Abstract
Lambda modes of a nuclear power reactor have interest in reactor physics since they have been used to
develop modal methods and to study BWR reactor instabilities. An h–p-Adaptation finite element method
has been implemented to compute the dominant modes the fundamental mode and the next subcritical
modes of a nuclear reactor. The performance of this method has been studied in three benchmark problems,
a homogeneous 2D reactor, the 2D BIBLIS reactor and the 3D IAEA reactor.
