Abstract

UN ESPACIADOR ENREJADO, PARA UN CONJUNTO A FUEL DE REACTOR NUCLEAR, ESTA FORMADO POR DOS PEINES SUPERPUESTOS (6, 8). CADA PEINE (6, 8) TIENE UNA TIRA BASE (10) QUE SE EXTIENDE A LO ANCHO DEL CONJUNTO. SE LE UNEN PARALELAMENTE TIRAS ENREJADAS (12) QUE ESTAN LIBRES EN LOS OTROS EXTREMOS. LAS TIRAS ENREJADAS CON PERPENDICULARES A LA TIRA BASE Y ESTAN FORMADAS POR RESORTE (14) JUNTO CON LAS VARILLAS DE FUEL (4) DEL CONJUNTO. LOS PEINES (6, 8) PUEDEN INSERTARSE DESDE LOS LADOS DEL CONJUNTO, PARA QUE UN ESPACIDOR ADICIONAL O SUSTITUTIVO, PUEDA AÑADIRSE AL CONJUNTO SIN DESACOPLAR EL ULTIMO.
