Plant Annunciator의 내진에 대한 구조적 건전성 평가

초록

This paper presents a plant annunciator system model for this analysis. Seismic qualification analysis for plant annunciator system is carried out to confirm the structural integrity under the seismic conditions represented by required response spectra(RRS). For the analysis finite element method(FEM) is used. And mode combinations are adopted to obtain the reliability of the spectrum analysis. The analysis results shows that the plant amnunciator system is designed as a dynamically rigid assembly, without any resonance frequency blow 33Hz. The calculated stress of the plant annuciator system is much less than yield stress of used steel.
