Abstract: The antineutrino and electron spectra associated with various nuclear fuels are calculated. While there are substantial differences between the spectra of different uranium and plutonium isotopes, the dependence on the energy and flux of the fission-inducing neutrons is very weak. The resulting spectra can be used for the calculation of the antineutrino and electron spectra of an arbitrary nuclear reactor at various stages of its refueling cycle. The sources of uncertainties in the spectrum are identified and analyzed in detail. The exposure time dependence of the spectrum is also discussed. The averaged cross sections of the inverse neutron $\ensuremath{\beta}$ decay, weak charged and neutral-current-induced deuteron disintegration, and the antineutrino-electron scattering are then evaluated using the resulting ${\overline{\ensuremath{\nu}}}_{e}$ spectra.RADIOACTIVITY, FISSION $^{235}\mathrm{U}$, $^{238}\mathrm{U}$, $^{239}\mathrm{Pu}$, $^{240}\mathrm{Pu}$, $^{241}\mathrm{Pu}$, antineutrino and electron spectra calculated. $\ensuremath{\sigma}$ for $\overline{\ensuremath{\nu}}$ induced reactions analyzed.
