Abstract

EL ELEMENTO DE COMBUSTION PARA REACTORES NUCLEARES POSEE UN ESPACIADOR EN (22,25) DE LOS DOS TRAPECIOS. FORMA DE REJILLA PROVISTO DE UNA MALLA INTERIOR, CUYO CONTORNO ESTA FORMADO POR EL CONTORNO EXTERIOR DE DOS TRAPECIOS ISOSCELES, CUYAS BASES MAS LARGAS CAEN - UNA EN TODA SU EXTENSION Y LA OTRA RECUBRIENDOLA- EN UNA RECTA (9). LAS BASES MAS CORTAS (20, 21, 30, 31) DE ESTOS DOS TRAPECIOS ESTAN A LA MISMA DISTANCIA DE LA RECTA (9) Y COMO MINIMO UNA DE ESTAS DOS BASES MAS CORTAS TIENE UNA LONGITUD DIFERENTE A LA DE LOS CUATRO LADOS IGUALES\!THE COMBUSTION ELEMENT FOR NUCLEAR REACTORS HAS A SPACER AT (22,25) OF THE TWO TRAPEZES. GRID FORM PROVIDED WITH AN INTERIOR MESH, WHICH CONTOUR IS FORMED BY THE EXTERNAL CONTOUR OF TWO ISOSCELES TRAPEZES, WHOSE LONGER BASES FALL - ONE IN ITS ENTIRE EXTENSION AND THE OTHER COVERING IT - ON A STRAIGHT LINE (9). THE SHORTER BASES (20, 21, 30, 31) OF THESE TWO TRAPEZES ARE AT THE SAME DISTANCE FROM THE STRAIGHT LINE (9) AND AT LEAST ONE OF THESE TWO SHORTER BASES HAS A DIFFERENT LENGTH THAN THAT OF THE FOUR SAME SIDES \ !
