   • Modeling and conducting analyses of transient and emergency regimes for all operational states of VVER-440 and VVER-1000 units, including full implementation of the analyses included in the Chapter “Accident Analysis” of the Safety Justification Report (analysis of the state of the core, analysis of the behavior of the containment, determination of the source and composition of the radioactive discharge outside the containment, assessment of the radiological consequences for the population and the environment), in accordance with national and international standards and laws;
   • Analysis of transient and emergency regimes and justification of proposals for modernization and safety enhancement of nuclear power units;
   • Analysis of transient and emergency regimes and preparation of proposals for the purpose of extending the operational resource of nuclear power units;
   • Analyses of processes in the containment areas of NPPs in the event of severe accidents and preparation of tasks for the design of severe accident management systems for units with VVER-440 and VVER-1000;
   • Supporting analyses in the development of emergency instructions and manuals for the management of severe accidents;
   • Analysis of the radiological consequences of design basis and beyond design basis accidents, support in the preparation of emergency plans.
