PSA level 2 analysis for Cernavoda NPP

For CANDU type plant Severe Accident is defined as loss of core structural integrity and severe core melts occurrence. To analyse the accident progression means to track the progression of the accident from the onset of core melt until one is assured that no additional release of radionuclides from the containment will occur. Analysis of the physical progression of an accident using deterministic models is performed to support the following activities: level 1 success criteria evaluation, event timing determination, sensitivity studies to support containment event trees (CET) development and quantification, input preparation to source term analysis.
