PRINCIPLES ENSURING COMPREHENSIVE ACCOUNTING OF PROCESSES ASSOCIATED WITH ENGINEERED SAFETY BARRIERS’ EVOLUTION: ASSESSING RADIONUCLIDE SPREAD BEYOND SITE BOUNDARIES

The article discusses the principles and approaches applied in the safety assessment of facilities based on the example of a modern tool DESTRUCT being currently developed. The code takes into account a set of processes associated with the evolution of engineered barrier system and is designed to predict the release of radionuclides from the near field.

Keywords: radioactive waste storage facility, radioactive waste, disposal, decommissioning, design modeling, engineered safety barriers, evolution, migration, comprehensive safety analysis.
