Abstract
UNA VAINA PARA COMBUSTIBLE NUCLEAR. DICHA VAINA PARA COMBUSTIBLE NUCLEAR. DICHA VAINA (1) ESTA FORMADA POR TRES CAPAS DIFERENTES: UNA CAPA INTERMEDIA (5) FORMADA POR UNA MEZCLA DE UN MATERIAL ABSORBENTE CONSUMIBLE, QUE CONTIENE BORO Y UNA ALEACION DE ZIRCONIO, Y UNA CAPA INTERNA (9) DE ZIRCONIO METALICO QUE EVITA LA TENSOCORROSION Y EL POSIBLE FALLO DE LA VAINA (1) A CAUSA DE LA INTERACCION PASTILLA-VAINA. LA CAPA EXTERNA (3) DE LA VAINA (1) TIENE UN ESPESOR AL MENOS DOBLE DE LA SUMA DE LOS DE LAS OTRAS DOS CAPAS, DE LAS QUE LA CAPA INTERMEDIA (5) ES LA DE ESPESOR MAYOR. EN EL INTERIOR DE LA VAINA (1) SE ENCIERRAN HERMETICAMENTE LAS PASTILLAS DE COMBUSTIBLE (15) MEDIANTE UN TAPON (17) EN LA PARTE INFERIOR Y UNA TAPA SUPERIOR (19), AMBOS DE ZIRCALOY. ENTRE LA PASTILLA SUPERIOR Y LA TAPA SUPERIOR (19) SE DISPONE LA CAMARA DE PREVISION (21) Y UN ELEMENTO DERIVADOR, P. EJ. UN RESORTE (23) QUE REFRENA LAS PASTILLAS (15) EN EL INTERIOR DE LA VAINA (1).
