Couple Thermal-Hydraulics & Kinetics for PWR LOCA Study

[madhisoka]

Is it possible to couple a thermal hydraulics code with a kinetics one ? , main purpose is to study the behaviour of kinetics due to a LOCA or any other changes regarding the coolant/moderator flow " talking about a PWR " .

Yes, it is possible and even common. You can theoretically couple any transient T/H code to any transient neutron kinetics code. There have been many papers written coupling different codes together.

Your title mentions CFD and PARCS. PARCS has been coupled to many different T/H codes, including RELAP and TRACE.
CFD is a little harder because of the very long run-times. It takes a very long time to run a full-core CFD calculation, so running a coupled calculation with CFD would be very time consuming.
