In this paper, the effect of seismic waves on the SCWR is studied. To reduce the complexity, only the vertical motion has been taken into consideration in the current work. The vertical seismic acceleration is represented by a sinusoidal curve. Furthermore, the effects of the sine wave and the degree of instability of the initial state of the system, which is reliant on the power-to-flow ratio at the core, the axial power distribution will be investigated. This work describes the preliminary results through the simplified models and the significant calculated outcomes. The primary objective of this study is to supply quantitative information useful for determining to determine the significant effects of seismic waves on the SCWR system using LPM. In order to meet the objective, the transient thermal-hydraulic in-house code is used after being modified to take into account external acceleration in addition to gravity
