ON THE SELECTION OF A METHOD ALLOWING TO EVALUATE THE SENSITIVITY OF A MODEL TO ITS PARAMETERS WITHIN THE SAFETY ASSESSMENT OF RW DISPOSAL FACILITIES

The paper proposes a methodology enabling the selection of a method for parameter sensitivity assessment during numerical model development and its parametrization. Sensitivity analysis is considered essential for uncertainty analysis, which is provided for under relevant international guidelines on the safety assessment of RW disposal facilities, as well as federal rules and regulations in the field of atomic energy use. The paper provides some case studies on the application of the proposed approach.

Keywords: radioactive waste, numerical model, uncertainty, sensitivity, safety assessment.
