Content: Severe core melt accident is the major source of public risks from nuclear power. In this talk, the speaker will present the development and application of a Risk Oriented Accident Analysis framework (ROAAM+) to assessment of severe accident mitigation strategy effectiveness in Nordic type boiling water reactors (BWRs). The assessment of effectiveness of the accident mitigation strategy requires an integrated deterministic-probabilistic safety analysis (IDPSA) approach.

In ROAAM+ framework all stages of the accident progression are simulated using a set of models coupled through initial and boundary conditions in a risk assessment framework. The analysis starts from plant damage states determined in PSA Level-1 and follows time dependent accident scenarios of core degradation, vessel failure, melt release, steam explosion and debris bed formation and coolability.

In order to achieve computational efficiency sufficient for extensive sensitivity, uncertainty, and risk analysis, the surrogate modeling approach is used. In the development of simplified but computationally efficient surrogate models (SM), we employ databases of solutions obtained by detailed but computationally expensive full models (FM).
