Abstract

The fuel rods are supported with their axes parallel in a square array by two inter-meshed systems, of strips. One system made of a weakly absorbing material (pref. zircaloy), has fixed supports (e.g. bosses) for the rods, whilst the other system, made of resilient material (pref. Income) is erected on the first system and has resilient supports for the rods.
