Analytical Estimation of Structural Integrity for a Thermocouple in Nuclear Power Plant
Thermocouples used for temperature measurement in nuclear power plants should meet the seismic qualification regulations of -IEEE Std 323 and 344 so as to withstand big vibrations such as earthquakes. In this paper, we establish a model for the estimation of the structural integrity of the thermocouples that are used in nuclear reactor building models. We then review the need for seismic measure using modal analysis and the boundary condition. If the natural frequency is less than 33 Hz for the installation environment, response spectrum analysis was carried out taking into consideration the weight of this interpretation and that of the seismic load models in the input response curves (Floor Response Spectra) OBE (Operation Base Earthquake), and SSE (Safe Shutdown Earthquake). Finally, analytical estimation of the structural integrity of a thermocouple is performed by making a comparison of the maximum stress and the allowable stress.
