Regulatory issues under discussion in the preparation of the Finnish safety regulations for spent fuel disposal

Finnish Centre for Radiation and Nuclear Safety is preparing a general safety regulation for spent fuel disposal. In the course of this rulemaking, several regulatory issues have emerged that are even internationally still under discussion. These include use of different safety indicators depending of the time period of interest, how to judge the suitability of a proposed disposal site and what is required for a safety assessment intended for demonstration of compliance with safety goals.
