Welcome to Héricendre

Héricendre is a standalone Bateman equation solver. Its purpose is to be easy to use through human readable yaml input file as well as (in the future) a python API. Its secondary purpose is to teach myself c++.

It uses depletion chain in the OpenMC xml format.

Roadmap

Depletion:

  • Add HDF5 result files
  • Support neutron reactions (no fission)
    • Find a suitable file format to store multigroup cross-sections
  • Support secondary particle for neutron reactions
  • Support fission

Utilities:

  • Support chain reduction

An example:

Solver: Decay
Chain: /home/nlinden/workspace/hericendre/data/chain-jeff33-long.xml
Results: results_decay.csv
TimeMode: Timestamps
Time: >
  logspace 1e-10 1e17 271 ;
  1e17
ConcentrationMode: Uniform
Concentrations: 1.

Another:

Solver: CRAM48
Chain: /home/nlinden/workspace/hericendre/data/chain-jeff33-long.xml
Results: results_decay.csv
TimeMode: Timestamps
Time: >
  logspace 1e-10 1e17 271 ;
  1e17
ConcentrationMode: Explicit
Concentrations: >
  Pu239 10.
  U235 10.
