An Application of Reduced Basis Methods to Core Computation in APOLLO3
Yonah Conjungo Taumhas, Geneviève Dusson, Virginie Ehrlacher +2
In the aim of reducing the computational cost of the resolution of parameter-dependent eigenvalue problems, a model order reduction (MOR) procedure is proposed. We focus on the cas…

Reduced basis method for non-symmetric eigenvalue problems: application to the multigroup neutron diffusion equations
Yonah Conjungo Taumhas, Geneviève Dusson, Virginie Ehrlacher +2
In this article, we propose a reduced basis method for parametrized non-symmetric eigenvalue problems arising in the loading pattern optimization of a nuclear core in neutronics. T…

Impact of physical model error on State Estimation for neutronics applications
Y. Conjungo Taumhas, D. Labeurthre, F. Madiot +2
In this paper, we consider the inverse problem of state estimation of nuclear power fields in a power plant from a limited number of observations of the neutron flux. For this, we…
