[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 ...
[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 ...
[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 ...

[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 ...
[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 ...

[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 ...
[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 ...
