A number of countries within Europe are developing or giving consideration to the development of geological disposal facilities for the disposal of high level radioactive waste. The safety authorities in these countries are interested in exploring the possibility of a harmonised approach to the demonstration of safety of such facilities and the regulatory review of documentation providing such demonstration. As such and with technical support organisations and international bodies they have initiated a pilot study on how these elements should be presented in a safety case, for, inter alia, regulatory review and approval. It is envisaged that such a study will cover assessment of the site and engineering, impact assessment and assessment of the management systems ensuring quality and will be compatible with internationally agreed safety standards, guidance and recommendations. It is foreseen that the safety case will evolve and mature as the project develops and this aspect has been considered within the pilot study, together with regulatory review and decision-making at discrete milestones associated with the disposal facility development. The study is focussed on regulatory expectations for the different milestones and addresses uncertainty management. The paper present the work carried out to date and the views for future work.
