Pairing correlations play a major role in nuclear structure. In the present contribution, we would like to discuss the effect of pairing in nuclear reactions like particle emission, transfer, fusion. The Time-Dependent Hartree-Fock Bogolyubov (TDHFB) theory has been developed to incorporate pairing theory in a fully microscopic transport theory either fully or in the TDHF+BCS simplified version. Application of pairing theories to schematic one dimensional model has permit to clarify the advantages and drawbacks of these approaches [1]. More recently, an effort has been made by our group to systematically investigate how the pairing correlation influence the large amplitude collective motion [2, 3]. In particular, the non negligible effect of pairing correlations on low energy collective modes like the giant quadrupole resonance, will be discussed. When nuclei collide, we show that one and two particle transfer are considerably affected by initial pairing correlations in one of the collision partners. Some reactions of recent and future interest will be discussed.
