saltproc.materialflow module

class saltproc.materialflow.Materialflow(comp=None, mass=-1.0, density=1.0, atoms_per_molecule=-1.0, metadata=None, vol=1.0, temp=900, mass_flowrate=0.0, void_frac=0.0, burnup=0.0)[source]

Bases: Material

Class contains information about burnable material flow. Based on PyNE Material.

__add__(y)[source]

Overrides Python adding operation for Materialflow objects.

Parameters

  • x (obj) – Materialflow object #1.

  • y (obj) – Materialflow object #2.

Returns

Materialflow which is a sum of isotope masses from x and y.

Return type

obj

__deepcopy__(memo)[source]

Return a deep copy of compound object self.

Parameters

  • self (obj) – Compound object.

  • memo (dict, optional) – Id-to-object correspondence to control for recursion.

Returns

New compound object copied from self.

Return type

obj

__eq__(other)[source]

Overrides Python = operation to compare two Materialflow objects. Compares objects total mass, density, atoms_per_molecule, temperature, mass flowrate, and masses of important isotopes: uranium-235 and uranium-238.

Parameters

other (obj) – Materialflow object to compare with.

Returns

Are the objects equal?

Return type

bool

__init__(comp=None, mass=-1.0, density=1.0, atoms_per_molecule=-1.0, metadata=None, vol=1.0, temp=900, mass_flowrate=0.0, void_frac=0.0, burnup=0.0)[source]

Initializes the Materialflow object.

Parameters

  • PyNE.Material (class) – PyNE Material parent class containing nuclide vector, density, mass, atoms_per_molecule, metadata

  • temp (float) – temperature of the material flow (K)

  • mass_flowrate (float) – mass flow rate of the material flow (g/s)

  • void_frac (float) – void fraction in the material (%)

  • burnup (float) – material burnup at the end of depletion step [MWd/kgU]

__rmul__(scaling_factor)[source]

Overrides Python multiplication operation for Materialflow objects.

Parameters

scaling_factor (float or int) – Scaling factor.

Returns

Materialflow object which has mass of each isotope and mass_flowrate scaled by other.

Return type

obj

copy_pymat_attrs(src)[source]

Copies PyNE attributites from source object (src) to target object.

Parameters

src (obj) – Materialflow object to copy attributes from.

get_mass()[source]

Returns total mass of the material descibed in Materialflow object.

Returns

The mass of the object.

Return type

float

print_attr()[source]

Prints various attributes of Materialflow object.

scale_matflow(f=1.0)[source]

Returns nuclide vector dictionary, obtained from object attrs and then scaled by factor.

Parameters

f (float) – Scaling factor.

Returns

new_mat_comp – Materialflow nuclide component dictionary of relative mass.

key

The keys are preserved from PyNE Material (integers representing nuclides in id-form).

value

Each nuclide’s mass fraction, multiplied by factor f.

Return type

dict of int to float
