openmc.deplete.cram.CRAM48

openmc.deplete.cram.CRAM48(A, n0, dt, substeps=1)

Solve depletion equations using IPF CRAM

Parameters:

  • A (scipy.sparse.csc_array) – Sparse transmutation matrix A[j, i] desribing rates at which isotope i transmutes to isotope j

  • n0 (numpy.ndarray) – Initial compositions, typically given in number of atoms in some material or an atom density

  • dt (float) – Time [s] of the specific interval to be solved

  • substeps (int, optional) – Number of substeps per depletion interval.

Returns:

Final compositions after dt

Return type:

numpy.ndarray
