SANDY release 1.0 new features and major updates

ENDF-6 file interface

Reading / writing

Remove any fortran element to simplify installation (highest priority ❗).

Nuclear data sampling

• Stochastic sampling of ENDF-6 nuclear data via command-line interface for:

  • Cross sections (targeting a first pre-release)
  • Nubar (targeting a second pre-release)
  • Angular distributions (this can be broken in pre-release)
  • Energy distributions (this can be broken in pre-release)

  This process shall mimic what was already available.

• Object-oriented implementation of the sampling pipeline via class sandy.Endf6

  • sandy.Endf6.get_perturbations
  • sandy.Endf6.apply_perturbations

This allows extra flexibility to users, such as:

• storing perturbation coefficients (less storage space, reproducibility) that can be applied on-the-fly
• modify the pipeline by, for instance, applying perturbations to Doppler-Broadened cross sections
