Thermal image measurement analysis of human response according to operating variables of seismic simulator

The purpose of this study is to verify the physical and mental responses of operators under a seismic situation at a nuclear power plant. For this, the amplitude value suitable for the use of a seismic simulator is derived. To prevent injuries and accidents that may occur in the experiment, safety was considered as a top priority. As a result, the limits of amplitude that can be safely tested were confirmed as Surge, 9; Sway, 7; Heave, 7. The amplitude values corresponding to the reactor tripping criterion of 0.1 g were Surge, 5; Sway, 3; Heave, 4. Sensitivity to vibration is large at 5 to 10 Hz in Heave. In addition, the sensitivity of a Surge and Sway was found to be larger at 2 Hz. This test used a frequency of 2.5 Hz for consistency of safety and experimental variable, and consequently, the results were consistent with the results of previous studies. This study is the basic step of the correlation study between the change in amplitude and thermal image data.
