Run Error : SaltProc - OpenMC

[ecemcimen]

Hello ,
In order to run the SaltProc code with OpenMC, everything required was done during the installation stage. However, when python saltproc -s 2 -i tests/openmc_data /tap_input.json is run, the error is as follows:

Traceback (most recent call last):
File "/home/user1/miniconda3/envs/removal/lib/python3.9/runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,
File "/home/user1/miniconda3/envs/removal/lib/python3.9/runpy.py", line 87, in _run_code
exec(code, run_globals)

print('Initiating Saltproc:\n'
TypeError: can only concatenate str (not "dict") to str

In addition :

While all the requirements are installed via conda, the latest version of openmc 0.13.2 is installed via source because it is not via conda. Therefore, when conda list is called, pyne , saltproc and others, which are SaltProc's requirements, appear, while openmc 0.13.2 version does not.

How can this problem be resolved? Thanks ....

Hi @ecemcimen,

What operating system are you on?
Also, not that there is no tap_input.json file in tests/openmc_data. Can you post the input file you are trying to run?

[ecemcimen]

My operating system Ubuntu on Linux .
The input file I want to run through OPENMC is as follows:
{
"proc_input_file": "../tap_processes.json",
"dot_input_file": "../tap_paths.dot",
"n_depletion_steps": 2,
"depcode": {
"codename": "openmc",
"template_input_file_path": {
"materials": "tap_materials.xml",
"settings": "tap_settings.xml"
},
"geo_file_paths": ["tap_geometry_base.xml"],
"chain_file_path": "test_chain.xml"
},
"simulation": {
"sim_name": "tap_test_simulation_openmc"
},
"reactor": {
"volume": 1.0,
"mass_flowrate": 9.92E+6,
"power_levels": [ 1.250E+9 ],
"depletion_timesteps": [ 5 ],
"timestep_units": "d"
}
}

There is tap_input.json in the SaltProc file downloaded.

In the v0.5.0-pre pre-release, there is no TAP MSR model that can run with OpenMC, only an MSBR model, so I'm not sure where you are getting this tests/openmc_data/tap_openmc.json file from...

I think you may have an old version of the SaltProc repository. Please update your master branch, or download the pre-release I linked above.

Have you run the tests to ensure the software is working?

First of all, the v0.5.0 pre version was downloaded. Requirements are also installed ( pyne , openmc ) .
But running python saltproc -s 2 -i tests/openmc_data/msbr_input.json got the following error:

Thanks ...

Hell @ecemcimen, I apologize for my extremely late response. The error seems to be an issue with your OpenMC installation. Try running the OpenMC test suite (if installing OpenMC from source) to ensure that your OpenMC build is working. You can read more about this here. Also, feel free to post in the OpenMC Discourse form where they can help you get your OpenMC build issues figured out.
