b'TALENT PIPELINE: The observed general trend in the seismic response of the reactor, heat exchangers, Samyog Shrestha, student and the buildings was that the acceleration amplitudes decrease with increased at Purdue University embedment depths. It was also shown that embedding the reactor buildings has positive effects on nuclear power plants economics, such as decreasing the thickness of the structures and reducing shutdowns during operations as compared to surface siting. A one-step non-linear numerical modeling approach was proposed and demonstrated for soil-structure and fluid-structure interactions of deeply embedded small modular reactors. Sloshing of models was validated with the available experiment data from the literature. One structural model was generated, and four seismic scenarios were considered based on embedment and how the water is modeled. When considering the response in the embedded and surface-founded structure that has the water mass distributed on the pool walls and the base, both models have a peak response at a frequency shifted down from a significant structural modal response. This is reasonable given that the full model includes water mass added to this location in the pool wall. When considering the response in the embedded and surface-founded structure that has the water explicitly meshed, both models have a peak response near the soil natural frequency. These peaks are due to the inertial mass of the water interacting with the wall, thus showing the effects of explicit modeling of the fluid body.PUBLICATIONS:Kurt, E. G., and R.
