May 22, 2016 · The Chubu Electric Power’s Hamaoka nuclear power plant in Omaezaki city, Shizuoka Prefecture, on the Pacific coast of central Japan, is situated directly above the interplate megathrust between the subducting Philippine Sea plate and the overriding lithosphere of …

Tokai Earthquake, Hamaoka Nuclear Power Station has adopted seismic design since the time of initial construction, allowing a conservative margin.

Oct 1, 2013 · In the seismic design of the Hamaoka nuclear power station, the soil nonlinearity was evaluated by the G – γ relation as shown in Fig. 12 (right). The stiffness reduction ratio ( G / G0) for the evaluated maximum strain is about 0.7.

[email protected] Abstract. The Suruga Bay earthquake in 2009 attacked the Hamaoka nuclear power station and stopped the operati. n. The maximum acceleration 4.38m/s2 at the foundation of the reactor building of No.5 unit was fo.

Oct 10, 2012 · The methods for judgement on the safe continuation of operation can be developed on the basis of the design information. The results of the seismic probabilistic safety analysis (seismic PSA) or margin assessment provide useful …

Therefore, for the assessment of seismic safety, it is necessary to consider the spatial variation of ground motion according to location. In this study, the spatial variation of ground motion was investigated using the earthquake records at the Hamaoka Nuclear Power Plant in Japan.

Jan 24, 2025 · We compared the earthquake vibration using seismic damage indicating parameters from a point of view called the influence on facilities here and considered conservatism of design basis earthquake ground motion applied in Hamaoka Nuclear Power Plant. (author) 580 p. 5 refs., 19 figs., 4 tabs.

Oct 1, 2013 · The Suruga Bay earthquake in 2009 attacked the Hamaoka nuclear power station and stopped the operation. The maximum acceleration 4.38 m/s 2 at the foundation of the reactor building of No. 5 unit was four times larger than that of No. 1 unit.

Probabilistic Seismic Hazard Analysis (PSHA) has been widely used for establishing seismic design spectra. In seismic design and analysis of Nuclear Power Plants (NPPs), the PSHA procedure may be required in generating input earthquakes such as Design Basis Earthquake (DBE) and Review Level Earthquake (RLE).

This paper presents an application of a proposed scenario earthquake-based approach for nuclear power plant (NPP) seismic probabilistic risk assessment (SPRA) and compares it to traditional SPRA.
