Abstract
Official abstract text for this publication.
An axial power distribution control device includes an axial offset calculation unit 52 , a parameter calculation unit 53 , and an axial offset determining unit 55 . The axial offset determining unit 55 predicts whether a core axial offset of the power distribution is increased or decreased after a current time, based on a major axis of an ellipse drawn by the xenon parameter and the iodine parameter calculated by the parameter calculation unit 53 and the xenon parameter and the iodine parameter at the current time. This makes it possible to predict a change of the axial offset of the power distribution of a reactor for suppressing a xenon oscillation in the reactor.
First claim
Opening claim text (preview).
The invention claimed is: 1. An axial power distribution prediction device, comprising: an axial offset calculation unit that calculates an axial offset of a current power distribution (AO P ), an axial offset of the power distribution which would give a current xenon distribution under equilibrium condition (xenon-corresponding axial offset: AO X ), and an axial offset of the power distribution which would give a current iodine distribution under equilibrium condition (iodine-cor…
