mcdc.IC_generator

mcdc.IC_generator(N_neutron=0, N_precursor=0, cycle_stretch=1.0, neutron_density=None, max_neutron_density=None, precursor_density=None, max_precursor_density=None)

Activate initial condition generator.

The initial condition generator samples initial neutrons and precursors during an eigenvalue simulation.

Parameters

N_neutronint

Neutron target size.

N_precursorint

Delayed neutron precursor target size.

cycle_stretchfloat

Factor to stretch number of cycles. Higher cycle stretch reduces inter-cycle correlation.

neutron_density, max_neutron_densityfloat

Total and maximum neutron density, required if N_neutron > 0.

precursor_density, max_precursor_densityfloat

Total and maximum precursor density, required if N_precursor > 0.

Returns

None (in-place card alterations).
