Simple spectroscopic program aiming at measuring Be and Li abundances in solar-type stars of 3 open clusters spanning the age range 0.1-4.5 Gyr. The goal is to further investigate the nature and evolution of mixing in the stellar interior of main sequence (MS) solar-type stars. If possible, preference should be given to the completion of all OBs available for the same target, in order to avoid the risk a posteriori of being unable to detect beryllium. Be aware of different constraints associated to the different targets, and (as pointed out by S.Brilliant) that airmass constraint (1.2) on NGC2516 is 'unfeasible' for specified exp.time - it should be considered slightly relaxed.
