Abstract The initial power outputs Po of pulsars are not yet well known, but these seem to follow approximately a distribution law N(> Po) ∝ Po −n where 0.5 ≤ n ≤ 1.0. It seems likely that Po ≥ 1038 ergs/sec. With these assumptions, we estimate that the DUMAND detector can record ≥ 103 high-energy (> 4 TeV) neutrino events in a four-month period per Galactic supernova; (in our Galaxy, these are estimated to occur at the rate of about 8 per century.) Neutrinos from supernova shells in the Virgo supercluster would be marginally detectable (one very bright supernova per decade at about 20 Mpc) if N(> Po) ∝ Po −0.5, but undetectable if N(> Po) ∝ Po −1. The diffuse flux summed over distant extragalactic supernovae is likely to be well below the detection threshold.
