Selection of an appropriate design and re-evaluation method

Most of the available engineering procedures deal with the seismic quah-fication of structures, systems and components. Examples of qualification procedures in relation to other external events can be taken fi-om the NPP engineering community. 

Suitable coefficients can be applied to the results to compensate for the level of conservatism associated with any calculation methods. An adequate validation of such coefficients should be provided.
