ogstools.physics.nuclearwasteheat.nuclearwaste module#

class ogstools.physics.nuclearwasteheat.nuclearwaste.NuclearWaste[source]#

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)#
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')[source]#

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.

Return type:

float | ndarray

Returns:

Heat generated by the nuclear waste at time t.

class ogstools.physics.nuclearwasteheat.nuclearwaste.Repository[source]#

Bases: object

Models the heat generated by total repository inventory.

__init__(waste)#
waste: list[NuclearWaste]#

Waste inventory of the repository.

time_deposit(time_unit='s')[source]#

Deposition time for each nuclear waste type.

Return type:

float | list[float]

heat(t, baseline=False, ncl_id=None, time_unit='s', power_unit='W')[source]#

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.

Return type:

float | ndarray

Returns:

Heat generated by the repository at time t.
