  Simulations of nucleosynthesis in astrophysical environments are at the
intersection of nuclear physics reaction rate research and astrophysical
applications, for example in the area of galactic chemical evolution or
near-field cosmology. Unfortunately, at present the available yields for such
applications are based on heterogeneous assumptions between the various
contributing nuclear production sites, both in terms of modeling the
thermodynamic environment itself as well as the choice of specifc nuclear
reaction rates and compilations. On the other side, new nuclear reaction rate
determinations are often taking a long time to be included in astrophysical
applications. The NuGrid project addresses these issues by providing a set of
codes and a framework in which these codes interact. In this contribution we
describe the motivation, goals and first results of the NuGrid project. At the
core is a new and evolving post-processing nuclesoynthesis code (PPN) that can
follow quiescent and explosive nucleosynthesis following multi-zone 1D-stellar
evolution as well as multi-zone hydrodynamic input, including explosions. First
results are available in the areas of AGB and massive stars.
