Frequency-domain models in the SPN approximation for neutron noise calculations

Carreño, Amanda; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2022-06)

[EN] Simulations of the neutron flux fluctuations, known as neutron noise, can be performed by means of the spherical harmonics equations (SPN) approximation with higher accuracy than with the diffusion equation. In this ...
Multilevel matrix-free preconditioner to solve linear systems associated with a the time-dependent SPN equations

Carreño, Amanda; Vidal-Ferràndiz, Antoni; Ginestar, Damián; Verdú, Gumersindo (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] The evolution of the neutronic power inside of a nuclear reactor core can be approximated by means of the diffusive time-dependent simplified spherical harmonics equations (SPN). For the spatial discretization of ...
