Files associated with R2S Step2

[anu1217]

fixes #21

-- Adding input files needed for Step 2 of R2S
-- The irradiation schedule was changed in the ALARA input file created in Step 1 to match the parameters specified in OpenMC
-- The config file is the same as the one in #25

I assume this gets set in the config.ini but you probably want a larger source normalization. This has 1e10 for 3e8 seconds (3years). We have 3.55E17 n/MJ of fusion energy, or a source strength of 3.55E17 n/s for each MW of fusion energy. You may want to increase this source normalization to see if that gives you more variation in the photon source over time

The source normalization is set manually in the ALARA input file created by config.ini - by default it's set to 1e10. I changed it to 1e18, which results in a larger and more varied photon distribution. However, the mesh distribution created at each of the two decay timesteps is exactly the same (source.h5m), although the number of photons/second emitted (photon_source_intensities.txt) is different. I could add these files here, but I'm not sure if the R2S output belongs in this particular PR.

When I look at the phtn_src file, I see evidence that they are different at different shutdown times.

This bash command will only look at the TOTAL photon source (rather than the nuclide-specific source), and will exclude the lines for shutdown

prompt%> grep ^TOTAL phtn_src | grep -v shutdown | less

As I scroll through, I see a surprising number of results with 0 photon source (that's maybe a different problem), but most mesh elements that have any photon source have different values at 24 h and 1 month.

How can you tell the two files are the same?
