The ability to accurately model space background is a crucial requirement for significant progress in the field of observational nuclear gamma-ray astronomy. An Advanced Compton Telescope (ACT) is being investigated to address the promising science offered in this spectral band. A key element of this investigation is the development of a general set of tools to simulate the background environment for a range of low Earth orbits, and model how this background will propagate through a given instrument design. Results calculated with this tool system will be used to predict science capabilities for ACT instrument concepts, and will also be applicable to other future gamma-ray instruments. We will report on the progress in developing this capability, and preliminary results on its application to ACT instrument concepts. ACT is being studied, and this simulations package is being integrated through, the NASA Vision Mission concept study.
