Abstract Scope MYRRHA is a LBE cooled accelerator driven system, currently in its latest design phase at SCK•CEN. Chemistry control of the liquid metal coolant is of paramount importance for the development of LBE cooled systems such as MYRRHA. An integrated numerical code based on CFD and chemical reaction module is being developed for LBE at SCK•CEN. Such codes allow numerical simulations to complement experimental activities in the research programme on MYRRHA reactor safety and operability. Equilibrium conditions of the LBE chemistry is modelled based on Gibbs free energy minimization method which enables the calculations of complex multi-component/multi-phase chemical equilibria of non-ideal solutions. The required thermodynamical data have been gathered from literature and/or measured by the CCP team at SCK•CEN. In this presentation, relevant simulation examples will be given for the design support of oxygen control units, general impurity chemistry in the MYRRHA primary system, and corrosion modeling in wire-wrapped fuel assemblies.
