Abstract

Conjunto de armazón en forma de estrella para soportar una pluralidad de varillas de control de modo que puedan efectuar un movimiento vertical en un reactor nuclear, teniendo dicho conjunto de armazón en forma de estrella un cubo central, una pluralidad de aspas separadas las unas de las otras circunferencialmente alrededor de dicho cubo y que se extienden radialmente a partir del mismo, y una pluralidad de dedos asociados con una de dichas aspas para su conexión con las varillas de control, caracterizado porque cada una de dichas aspas (34), conjuntamente a los dedos (36) que lleva, es de construcción monolítica de una sola pieza que forma una subunidad estructural rígida desprovista de uniones.
