We propose a new mechanism to generate a 17 keV pseudo-Dirac neutrino naturally without subscribing to the see-saw mechanism. The vL's combine with the only sterile neutrino of the model to form a Dirac neutrino at the one-loop level. Two-loop contributions generate small masses for vine and vμ, the mass squared difference and the mixing being of the right magnitude to solve the solar neutrino puzzle. The 17 keV neutrino decays very fast into the lighter neutrinos and a singlet-doublet majoron.
