Phoenix is a model-based HRA methodology developed to support the HRA of Nuclear Power Plants (NPP). Since its development, Phoenix has been applied to several case studies to test methodological and practical aspects. This paper discusses future extensions of Phoenix concerning: i) its use with dynamic PRA tools, and ii) its application to digital control rooms. It also discusses Phoenix Performance Influencing Factor (PIFs) and potential applications for inspection processes.

Keywords: Human reliability analysis, Phoenix, Digital control rooms, Nuclear power plants, Inspection.
