Abstract
Assuring a high level of safety is a pre-requisite for the development and utilization of nuclear technology. The most fundamental approach for nuclear power plant (NPP) safety is “defence in depth (DiD),” which is a combination of multiple physical barriers and multiple (generally 5) levels of protection, with the aim of accident prevention and mitigation. NPPs around the world have shown excellent safety records for over 14,500 cumulative reactor years, compared with other electricity sources, by properly implementing DiD. However, the occurrence and severe consequences of the Fukushima accident have provoked controversy on the completeness of the DiD concept. There have been active discussions on DiD with respect to the Fukushima accident. A general consensus has been arrived that the concept of DiD is still valid but its implementation was incomplete for the Fukushima NPP. Had DiD been properly implemented during the design, construction and operation, much better provisioning against the extreme earthquake and tsunami would have been available and the accident consequences would not have been so disastrous.
