The ground motion attenuation relations have been proposed on an empirical basis and widely been used for ground motion prediction in convenient and efficient way. The accuracy of the predictions, however, is not so high given an earthquake magnitude and distance, the uncertainty of the relations has, say, 0.5 or more in a natural logarithmic standard deviation, which significantly governs the ...

The OECD is a unique forum where the governments of 33 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisati...

The Loviisa NPP went through an extensive severe accident management (SAM) programme during 1990's and early 2000's. Programme included a wide range of experimental and analytical studies and the selected SAM approach led to significant plant modifications. The SAM approach was developed and the SAM systems were designed to cope with the accidents starting from power operation states. More rece...

Intensive researches in seismology and earthquake engineering are ongoing in Korea since the mid 1990s.This paper summarizes recent R&D; results regarding the improvement of earthquake catalog, seismicityand tectonics, ground motion, and PSHA methodology. The effect of the R&D; results on the seismichazard was studied for the Ulchin NPP site. Results showed much improvement in the...
