (NPP), seismic resistance of NPP equipment, piping and their support structures is justified by calculating, experimental methods or their combination taking into account current regulations and standards. Therefore, the necessity to perform seismic resistance calculation of NPP components require to choose a regulatory document in accordance with which these calculations should be performed. In relation to thermomechanical equipment and piping, this issue is trivial because for many years, the design assessment of seismic resistance for these components is performed in accordance with the standards for strength calculations of NPP equipment and piping. At the same time, solving the issue of correct choice of regulatory documents and approaches to the seismic resistance assessment of steel support structures of NPP equipment and piping causes some difficulties. The article presents the developed general principles of seismic resistance assessment for steel support structures of NPP equipment and piping in accordance with up-to-date regulatory requirements and international experience, which are successfully implemented in practice of the operating organization for seismic safety assessment of NPP units. The article is part of a series of publications in the Nuclear and Radiation Safety Journal devoted to considering various aspects of the practical application of regulatory requirements for the seismic resistance assessment of NPP components.
