Abstract
Neutrino reactions on nuclei play important roles for the dynamics of supernovae and their associated nucleosynthesis. This manuscript summarizes the current status in deriving the relevant cross sections for supernova neutrinos and briefly discusses a few recent advances in supernova simulations where these reactions play a role.

The later scenario has been favored for many years as the possible site for the astrophysical r-process, but recent supernova simulations indicate that the conditions in the neutrino-driven wind are probably only sufficient to support a weak r-process which contributes to the observed r-process abundances up to the barium mass region
Summary
Neutrinos are key-players for the supernova dynamics [1, 2]. During the collapse phase the main neutrino source is electron capture on nuclei [3, 4]. 2. Cross section models Supernova neutrinos of interest here have relatively low energies (up to a few 10’s of MeV).
