Seismic Safety of Bridge Crane Steel Structures Operating in NPP
Journal Title: RECENT - Year 2011, Vol 12, Issue 32
Abstract
The seismic stability assessment of systems and equipment operating in Nuclear Power Plants (NPP) is a very important preventive precaution for ensuring their emergency safety. The actuality of this case study arises extremely after Fukushima NPP disaster, caused by the earthquake on 11 March 2011. Bridge cranes are a significant and integral part of the technological equipment, which affects the modern NPPs’ safety. The main aim of the present study is to propose an analytic-simulation approach for analysis of bridge crane steel structures dynamic behavior during earthquake impact as to evaluate mostly the sliding ability of crane traveling wheels on rail roads. Loads and harmful effects acting on the crane bridge steel structure caused by the sliding phenomenon are defined and analysed.
