The list indicating combinations of process conditions for operation of steel support structures of nuclear power plant equipment and piping and seismic hazards established in regulatory requirements is relatively extensive. It includes all possible cases of process conditions for operation of equipment and piping. Therefore, in assessing the seismic resistance of support structures, the question about potential optimization of the list with load combinations established by regulatory requirements arises. Such optimization can be performed after analyzing the impact of changes in the process conditions for operation of steel support structures of nuclear power plant equipment and piping on their seismic resistance. The article defines a list with parameters of process conditions for operation of support structures of nuclear power plant equipment and piping that affect their seismic resistance. The impact of changes in these parameters on the seismic resistance of support structures is studied. The article is part of the series of publications in the Nuclear and Radiation Safety Journal focusing on various aspects related to application of regulatory requirements for the assessment of seismic resistance of nuclear power plant components.
