CFD SOFTWARE SIMULATIONS FOR THE REACTOR SAFETY IN NUCLEAR PLANTS
Safety in nuclear installations is of the highest priority in their exploitation lifetime, maintenance and decommissioning. A number of accidents with large consequences happened and this requires more scientific and engineering measures to be taken. In the years, nuclear safety “elaborated” tools in help of safety assessment and methods like PSA. Thermal hydraulic analyses are main tool in safety justification, providing safety procedures and new systems design. Apart from the so called “international practice” in nuclear safety number of initiating events and phenomena are identified as requiring different and more science substantiated methods and tools for analyses. Computational fluid dynamics is identified as suitable tool available and the only one that can give reliable solution of safety aspects regarding three-dimensional processes. The presented idea is an example of application of CFD code and specific problems in assessment of FloEFD  to be in use in nuclear safety field.
