openmc.deplete.cram.CRAM48

openmc.deplete.cram.CRAM48(A, n0, dt)

Solve depletion equations using IPF CRAM

Parameters:

• A (scipy.sparse.csr_matrix) – 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

Returns:

Final compositions after dt

Return type:

numpy.ndarray
