Different lifecycle phases of a nuclear power plant present new human-technology- organization challenges to regulators and licensees. Organizational processes and practices that have evolved in one phase of development might be dysfunctional for the next phase, and the definition of “good safety culture” in practice might be unclear.
The objective of the SafePhase study is to improve the understanding of safety culture challenges facing regulators and power companies in different phases of large-scale nuclear power projects. The study utilized relevant literature and international experience on challenges in design, construction, installation and commissioning phases. Background information was provided by the interviews conducted at the Swedish Radiation Safety Authority. Some experiences concerning decommissioning were also reviewed, although this was beyond the scope of the study.
