We investigate the effects of intermittent strong jets from an ActiveGalactic Nuclei (AGN) of a massive galaxy in the core of a cool core galaxycluster, on the dynamics and metal distribution of the intra-cluster medium(ICM). We use a simple model for the metal distribution within the host galaxywhich includes metal injection via star formation. We carry out 2D axisymmetrichydrodynamic simulations of these systems. After having established a coolingflow, two light jets are injected in opposite directions with a range of(intermittent) active phases. We follow the time evolution of the system fromthe jets' active phases up to 3 Gyr. The general metallicity evolution for allour simulations is very similar on large-scales. The convective flows driven bythe jets advect gas and metals from the central galaxy to distances beyond 1.5Mpc within the cluster. Intermittent jets are able to distribute metals tograter radii. The metal injection has effects on the general metal abundancespresent in the ICM, the faster the metal replenishment time the higher themetal abundance. Although metallicity gradients in the very central regions ofcool core clusters are likely to be shaped by less-energetic phenomena, we findevidence in our simulations for metallicity gradients similar to those observedout to ~400 kpc radius. The metal distribution details of the central galaxyhave no effects on the dynamical evolution of the ICM metals.
