Analysis of Seismic Soil‐Structure Interaction for a Nuclear Power Plant (HTR‐10)

Science and Technology of Nuclear Installations, Volume 2017, Issue 1, 2017., 2017
The response of nuclear power plants (NPPs) to seismic events is affected by soil‐structure interactions (SSI). In the present paper, a finite element (FE) model with transmitting boundaries is used to analyse the SSI effect on the response of NPP buildings subjected to vertically incident seismic excitation.

The Investigation of Nonavailability of Passive Safety Systems Effects on Small Break LOCA Sequence in AP1000 Using RELAP5 MOD 4.0

Science and Technology of Nuclear Installations, Volume 2016, Issue 1, 2016., 2016
The passive safety systems of AP1000 are designed to operate automatically at desired set‐points. However, the unavailability or failure to operate of any of the passive safety systems will change the accident sequence and may affect reactor safety. The analysis in this study is based on some hypothetical scenarios, in which the passive safety system ...
