1. Scope

1.1

This Standard applies to those structures and components in CANDU nuclear power plants which require seismic qualification by analytical methods (see CSA Standard CAN3-N289.1, General Requirements for Seismic Qualification of CANDU Nuclear Power Plants). ,, 1.2

This Standard specifies the requirements, criteria, and methods for: (a) Determining the DBE or SDE ground response spectra and ground motion time-histories from the seismic ground motion parameters obtained from CSA Standard CAN3-N289.2, Ground Motion Determination for Seismic Qualification of CANDU Nuclear Power Plants; (b) Performing acceptable seismic analyses, including the effects of the foundation medium; (c) Establishing design criteria for structures, components, and supports that require seismic qualification.
