We present our calculations of the thermal neutrino radiation that accompanies the explosion of a minimum-mass neutron star. In this case, the neutrino luminosity is lower than the luminosity during a supernova explosion approximately by five orders of magnitude, while the energy carried away by neutrinos is low compared to the explosion energy. We also show that the energy losses through neutrinos do not hinder the envelope heating and the cumulation of the shock during its breakout and the acceleration of the outer part of the envelope to ultrarelativistic speeds.
