Portable Seismic Acquistion System (Psas) For Pavement Masw

15th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2002
A seismic method (e.g., surface- or body-wave method) has been often used in pavement engineering to evaluate such critical constructional parameters as the E-modulus and Poisson’s ratio. Conventional method usually uses one or two-channel recording device (e.g., dynamic signal analyzer) for data acquisition whose cost is by no means trivial.

Seismic capacity evaluation of a group of vertical U-tube heat exchanger with support frames for seismic PSA

Nuclear Engineering and Design, 2005
Abstract This paper presents an evaluation of seismic capacity of a group of vertical U-tube type heat exchangers (HXs) with support frames to contribute to refinement of seismic capacity data for seismic Probabilistic Safety Assessment (PSA) in Japan. According to usual practice of seismic PSAs, capacity of component is represented as a log-normally

Developing a Seismic PSA Model with RiskSpectrum

2008
Seismic probabilistic safety analysis (PSA) is a tool for the assessment of risk to which complex technical systems such as nuclear power plants and their environment are exposed due to earthquakes. It has proven to be very useful tool for identifying weak points in plant’ s response to seismic events and quantifying the risk associated with them.

Development of systems reliability analysis code SECOM-2 for seismic PSA

Reliability Engineering & System Safety, 1998
Abstract An integrated code system SECOM-2, developed at the Japan Atomic Energy Research Institute (JAERI), has the following functions for systems reliability analysis in seismic probabilistic safety assessments (PSAs): (1) calculation of component failure probability, (2) extraction of minimal cut sets (MCSs) from a given fault tree (FT), (3 ...

Seismic PSA Studies conducted for Japan’s Light Water Reactors

2004
We have been developing analysis models for Seismic Probabilistic Safety Assessment (SPSA) of light water reactors, as one of the tools for assessing overall seismic safety of the domestic light water Nuclear Power Plants, since 1994.

Parallel System Architecture (PSA): An efficient approach for automatic recognition of volcano-seismic events

Journal of Volcanology and Geothermal Research, 2014
Abstract Automatic recognition of volcano-seismic events is becoming one of the most demanded features in the early warning area at continuous monitoring facilities. While human-driven cataloguing is time-consuming and often an unreliable task, an appropriate machine framework allows expert technicians to focus only on result analysis and decision ...

The use of the uniform risk spectra in the seismic PSA for a PWR power station

Nuclear Engineering and Design, 1995
Abstract This paper describes a simple method for incorporating the effects of the uniform risk spectra (URS) in the seismic probabilistic safety assessment (PSA) for a pressurized water reactor (PWR) power station. The “traditional” fragility parameters for a range of critical equipment items in a PWR power station on two typical UK sites are ...

A proposal for safety factor estimation in seismic PSA of structure by stochastic FEM technique

Nuclear Engineering and Design, 1994
Abstract The study of safety factor estimation in seismic probabilistic safety assessment has been a focus of researchers' interest for some time. Most of the papers dealt with the safety factor estimation by means of experimental knowledge or numerical analysis such as the Monte Carlo technique.
