Fuel-needle bundles for nuclear reactors

Creators

Description

This bundle, each needle of which is provided with a cross-member wound in a high-pitch spiral on the outer surface of the needle sheath and made integral with the needle end-plugs, is characterized in that said cross-member consists of a deformable tube of constant initial cross section. This can apply to high-power fast neutron nuclear reactors

Abstract (French)

Ce faisceau, dans lequel est prevu sur chaque aiguille un organe d'entretoisement enroule en helice a grand pas sur la surface externe de la gaine de l'aiguille et solidarise des bouchons d'extremite de cette aiguille, se caracterise en ce que cet organe est constitue par un tube deformable de section initiale constante. Ceci est applicable aux reacteurs nucleaires a neutrons rapides de puissance elevee
