Data for: SECOND-ORDER SENSITIVITIES OF A GENERAL FUNCTIONAL OF THE FORWARD AND ADJOINT FLUXES IN A MULTIPLYING NUCLEAR SYSTEM WITH SOURCE

• This work presents an application of the Second-Order Adjoint Sensitivity Analysis Methodology (2nd-ASAM)
• The number of computations within the 2nd-ASAM to obtain the 1st- and 2nd-order response sensitivities to model parameters increases linearly in augmented Hilbert spaces as opposed to increasing exponentially in the original Hilbert space.
• Therefore, the 2nd-ASAM computes exactly all of the 1st- and 2nd-order responses sensitivities to model parameters with unmatched efficiency.
• The system response considered is a nonlinear functional of the forward and adjoint particle fluxes in a multiplying subcritical system comprising a non-fission neutron source, while the system parameters include isotopic number densities, microscopic cross sections, fission spectrum, sources, and detector response functions.
