A Computational Infrastructure for Nuclear Astrophysics has been developed to streamline the inclusion of the latest nuclear physics data in astrophysics simulations. The infrastructure consists of a platform-indepedent suite of codes that are freely vailable online at nucastrodata.org. The newest features of, and future plans for, this software suite are give in.

The observations of metal-poor stars with metallicity [Fe/H] 
have been extensively performed. The abundance patterns of these stars are well explained by supernova models with extensive material mixing and fallback onto the compact remnant. Nevertheless important deficiencies of odd elements (especially Sc and K) are present in most investigations. Recent simulations of core collapse supernovae showed that innermost ejecta undergo large amounts of neutrino flux and neutrino interactions with materials in these ejecta change electron fraction to 
. Nucleosynthesis in the proton-rich environments allows Sc and Zn (which are less produced in normal supernova models) to be enriched. Therefore, it is interesting to investigate the influence of a large variation of on explosive nucleosynthesis. We calculate nucleosynthesis with ranging from 0.48 to 0.58 in complete and incomplete Si burning layers in Pop III supernovae. We discuss the production of some important nuclei and compare the abundance patterns with those in observed extremely metal-poor stars.
