Thus, requirements additional to those specified in this Standard may be impose

36、 by the Technical Committee.May 2010Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the

37、Standard to judge its suitability for their particular purpose.(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not ne

38、cessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.(4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to

39、the appropriate committee.

42、ds AssociationGround motion determination for seismicqualification of nuclear powerplantsMay 2010 1N289.2-10Ground motion determination for seismic qualification of nuclear powerplants0IntroductionDetermination of ground shaking hazard involves the following:(a)geological and seismological investiga

43、tions performed for site, site vicinity, and region;(b) development of seismic source models;(c) evaluation of seismogenic potential;(d) development of earthquake recurrence models;(e) evaluation of maximum potential earthquake;(f) development or adoption of ground motion prediction equations;(g) ex

44、ecution of a probabilistic seismic hazard assessment;(h) generation of uniform hazard response spectra;(i) development of scenario earthquakes;(j) evaluation of seismic hazard uncertainties; and(k) evaluation of seismically induced phenomena (tsunami, seiche, volcanism, slope instability, surface fa

45、ults, surface instability, and dam failures) to be accommodated by nuclear power plant siting and design.Notes: (1) Figure1 is a flowchart outlining the ground motion determination process and the investigation of seismically induced phenomena.(2) In this edition of the Standard, a procedure for the

46、 determination of seismic ground motion is described that is generally compatible with procedures described in similar guides (e.g., IAEA Safety Standards Series No. NS-G-3.3) and codes of other countries. The recommended procedures described in AnnexA may be replaced by other procedures, provided t

47、hey are based on an equivalent interpretation of the seismotectonics of the region and provided they include sufficient information to estimate the uncertainties associated with the derived seismic ground motion.1Scope1.1This Standard describes the investigations required to obtain the seismological

48、 and geological information necessary to determine, for a proposed or existing nuclear power plant site, the seismic ground motion that will be used in seismic qualification of safety-related plant structures and systems, and the potential for seismically induced phenomena that can have a direct or

49、indirect effect on plant safety or operation.Note: CSA N289.2 establishes the basis for a family of seismic hazard results that can be used as input to CSA N289.3. CSAN289.2 does not specify (a) ground motion parameters to be used in design;(b) probability level; or (c) degree of confidence to be achieved.1.2This Standard was developed for the determination of ground motions for regions of low to moderate seismic hazard, comparable to the levels near Canadas existing nuclear power plants. In regions of higher seismic hazard, the assessment of strong ear
