Description

Depletion results get nuclide density and reaction rate information from activation calculations.

It would be useful to suppress the reaction rate data from going into the depletion_results.h5 file.

In a R2S large mesh:

 Time Steps: 37
 Materials: 39000
 Nuclides: 1447

The file size reduces from original 700 GB to 10 GB. This helps with RAM, disk space, etc. etc.

Alternatives

I have been using custom Python utilities to strip the data out after the fact.

Compatibility

This will certainly create issues with other uses of a depletion_results.h5 file (true fission style depletion).
Whereas this isn't terribly problematic in fusion with "static" systems.

Perhaps an R2S depletion_results.lite.h5 (intended for independent operator rather than coupled)
