RISK ASSESSMENT OF URANIUM MILL TAILINGS DISPOSAL BORŠT, AFFECTED BY A LANDSLIDE (2011)
Risk analysis tools were implemented during closing activities on radioactive mill tailings disposal Boršt, affected by a landslide. The probability of landsliding before and after remediation works was calculated and expressed through relaiability index β. Choosing between three possible variants of redeposition of radioactive waste material was presented by a decision tree. When the closing construction activities were completed, all possible outcomes were determined by event tree diagram based on influence diagram construction. The geological elements that can cause adverse impact on mill tailings were determined and selected by geognostic map. The tools are very useful and outcome is clearly understandable to all the clients in the remediation process.
