detailed cad model of the [msre](https://en.wikipedia.org/wiki/Molten-Salt_Reactor_Experiment) (molten salt reactor experiment), operated by oak ridge national laboratory 1965-69. detailed cad model and openmc benchmarks of the [msre](https://en.wikipedia.org/wiki/Molten-Salt_Reactor_Experiment) (molten salt reactor experiment), operated by oak ridge national laboratory 1965-69.
## msre core [onshape cad model v17](https://cad.onshape.com/documents/4f04f63bfd4138a61a54b3f8/v/b8c29a0cedda86dfc6948111/)
![](core/docs/msre.png) cad model includes crude drawings of the insulation, thermal shield, and the reactor pit, but not detailes such as components or piping.
all part names' begining correspond to it's material, e.g. graphite, salt, or inor-8 (hasteloy n).
all core parts are thermally expanded to the operating temperature (currently to the temperature of the zero power experiments during commisioning). note that graphite thermal expansion coefficients are only given for room temperature and thus likely underpredicted and the control rod assembly temperature is unknow and like much higher than currently assigned.
[core/msrecore.pdf](core/docs/msrecore.pdf) lists reference of the msre core design, documented in the old msre reports and located [here](https://github.com/openmsr/msr-archive/blob/master/README.md).

## h5m ![](core/docs/msre.png)
[h5m](h5m/) surface mesh of the previous step files for OpenMC simulation.
**Note:** the h5m files are generated with `Coreform Cubit` with a surface tolerance of 1e-2 cm. ![](core/docs/msre-pit.png)
## docker msre # openmc benchmark
[msre docker](msre_docker/) conatiner which includes not only support for OpenMC with DAGMC/MOAB, embree, and double_down libraries, but also a Jupyter notebook server. openmc benchmark include:
## openmc notebooks
[openmc notebooks](openmc_notebooks/) of the msre in form of jupyter notebooks.
Examples include:
- msre cad with settable control rods - msre cad with settable control rods
- msre isothermal temperature coefficient calculation - msre isothermal temperature coefficient calculation
- msre depletion analysis with fission products removal - msre depletion analysis with fission products removal
