The PINSPEC project project aims to provide a simple-to-use Python package for spectral calculations of nuclear reactor applications. It includes support for infinite homogeneous spectral calculations, heterogeneous-homogeneous pin cell equivalence calculations, as well as constructive solid geometry and 3D ray tracing for fully heterogeneous calculations. A basic ENDF-VII continuous energy cross-section is provided with support for the user to make additions to the library for their own applications. The project started under the Computational Reactor Physics Group at MIT.

Complete documentation on the usage of PINSPEC is hosted on our GitHub wiki at https://github.com/mit-crpg/PINSPEC/wiki. If you are interested in the project or would like to help and contribute, please contact the development team. In addition, PINSPEC hosts a collection of publicly readable Evernote notebooks to allow for free and open collaboration between users and the development team. If you plan to use PINSPEC frequently and would like to contribute notes and feedback through Evernote, please contact the development team.

Detailed installation instructions can be found in the User's Guide.

If you run into problems installing or running PINSPEC, first review the FAQ in the Wiki and the Evernote notebooks for info from other users regarding your issue. If you are not able to find a solution to your problem there, please contact one of the developers.

All bugs are reported through the Issues Evernote notebook. This allows for users to submit their input files, modified source code, as well as images (ie, plots) along with their bugs.

PINSPEC is undergoing review to be distributed under the MIT/X license.
