Safety related equipment installed in Korean Nuclear Power Plants are required to perform a safety function during and after a seismic event, lb accomplish this safety function, they must be seismically qualified in accordance with the intent and requirements of the USNRC Reg. Guide 1.100 Rev. 02 and IEEE Std. 344-1987. This paper defines and summarizes acceptable criteria and procedures, based on the Korean experience, for seismic qualification of purchased equipment to be installed in a nuclear power plant. As such the paper is intended to be a concise reference by equipment designers, architectual engineering company and plant owners in uniform implementation of commitments to nuclear regulatory agencies such as the USNRC or Korea Institute of Nuclear Safety (KINS) relating to adequacy of seismic Category I equipment. Thus, the paper provides the methodologies which can be used for qualifying equipment for safety related service in Nuclear Power Plants in a cost effective manner.
