适用范围：This International Standard specifies the requirements to be taken into consideration when designing a nuclear power plant in relation to seismic hazards.It specifies the data required and the way in which these data should be used in order to determine the earth motions to be taken as the design basis ground motion for design purposes.It does not specify, on the other hand, earthquake levels for other purposes, for example inspection level earthquakes or operating basis earthquakes, which in reality have no simple relationship to the DBE (see 2.2.18) and other seismic motions ; thus the specification and use of these other motions shall be agreed with national regulatory authorities.This International Standard specifies the way in which the proof of seismic design adequacy should be established and documented for the various parts of the plant (foundation material, buildings, systems and components); the instrumentation is also specified.The methods to be used for both probabilistic and deterministic methods for the determination of the DBE are covered in this International Standard and either method is acceptable. The detailed requirements in this International Standard are ap-plicable to sites in which the maximum potential ground motion is predicted to be equivalent to intensity MSK VII or above.This International Standard is entirely applicable when the DBE is greater than or equal to intensity VII on the MSK scale. When the DBE is less than intensity VII on the MSK scale, the struc-tural analysis (see clause 5 et seq.) could also be performed by using simpler rules which are outside the scope of this International Standard.
