Why consider subseabed disposal of high-level nuclear waste

摘要

Large areas of the deep seabed warrant assessment as potential disposal sites for high-level radioactive waste because: (a) they are far from seismically and tectonically active lithosphcric plate bounda-ries;(b) they are far from active or young volcanos;(c) they contain thick layers very uniform fine-grained clays;(d) they are devoid of natural resources likely to be exploited in the forseeable future, (e) the georgic and oceanographic processes governing the deposition of sediments in such areas are well understood, and are remarkably insensitive to pest oceanography and climatic changes
