Armi Half Life Data Error #1681

Open tp-pbritt-nuc opened 2 months ago

tp-pbritt-nuc commented 2 months ago

These isotopes have half lives greater than 10% off from a proprietary dataset developed from ENDF 7.1 compared with what's stored in ARMI nuclideBases.

@sombrereau -- is interested in this

My solution for this is to allow users to set which nuclide data source they want to use. It is strange that ARMI enforces one data set.

But the nuclide data is currently global, so the the order of operations to solve this ticket is:

  1. Move Global Nuclides out of the global scope
  2. New Setting to swap in different nuclide data
