Study on an Automated Seismic Analysis Program for Nuclear Power Plant Equipment

초록

Seismic qualification for seismic category I equipment of nuclear power plants is essential to verify their structural integrity as well as operability during and after an earthquake. In such cases where structural integrity alone can ensure the design-intended function(e.g. tanks, valves, heat exchangers, etc.), seismic qualification is performed by seismic analysis. This paper suggests the KESQUS(KEPCO E&C seismic qualification solution) program that can automatically perform seismic analysis to generate seismic qualification reports using python by changing only the key design factors, thereby reducing the time and cost required for seismic qualification. In addition, the program can manage major design parameter in a single CSV (comma separated values) file that is easy for repeated analyses; hence, the program can also be used to identify optimized design parameters for equipment.
