Siler International Workshop, Rome June 18-19, 2013

The latest violent earthquakes that struck Japanese nuclear power plants (in particular Kashiwazaki-Kariwa in July 2007 and Fukushima in March 2011) renewed international focus on the structural strength of nuclear facilities. This has forced the nuclear engineering community to concentrate a significant research effort in the evaluation and mitigation of risks associated to earthquakes.
The SILER thematic workshop is open to the experience of correlated research areas.
Invited lectures on specific topics strictly related with the major research issues on the seismic protection of LFR and ADS systems, alternated with presentations on several topics of general interest, for which a call for abstracts was launched earlier this year.
The workshop has been open to all experts in seismic isolation (thus not only related to GEN IV reactors) in order to exchange experience.
