3.15/4.14 BASES The operability of the seismic monitoring instrumentation ensuren that sufficient capability is available to promptly determine the magni-l tude of a seismic event and evaluate the response of those features Important to safety. This capability is required to permit comparison of l
I the measured response to that used in the design basis for the plant.
' i The time-history recordings of the triaxial time-history j
accelerographs are done in the cable spreading room using a solid-state
{
necelerograph.
The data is then processed and the results of the-l response spectrum analysis can be evaluated following a' seismic event.
