According to the statistics of IEA (International Energy Agency), China has the strong dependency on the coal energy. However, the coal energy creates the highest level of CO2 emission among the energy resource. Since 2006, China became the most important CO2 emission country. In order to control the air polution and the CO2 emission, Chinese government is diversifying the energy resource for its economy. After Fukushima incident, Chinese government checked the safety of nuclear facility and suspended the new nuclear power plant construction. This governmental measures were similar to those of Germany. However, Chinese government resumed the new nuclear power plant construction while Germen government turn its nuclear policy into the shutdown. The important role of Chinese governmental nuclear companies is similar to the French situation of nuclear energy development by the Government-owned company. Like the French nuclear company which acquired its nuclear technology from Westinghouse, China introduced and learned the nuclear technology from USA (AP1000) and from France (EPR). Especially, French government and French nuclear company are willing to cooperate with China in the field of nuclear energy. French nuclear company, Areva expect that the over than 50% of potential nuclear energy development in the World will be created in China.

This study presents a structural safety analysis method for a plant annunciator panel under the seismic effect. Seismic qualification analysis for the nuclear plant annunciator panel is carried out to confirm the structural integrity and the results are represented by required response spectra. For the numerical analysis, finite element method is adopted. Mode combinations are also used to obtain the reliability of the spectrum analysis. The analysis results shows that the nuclear plant annunciator panel is designed as a dynamically rigid assembly, without any resonance frequency blow 33Hz. The calculated stress of the nuclear plant annunciator panel is much less than yield stress of used steel.
