The phenomenological implications of a 17 keV mass neutrino coupled to the electron in the weak charged lepton current with a constant ~ 0.1 are analysed. The possible nature of the heavy neutrino and the related phenomenological, astrophysical and cosmological constraints on its properties and couplings are discussed. Transitions of (ν)e leading to a reduction by (1-2)% of the (ν)e fluxes from reactors and accelerators, independent of the source-detector distance and neutrino moment, are predicted to take place. In most cases the transitions of (ν)e are into (ν)τ which practically coincides with the heavy neutrino. The νμ can ``weigh'' 17 keV or more than 85 keV. The problem of the heavy neutrino decay modes is briefly discussed.
