Abstract
Perfeccionamientos introducidos en un conjunto de elementos de combustible nuclear, que comprende un haz de agujas enfundadas, mantenidas paralelas entre sí, según los nudos de una red regular, por un conjunto de rejillas separadas, provistas de órganos de apoyo sobre estas agujas, y una estructura rígida, formada por dos placas de extremo paralelas, arriostradas por tirantes, que se distribuyen con regularidad entre la red de las agujas según nudos de esta red, siendo estos tirantes sensiblemente del mismo diámetro que las agujas, caracterizados porque el haz de agujas está asociado a una rejilla de soporte única, que se hace solidaria de los tirantes, estando distribuidas las demás rejillas a ambos lados de la rejilla de soporte y según la altura del conjunto, de tal modo que los alargamientos de las agujas se producen a partir de la citada rejilla de soporte, hacia las placas inferior y superior respectivamente.
