  We calculate neutrino-induced fission cross sections for selected nuclei with
Z=84-92. We show that these reactions populate the daughter nucleus at
excitation energies where shell effects are significantly washed out,
effectively reducing the fission barrier. If the r-process occurs in the
presence of a strong neutrino fluence, and electron neutrino average energies
are sufficiently high, perhaps as a result of matter-enhanced neutrino flavor
transformation, then neutrino-induced fission could lead to significant
alteration in the r-process flow in slow outflow scenarios.
