Knowledge and assessment of impacts of aging on structures are essential to plant life extension analysis,especially performance to severe loadings such as loss-of-coolant-accidents or major seismic events. Plant life extension issues are of keen interest in countries (like the United States) which have a large,aging fleet of NPPs. This paper addresses the overlap and relationship of structure aging to severe loading performance,with particular emphasis on containment structures.展开更多

For it not only relates to the community＇s harmony but also to the whole social＇s stability. This paper summarized some experiences and practices from some typical foreign countries on their community endowment, such as the British community care model, the Japan＇s aged care at home, the PACE mode of United States, the Germany＇s long-term care services, the Australian＇s old-age community security. On the basis of a comparative analysis, this paper concluded some experience and enlightenment of serving the old in abroad urban community, this include： Give full play to the function and role of the community in the pension, take law as safeguard on the implementation of community endowment, professional services, government-led and multiple subject participation, provide comprehensive and diversified service, etc. Combined with China＇s national conditions, this paper puts forward some countermeasures and suggestions in the end to further perfect China＇s elderly community service.展开更多
