A study of methods for including uncertainty in Seismic PSA [PDF]

open access: yes, 2018
This thesis reviews current methodologies for conducting seismic Probabilistic Risk Assessment (PSA) for nuclear power plants, focussing on methods allowing for uncer- tainties in PSA input data. The techniques used to characterise earthquake ground motion and component failure probabilities (fragilities) and their uncertainties are described, and the ...

An investigation into minichromosomal maintenance proteins (MCMs) for the diagnosis of prostate cancer, as a possible alternative to prostate specific antigen (PSA) [PDF]

open access: yes, 2005
The current strategy for the diagnosis of prostate cancer includes serum prostate specific antigen (PSA) measurement. There is however debate into its specificity and sensitivity, so new diagnostic markers are under investigation.

Methodology of seismic-response-correlation-coefficient calculation for seismic probabilistic safety assessment of multi-unit nuclear power plants

open access: yesNuclear Engineering and Technology, 2021
In 2011, an earthquake and subsequent tsunami hit the Fukushima Daiichi Nuclear Power Plant, causing simultaneous accidents in several reactors. This accident shows us that if there are several reactors on site, the seismic risk to multiple units is ...

Overview of the seismic probabilistic safety assessment applied to a nuclear installation located in a low seismicity zone

open access: yesBrazilian Journal of Radiation Sciences, 2021
Deterministic and probabilistic nuclear safety analysis methodologies have been developed and updated based on operational experience, investigation of past incidents or accidents, and analysis of postulated initiating events in order to maintain the ...

Seismic Ground Response Analysis of Input Earthquake Motion and Site Amplification Factor at KUET

open access: yesJournal of the Civil Engineering Forum, 2021
Ground motion is the movement of the earth's surface due to explosions or the propagation of seismic waves. In the seismic design process, ground response analysis evaluates the impact of local soil conditions during earthquake shaking.

A new empirical equation of shear wave velocity to predict the different peak surface accelerations for Jakarta city

open access: yesGeodesy and Geodynamics, 2020
Site condition and bedrock depth play important roles in the determination of peak surface acceleration (PSA) values by earthquake motions. The soil parameters of shear wave velocity (Vs) and standard penetration test-number (N) value for Jakarta city ...

On improving seismic risk and cost for nuclear energy facility based on multi-objective optimization considering seismic correlation

open access: yesEnergy Reports, 2022
Currently, the system, structure, and component (SSC) seismic design and seismic probabilistic safety assessment (SPSA) process for the nuclear energy facility are performed individually, thus seismic risk reduction and cost efficiency cannot be pursued.

Multi-unit Level 2 probabilistic safety assessment: Approaches and their application to a six-unit nuclear power plant site

open access: yesNuclear Engineering and Technology, 2018
The risk of multi-unit nuclear power plants (NPPs) at a site has received considerable critical attention recently. However, current probabilistic safety assessment (PSA) procedures and computer code do not support multi-unit PSA because the traditional ...

Development of an earthquake-induced landslide risk assessment approach for nuclear power plants

open access: yesNuclear Engineering and Technology, 2018
Despite recent advances in multi-hazard analysis, the complexity and inherent nature of such problems make quantification of the landslide effect in a probabilistic safety assessment (PSA) of NPPs challenging.
