Abstract

PARA EFECTUAR UNA INSPECCION SEGURA Y DE CALIDAD DE LAS CARACTERISTICAS DIMENSIONALES DE LAS CELDAS (10) QUE SE INCORPORAN EN LOS SEPARADORES (12) UTILIZADOS EN LOS MAZOS DE COMBUSTIBLE NUCLEAR PARA ESTABLECER LAS SEPARACIONES CRITICAS ENTRE LAS VARILLAS DE COMBUSTIBLE (14), SE COLOCA UNA CELDA (10) EN UNA FIJACION (20, 44) DIMENSIONADA PARA CALIBRAR LAS DIMENSIONES EXTERIORES DE LA CELDA (10). UN PASADOR QUE SIMULA UNA VARILLA DE COMBUSTIBLE (30, 38) SE INSERTA ENTONCES A TRAVES DE LA CELDA PARA DESCANSAR SOBRE LOS TOPES DE POSICIONAMIENTO DE LAS VARILLAS DE COMBUSTIBLE (16) FORMADO SOBRE LA CELDA. UNOS CALIBRADORES (32, 34) COMPRUEBAN ENTONCES LAS DIMENSIONES DE LOS HUECOS ENTRE LAS FIJACIONES (20, 44) Y EL PASADOR DE SIMULACION.
