This paper reviews current status of the unified approach known as integrated safetyassessment (ISA), as well as the associated SCAIS (simulation codes system for ISA) computerplatform. These constitute a proposal, which is the result of collaborative actionamong the Nuclear Safety Council (CSN), University of Madrid (UPM), and NFQ SolutionsS.L, aiming to allow independent regulatory verification of industry quantitative riskassessments. The content elaborates on discussions of the classical treatment of time inconventional probabilistic safety assessment (PSA) sequences and states importantconclusions that can be used to avoid systematic and unacceptable underestimation of thefailure exceedance frequencies. The unified ISA method meets this challenge by couplingdeterministic and probabilistic mutual influences. The feasibility of the approach is illustratedwith some examples of its application to a real size plant.
