Human reliability for design applications at a Swedish nuclear power plant

This paper presents work in progress on a project to develop a process for integrating human reliability analysis (HRA) into the design process used in nuclear power plant modernization and upgrade projects. Human factors, probabilistic risk, and human-system interface design experts were interviewed, resulting in six principles for the use of HRA in design. These principles are: (i) early implementation, (ii) tailored methods, (iii) scalable methods, (iv) better use of qualitative information, (v) HRA design criteria, and (vi) better HRA sensitivity to human-machine interface issues. Future efforts will center on adapting HRA techniques to meet these principles and implementing HRA as part of a plant upgrade process.
