This is an implementation of the rigorous 2-step (R2S) method to calculate shutdown dose rates (SDDR) due to neutron irradiation of materials. The method comprises the following steps: (1) Simulation of neutron transport to obtain neutron flux spatial and energy distribution; (2) inventory calculations and activation analysis to obtain decay gamma source intensity and spactra as spatial distribution; (3) simulation of the decay gamma transport. The R2Smesh system presented in this repo organizes dataflow between the steps.
There are several stand-alone codes to simulate neutron and gamma transport and to perform inventory calculations. This system uses MCNP5 for neutron and gamma transport and FISPACT-II for inventory calculations.
The implementation in this repo is written from scratch, but in some aspects mimics the R2Smesh developed in KIT/INR in 2005 (?) -- 2014.
A short recipe how to start calculations can be found in the recipe and deploy.
Feel free to propose a new feature by adding an issue with the enhancement label. As examples, look to already existing proposals. Alternatively (e.g. if you don't have the github account), contact the development team directly: r2smesh@gmail.com
