Synopsis:

The course extends theoretical knowledge from the course Thermohydraulics of nuclear reactors and different thermohydraulics courses and shows its practical application for design of nuclear reactors. Students come to know more about flow and heat transfer in the fuel bundles and different methods of thermohydraulic design of reactor core. In details are explained CFD solution, subchannel analysis and use of system codes for these purposes. Coupling of the mentioned methods and coupling with different calculations are explained too. Theoretical lectures are completed with exercises during which students practice theory on practical tasks which are solved by SW codes: CFD ANSYS group, ALTHAMC12, COBRA SFS and RELAP.

Requirements:
