tic safety analysis, reflecting the experience gained, capabilities of computers and computer codes. The basic rules for performing deterministic safety analysis of all plant states are established in the relevant IAEA safety guide SSG-2 (Rev.1). Nevertheless, there are needs for further enhancements of the current practices in applications of the deterministic safety analysis. The paper discusses examples of the areas where such enhancements would be appropriate, based on numerous reviews of safety analysis reports for new nuclear projects. The areas for enhancement include harmonization of approaches for analyses of radiological consequences of reactor accidents and their integration with thermal-hydraulic analyses, demonstration of practical elimination of early or large radioactive releases, improvements in consistency between neutronic, thermalhydraulic, structural and radiological analyses, broader use of quantification of uncertainties, establishment of clear links between analysis of internal and external hazards and safety analysis of plant states, the use of CFD codes in licensing, integration of deterministic and probabilistic safety analysis, and performing safety analysis for novel reactor designs, in particular for small modular reactors. The reasons and main directions for the enhancements will be presented in the paper.
