Mitigation of Tsunami Environmental Implications on Nuclear Facilities through Improvement of Seawall Design

The preservation of man and the environment is one of the most important principles to be taken into consideration when designing a nuclear project. Therefore, the first objective of environmental design is to mitigate the effects of natural disasters on nuclear facilities. The tsunami is one of the most important environmental threats to nuclear plants built on sea coast. Therefore, the aim of this research is to study the environmental design of the sea wall as the first line of defense against the tsunami. On the base that the sea wall that protects the nuclear plant should be considered as a part of nuclear facilities design.

This paper aims at studying criteria for seawalls design, history of sea defense design standards, and explaining the process of revision of design guidelines. A discussion of international approaches and their application to nuclear power plants is also provided.
