Operator’s initiatives are important to achieve high level safety under the new nuclear regulatory inspection program, which was developed based on experiences in the United States and its Reactor Oversight Process. In the United States the performance of nuclear power plants was significantly improved in 1990’s and it has been continuously maintained at a high level since then. Some improvements in the management systems with risk- informed decision-making process were identified as key success factors. Th...

Importance of Operators’ Initiatives under the New Nuclear Regulatory Inspection Program

Safety of existing nuclear power plants has been enhanced by reflecting lessons learned from the Fukushima Daiichi Accident. For nuclear new builds, safety can be further enhanced in more rational ways. Hitachi GE Nuclear Energy (HGNE) developed an ABWR design for the United Kingdom in which Fukushima lessons were reflected. Some additional safety improvements were identified and realized by using the results of full-scope probabilistic risk assessments. In addition, collaborating with GE Hitachi Nuclear En...
