*Abstract : The discoveries of neutrino oscillations demonstrated that neutrinos have non-zero mass, which contradicts the picture of the Standard Model. This opens the door for the existence of heavy neutrinos at the TeV scale. I will present a summary of the searches of heavy neutrinos at the LHC from Run 1. These Run1 searches were mainly done in the event sample which contains two leptons, two jets and no missing transverse energy. I will also discuss the prospect of these analyses in Run 2.
