Welcome to the Computational Reactor Physics Group (CRPG) in the department of Nuclear Science and Engineering at MIT !

CRPG focuses on the development of novel methods for accurate and efficient nuclear reactor simulations. Better simulations help the nuclear industry set well-informed safety margins, but also enable assessment of innovative new fuel and reactor designs. From accurate quantification of uncertainty of neutron cross sections to exascale simulation of light water reactors, computing is pushing the boundaries of reactor physics.


We are committed to making our research accessible to the community and build up collaboration with other research groups. On Github you’ll find our latest research tools: open-source reactor analysis software OpenMC and OpenMOC, a multi-physics ready neutron cross section library, the BEAVRS pressurized water reactor benchmark and much more.
