Performance Assessment and Modelling - Safety Requirements on Heat-generating Radioactive Waste - Ongoing Development Process of Regulations

摘要

The "Safety Criteria for the Disposal of Radioactive Waste in a Mine" as of 1983 have to be revised with respect to the present state of science and technology and to latest international recommendations. The preparation of a draft proposal submitted by GRS in January 2007 was intensively supported by BfS. Main features are the isolation of heat-generating radioactive waste in the isolating rock zone, demonstration of safety for approx. 1 million years, stepwise approach to repository development and realisation as well as continuous safety-related optimisation process. These features were confirmed in a workshop on safety requirements organised by BfS in March 2007. In addition, the GRS draft proposal was examined by BfS on behalf of BMU. Thus, scientific-technical comments and remarks on the proposal as well as recommendations on these safety requirements to be addressed in a legal regulation on "Safety Requirements" envisaged by BMU were given by BfS.
