Abstract

MEDIDOR DE CONSTANTE ELASTICA EN MUELLES DE SEPARADORES DE HACES DE COMBUSTIBLE NUCLEAR. PARA MEDIR LAS CONSTANTE ELASTICAS DE MUELLES DE DOBLE EFECTO PARA CENTRADO DE BARRAS DE COMBUSTIBLE MONTADOS CON DIFERENTES PARES DE FERULAS EN UN SEPARADOR DE HAZ DE COMBUSTIBLE NUCLEAR, SE PROVEE UN MEDIDOR QUE INCLUYE UNA BARRA DE ALINEACION Y UNA SONDA PORTADAS POR UN MANGO PARA INSERTARLAS EN LAS FERULAS DE UN PAR DE FERULAS. LA BARRA DE ALINEACION CARGA EL LADO DEL MUELLE QUE ACTUA EN SU FERULA, MIENTRAS QUE EL OTRO LADO DEL MUELLE EJERCE SU FUERZA DE CENTRADO DE BARRA DE COMBUSTIBLE SOBRE UNA CELULA DE CARGA PORTADA POR LA SONDA. UN MICROMETRO ACTUA CONTRA LA CELULA DE CARGA PARA PRODUCIR FLEXIONES MEDIDAS DEL OTRO LADO DEL MUELLE. LAS CONSTANTES ELASTICAS SE CALCULAN A PARTIR DE LAS LECTURAS ELECTRICAS DE FUERZA DE MUELLE Y FLEXION DE MUELLE DE LA CELULA DE CARGA Y DEL MICROMETRO.
