Testing Procedures for Seismic Qualification of CANDU Nuclear Power Plants
1.1 This Standard defines the consideration and requirements for performing an acceptable seismic qualification test and presents the different test methods that may be used.
Note: Selected safety related systems are required to be seismically qualified. (See CSA Standard CAN3-N289.1.) Qualification may be by analysis or testing, or a combination thereof, depending on the nature and complexity of the equipment. CSA Standard CAN3-N289.3 specifies methods of qualification by analysis.
1.2 This Standard is intended to provide a basis for developing specifications for seismic qualification by testing, and to aid equipment purchasers, suppliers, and testing laboratories in selecting the appropriate test methods for performing a seismic qualification test.
1.3 This Standard presents several acceptable methods with the intent of permitting the user to make a judicious selection from among the various options. In making such a selection, the user of this Standard should choose those test methods which best reco gnize the characteristics of a particular piece of equipment. Note: It should be recognized that seismic qualification forms only a portion of the overall equipment qualification program. It is important that the qualification program for a component include consideration of all operational loadings (seismic, environmental, aging, thermal, and mechanical stresses, etc) for which the component must demonstrably meet its performance objectives
