Abstract

Perfeccionamientos en ensamblajes de combustibles nucleares del tipo que comprenden al menos un haz de agujas de combustible envainado dispuestas según una red regular en una carcasa que delimitan un conducto recorrido por un fluido refrigerante, comprendiendo cada aguja, sobre la mayor parte al menos de su longitud, un atirantado en hélice que fija la separación mínima entre la aguja y las agujas adyacentes o la carcasa, caracterizado porque la carcasa presente sobre su superficie interna, unos vaciados en los que se encajan parcialmente los tirantes de las agujas laterales del haz.
