openmc.deplete.AtomNumber

class openmc.deplete.AtomNumber(local_mats, nuclides, volume, n_nuc_burn)[source]

Stores local material compositions (atoms of each nuclide).

Parameters

  • local_mats (list of str) – Material IDs

  • nuclides (list of str) – Nuclides to be tracked

  • volume (dict) – Volume of each material in [cm^3]

  • n_nuc_burn (int) – Number of nuclides to be burned.

Variables

  • index_mat (dict) – A dictionary mapping material ID as string to index.

  • index_nuc (dict) – A dictionary mapping nuclide name to index.

  • volume (numpy.ndarray) – Volume of each material in [cm^3]. If a volume is not found, it defaults to 1 so that reading density still works correctly.

  • number (numpy.ndarray) – Array storing total atoms for each material/nuclide

  • materials (list of str) – Material IDs as strings

  • nuclides (list of str) – All nuclide names

  • burnable_nuclides (list of str) – Burnable nuclides names. Used for sorting the simulation.

  • n_nuc_burn (int) – Number of burnable nuclides.

  • n_nuc (int) – Number of nuclides.

get_atom_densities(mat, units='atom/b-cm')[source]

Return atom densities for a given material

Parameters

  • mat (str, int, openmc.Material or slice) – Material index.

  • units ({"atom/b-cm", "atom/cm3"}, optional) –

    Units for the returned concentration. Default is "atom/b-cm"

    New in version 0.13.1.

Returns

Dictionary mapping nuclides to atom densities

Return type

dict

get_atom_density(mat, nuc)[source]

Return atom density of given material and nuclide

Parameters
Returns

Density in [atom/cm^3]

Return type

numpy.ndarray

get_mat_slice(mat)[source]

Gets atom quantity indexed by mats for all burned nuclides

Parameters

mat (str, int, openmc.Material or slice) – Material index.

Returns

The slice requested in [atom].

Return type

numpy.ndarray

get_mat_volume(mat)[source]

Return material volume

Parameters

mat (str, int, openmc.Material, or slice) – Material index.

Returns

Material volume in [cm^3]

Return type

float

set_atom_density(mat, nuc, val)[source]

Sets atom density instead of total number.

Parameters
set_density(total_density)[source]

Sets density.

Sets the density in the exact same order as total_density_list outputs, allowing for internal consistency

Parameters

total_density (list of numpy.ndarray) – Total atoms.

set_mat_slice(mat, val)[source]

Sets atom quantity indexed by mats for all burned nuclides

Parameters
