    Abstract

    The objective of the project is to continue the development of the truly independent transient calculation system, which can be utilized by the safety authority and other end-users for safety analyses. Thermal hydraulics of reactor core has been the main development area in this project. 3D thermal hydraulics model based on the porous medium approach has been developed and applied in several applications. Internal coupling of TRAB-3D neutronics and SMABRE hydraulics, which offers new possibilities to model more demanding flow situations, has been developed and tested. Tools for the studying of modeling uncertainties have been developed and applied both in the plant scale and in fuel rod scale. Participation in international work groups and benchmark activities has provided crucial support for the development work.
