A multigrid method to compute the dominant lambda modes of a nuclear reactor

Carreño, Amanda; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (International Center for Numerical Methods in Engineering (CIMNE), 2017-07-05)

[Otros] High accuracy is required for the solution of the lambda modes problem associated with the neutron diffusion equation. In this work, a multigrid method based on finite element method has been proposed to solve this ...
Block hybrid multilevel method to compute the dominant lambda-modes of the neutron diffusion equation

Carreño, A.; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2018)

[EN] The dominant lambda-modes associated with a nuclear reactor configuration describe the neutron steady-state distribution and its criticality. Furthermore, they are useful to develop modal methods to study reactor ...
Block Preconditioning Matrices for the Newton Method to Compute the Dominant lambda-Modes Associated with the Neutron Diffusion Equation

Carreño, Amanda; Bergamaschi, Luca; Martinez, Angeles; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (MDPI AG, 2019-03)

[EN] In nuclear engineering, the lambda-modes associated with the neutron diffusion equation are applied to study the criticality of reactors and to develop modal methods for the transient analysis. The differential ...
Integration methods for the time dependent neutron diffusion equation and other approximations of the neutron transport equation

Carreño Sánchez, Amanda María (Universitat Politècnica de València, 2020-06-01)

[ES] Uno de los objetivos más importantes en el análisis de la seguridad en el campo de la ingeniería nuclear es el cálculo, rápido y preciso, de la evolución de la potencia dentro del núcleo del reactor. La distribución ...
Modal methods for the neutron diffusion equation using different spatial modes

Carreño, A.; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2019-08)

[EN] The behaviour of the neutrons inside a nuclear reactor core can be modelled by using the time dependent neutron diffusion equation. Different time schemes have been used to integrate this equation. One possibility is ...
Multilevel method to compute the lambda modes of the neutron diffusion equation

Carreño, A.; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (UP4 Institute of Sciences, S.L., 2017)

[EN] Determination of the reactor kinetic characteristics is very important for the design and development of a new reactor system. In this sense, the computation of lambda modes associated to a nuclear power reactor has ...
Spatial modes for the neutron diffusion equation and their computation

Carreño, A.; Vidal-Ferràndiz, Antoni; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2017)

[EN] Different spatial modes can be defined for the neutron diffusion equation such as the k; a and c-modes. These modes have been successfully used for the analysis of nuclear reactor characteristics. In this work, these ...
