Effective response spectra for the dynamic qualification of equipment and subsystems
Abstract
The objective of the Floor Response Spectra (FRS) -and its “raison d'être”- is to serve as a dynamic input for the qualification or design of equipment and subsystems in nuclear power plants. The achievement of this objective has been questioned in practice from different standpoints; it is generally agreed that the conservatism accumulated right through the seismic analysis process is excessive, particularly if the regulatory positions are rigorously followed; additional broadening of the peaks and enveloping of several FRS, in order to cover different equipment locations and equipment groups, introduces additional doses of conservatism.
