DESCRIPTION: The gauged B-L symmetry is one of the simplest extension of 
 standard model. In the conventional case\, addition of three singlet righ
 t handed neutrinos each transforming as -1 under the B-L symmetry renders
  it anomaly free. It  is  usually assumed that the B-L symmetry is spo
 ntaneously broken by a singlet scalar having two units of B-L charge\, re
 sulting in a natural implementation of Majorana seesaw mechanism for neut
 rinos. However\, as we discuss in this talk\, there is another simple\nano
 maly free solution which leads to Dirac neutrinos with naturally small ma
 sses. We discuss the phenomenological consequences of this scenario inclu
 ding an application to neutrino mixing with S_3 flavour symmetry\, the po
 ssibility of long-lived dark matter and the phenomenology of the Z' boson
