This standard is intended for use at light watercooled, land-based nuclear power plants and may be used for guidance) where appropriate, at other types of nuclear power plants. Earthquake instrumentation is specified for the site, structures, equipment and piping. The kind and number of instruments required depend on the safe shutdown earthquake maximum ground acceleration designated for the plant. This standard does not include the following: (a) Instrumentation to automatically shut down a nuclear power plant at a predetermined ground acceleration. (b) Instrumentation to specifically provide information which would increase knowledge and understanding of seismic design. The need for such instrumentation is the basis for ongoing research and development programs. (c) Methods of analysis of recorded data.
