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.

## msre core
![](core/docs/msre.png)
[core/msrecore.pdf](core/docs/msrecore.pdf) lists reference of the msre core design, documented in the old msre reports and located in the repository [github.com/openmsr/msr-archive](https://github.com/openmsr/msr-archive/blob/master/README.md).

the work-in-progress cad model can be found [here](https://cad.onshape.com/documents/4f04f63bfd4138a61a54b3f8/w/11cb17d9ef25bb27f8ada6c0/e/72f417dd8eb3e2fa4f9ccb9e) on onshape.

## prerequisites 
### CAD_to_openMC
[CAD_to_openMC](https://github.com/openmsr/CAD_to_openMC) is an open-source package to convert CAD geometry (in the form of '.step' files) into an openmc-readable h5m file

### openmc
these simulations use [openmc](https://docs.openmc.org/en/stable/). automated source installation scripts for linux can be found [here](https://github.com/openmsr/openmc_install_scripts)

## simulation guide

first, clone the repository

```
git clone https://github.com/openmsr/are.git
```

enter the are folder and run the `run.sh` script

```
cd are
bash run.sh
```


## msre heat exchangers

open-access [master's thesis](https://ltu.diva-portal.org/smash/get/diva2:1546993/FULLTEXT01.pdf) produced by Malcolm Akner about simulations of the heat exchangers of the msre, titled: 

Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations
- A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

### msre primary heat exchanger
