class ogstools.physics.nuclearwasteheat.nuclearwaste.NuclearWaste

Bases: object

Models the heat generated by one type of nuclear fuel waste.

name: str

Name of this type of waste.

nuclide_powers: PlainQuantity | ndarray

Powers for the different leading nuclides.

decay_consts: PlainQuantity | ndarray

Decay constants for the different leading nuclides.

num_bundles: int

Number of nuclear waste bundles.

time_interim: PlainQuantity | float

Interim storage time before heat evaluation.

time_deposit: PlainQuantity | float = 0.0

Number of active bundles linearly increases until this time is reached.

__init__(name, nuclide_powers, decay_consts, num_bundles, time_interim, time_deposit=0.0, factor=1.0)

Parameters:

• name (str)

• nuclide_powers (PlainQuantity | ndarray)

• decay_consts (PlainQuantity | ndarray)

• num_bundles (int)

• time_interim (PlainQuantity | float)

• time_deposit (PlainQuantity | float)

• factor (PlainQuantity | float)

Return type:

None

factor: PlainQuantity | float = 1.0

Scale the calculated heat by this factor.

heat(t, baseline=False, ncl_id=None, time_unit='s', power_unit='W')

Calculate the heat of a nuclear waste proxy model.

Parameters:

• t (PlainQuantity | float | ndarray) – Timevalue(s) at which the heat is calculated.

• ncl_id (int | None) – If given, only output the heat by nuclide with this id, else sum the heat over all nuclides.

• baseline (bool) – If True, evaluate one bundle with no interim or deposition time delay.

• time_unit (str)

• power_unit (str)

Returns:

Heat generated by the nuclear waste at time t.

Return type:

float | ndarray

class ogstools.physics.nuclearwasteheat.nuclearwaste.Repository

Bases: object

Models the heat generated by total repository inventory.

__init__(waste)

Parameters:

waste (list[NuclearWaste])

Return type:

None

waste: list[NuclearWaste]

Waste inventory of the repository.

time_deposit(time_unit='s')

Deposition time for each nuclear waste type.

Parameters:

time_unit (str)

Return type:

float | list[float]

heat(t, baseline=False, ncl_id=None, time_unit='s', power_unit='W')

Calculate the heat produced by the repository at time t.

Parameters:

• t (PlainQuantity | float | ndarray) – Timevalue(s) at which the heat is calculated.

• ncl_id (int | None) – If given, only output the heat by nuclide with this id, else sum the heat over all nuclides.

• baseline (bool) – If True, evaluate one bundle for each waste with no interim or deposition time delay.

• time_unit (str)

• power_unit (str)

Returns:

Heat generated by the repository at time t.

Return type:

float | ndarray
