Description
After Fukushima Nuclear Accident, some new safety concepts and new safety requirements are suggested and discussed among the nuclear industry and nuclear safety regulatory organizations all over the world. In this paper, new safety concepts and new safety requirements, such as “Design Extension Condition”, “enhance the application of Defense in Depth”, “independence between different levels of Defense in Depth”, “enhance the diversity design of safety features”, “safety level should be As High As Reasonable Achievable”, and “practically elimination of large release of radioactive materials” are discussed; and also it is stated in this paper that, with the consideration of “safety level should be As High As Reasonable Achievable”, deterministic and probabilistic methodologies should be used to identify the safety voluntaries in the design of NPPs, and reasonable practicable measures should be taken to minimize the consequence of residual risk, and to achieve the safety goal of practically elimination of large release of radioactive materials.
