For many decades, quantum many body methods have been applied successfully in describing the structure of atomic nuclei.  As the models have become more sophisticated, and the available computation resources more powerful, it is now possible to treat nuclear reactions on the same footing. In this work, a framework for modeling nuclear reactions within valence space shell model is presented, focusing on neutron on target reactions, specifically neutron on 20Ne and 36Ar. The framework is general enough to be used with any many body method, provided the method can produce all relevant spectroscopic amplitudes. The framework can also be extended to charge exchange reactions, and to include gamma channels. By treating reactions and structure in a consistent manner, a host of questions can be explored, for example: what is the range  of applicability of Hauser-Feshbach theory, which forms the foundation of compound nuclear reactions.
